there are 10 mm to a cm. The numbers are centimeters.
The metric system is based on tens
1000 mm to a meter
10mm to a cm
100 cm to a meter
A rough conversion approximately 2.5 cm to an inch.

Most of the trades in Australia work in mm. and / or metres, cm. are not used.

Ex : a kitchen benchtop is 900mm high, a passage door is 2100mm or 2.1m. high. Dual metric / imperial tapes can’t be read from both sides. Timber is sold by the cube or M3

My wife used to be in the rag trade, she works in cm. We have a hard time communicating sometimes.

Yes. Big red numbers are centimeters (cm), each small rule mark is a millimeter (mm).

The conversion rate is 2.54 cm:inch, aka 25.4mm:inch.

As a vet, I learned a lot about the metric system in the military. I know this isn’t what you asked, but it is an amazingly easy system of measurement.

On a side note, where did you get the tape with both? I like that!

From an Australian point of view.

The metric system (SI) was a great idea and upon its introduction cm were not prefered values.
However obviously nobody tried selling that or maybe even asking/telling that to the textile industry and “other” trades.

Once the metric system was introduced commissioned and set to work the board was disbanded and hence the cm were no longer a non prefered sub unit.

The USA being the USA did their own thing, and I guess will always do so (no ill intent infered here by the way)

I use the metric system in preference to the imperial system but have to by way of necessity and need of accuracy to be able to relate to both.

When I did my Engineering Metrology certificate it was all in metric however historicial measurements like the cubit, foot and inch etc were part of the course.

When you study atomic clocks and interferometry in measurement it all falls into place, you just have to keep your wits about you.

As for tape measures well they are back to front as well, we by way of convention read left to right, but try measuring that way!!

If you think thats all too confusing just wait until the introduction of metric time!

I think I hear my Table Saw calling !!

I was in first grade after JC. So of course they taught standard and metric side by side. My dad almost killed me when I said something about a 16mm wrench. Because of the side by side learning I always thought of a cm as about a half inch. Thanks public education, you’re a bunch of jack holes. Yes, haha, I married a teacher.

Several years ago I converted my shop from imperial to metric. It was one of the smartest moves I’ve made in my shop. Measurement mistakes seldom happen when working metric and once you are use to thinking in metric there is much less time spent butt scratching and re-measuring.

The “yellow” FastCap ProCarpenter 16’ tape is Metric/Standard (FastCap’s term). It is a very good tape and can be handy during the transition from thinking imperial to thinking metric.

Nothing wrong with saying a cm is about half an inch, just like saying a meter is about a yard. That is a soft conversion. You wouldn’t mark something out that way, you would actually use a metric ruler wouldn’t you?

Hmmm, if that idiot RayGun hadn’t dismantled everything Carter did, we would probably be using metric exclusively instead of self converting as he predicted (Hmmm a RayGun prediction that didn’t come true, how surprising) and we would all have solar panels.

That comparison was for the OP’s question of which marks are MM or CM.

Personally I hate the Metric system. As an undegreed engineer I face friends all day who are metric gung ho. Thats cool. It got them through school.

I like to Reductio ad absurdum the metric system when the conversation comes up.

If metric then why not:
Metric angles? You know, 100 degrees with 100 divisions there in.
Metric time? 100 hours and 10 minutes and 10 seconds or some such.
Metric calendar? 10 months with 100 days and…you get the idea.
A metric Bible? 100 books with 100 chapters and 100 verses. Who cares if the now shortest verse is “I”?

I get it. Broken down in 100’s and 10’s. I work in thousands all day long. But i wont change*.

  • when the highest bidder (job) is metric i will change. I will go kicking and screaming.

Per the whole metric argument:
To me it is totally irrelevant that there are three countries that are still imperial, and the other two are 3rd world. Thats like saying “Mom, all the kids started smoking, why cant I?” I like to see some logic behind the decision. Not to mention, and this is the biggest, why would one want such a thing as measure mandated by gvt? Let the market decide. Ah, yes, the best answer to all the problems. If vendors cant deal with a company because the company is metric then go metric. It is for that company to decide. If this is for your shop then make the decision based on who will make you the most money. If measurement mistakes are cut in half because you went metric then it is a good idea. If it is easier for you, do it.

As for me and my shop, we will use feet and inches.

There are many costs for companies associated with conversions to and from metric. Assuming they do it correctly of course. Those would go away if we fully converted.

Metric angles and time would be great. Our current system comes from the Sumerians, yup we use a system developed in what is now Iraq. I mean who cares if it is 4,000 years old and needs a periodic fudge factor.

I bet our official weights and measures are based on metric. A foot is probably defined as so many cms or mms.

I’m sorry you never finished school, perhaps you would see the benefits of SI if you had. Is thousandth of an inch really an imperial unit? Sounds decimal based.

If smoking didn’t hurt you and it allowed you to use the same intelligent measurements as the rest of the kids then that is a good comparison, otherwise it is stupid to compare smoking and SI.

The comment about Reagan begs for clarification.

From The United States and the Metric System, NIST LC 1136: “The efforts of the Metric Board were largely ignored by the American public, and, in 1981, the Board reported to Congress that it lacked the clear Congressional mandate necessary to bring about national conversion. Due to this apparent ineffectiveness, and in an effort [by President Reagan] to reduce Federal spending, the Metric Board was disestablished in the fall of 1982.”

Thou of an inch—with inch being the main word here—yes, it is imperial. Maybe i am missing something but just because one breaks an imperial unit into base 10, 100 or 1000 does not convert it to metric.

SI came about as an attempt to decimalize measurements. The fact that you use thousands of an inch shows the imperial system isn’t good enough. Why don’t you use
256ths, 512ths, or 1024ths? That is just silly to use 1,000s when you have 1024ths right there for you to use.

A little history for you: https://en.m.wikipedia.org/wiki/History_of_the_metric_system

Are you sure you understand what an analogy is?

When it comes to an antiquated difficult to use system everyone using a new system is better. A gallon is different in different countries, a foot is different in different countries. A meter is always the same length.

Metric was the ultimate french “pecker measuring”

They devised the meter to be Just a little longer than the “english” Yard.

Sure distances in units of 10 seems easier.

Thanks for sharing that bit of trivial and inconsequential insight there Bob. The thread was about metric and imperial measurements, not political drivel.

28c = 82f, my favorite temp.

My concern with using metric measurements in woodworking is that it is all based on 10, the most common number of human fingers. If you apply Murphy’s Law here, ...

Metric was the ultimate french “pecker measuring”

They devised the meter to be Just a little longer than the “english” Yard.

1/10,000,000th of the distance from the North Pole to the equator was contrived to be just a little bigger?

Sure distances in units of 10 seems easier.

Not seems, is easier! From a micron to kilometre

However there is nothing “magically more accurate” about Celsius vs. Farenheit either.

Yes, zero is based on the freezing point of fresh water and 100 is the boiling point of fresh water. Not blood.

Reminds me of a song ” the Eastern desert lives and breathes at 45 degrees”

You can get used to it.

SI is amazing! take a cubic centimetre of water it weighs 1 gram, heat it up 1 degree takes 1 calorie, 1 cubic liter of water weighs 1 kilogram. Scale up, scale down. Perfection!*

Still is about metric and how the application of it got derailed. Have a nice day.

So what is more “accurate” 212 F or 100 C…...answer NEITHER.
They are just temperature scales.

Suppose we should have gone for Kelvin… so that 0K is “Absolute 0”

then we can have water freeze at 273.16

At the end of the day Metric was about “Standardization” and not Accuracy nor a “Better system”.

It really is what you are accustomed to.
Being in Engineering requires me to convert back and forth…It is not unlike learning another language.

5 degrees C sounds more accurate than 37 F to describe a cold day. Kelvin is an extension of the Celsius scale.

Is standardization a bad thing? I bet if ego was taken out of it we would have been metric in the 1840s.

so if I’m reading a plan that say’s make a mark at 90mm. do I go to the red 90 on the tape or where is that on the tape.
If we had been taught Metric well,we talked about it for maybe 2 days in math class,I understand some conversion,but reading the tape,I’m not sure what I’m looking at.blk numbers are 10’s of mm, and red numbers are 100’s of mm?

That is because the “SIZE” of the degrees is different.
5C is NOT 37F

5C is actually 41F.

Both methods are ACCURATE… Personally I find the Celsius scale a bit too Coarse for things like thermostat settings.

Moving 1 degrees on the celsius scale is the same change as moving 1.8 degrees on the Farenheit scale.

I would rather shift from 74 to 75 for running the AC, than 23.333 to 23.88 degrees
Such a coarse scale is a PITA

If you run a 10K… you could just as ACCURATELY say you ran 6.2 miles.
Both are a measure of distance.
one is no more accurate than the other.

BTW in the 1840’s and the years leading up to the civil war…. we could give a rats behind about going metric, there were much more important issues, than whether we still used the kings measurement systems. It took the french until after teh French revolution in 1789 before they decided to ‘clean up’ the system of miles, hands, stones, etc for measurement.

So I Doubt we would have adopted this 50 years before the french did. (The Meter…. was created as a basis unit in 1791)

- daddywoofdawg

The scale is CM, and 1 CM = 10 MM – the red 90 would be 90cm, or 900mm

if you wanted 90mm, which is 9cm, you would mark it at the first number 9 on the tape. The red numbers are just so the scale doesn’t have to show multiple digits… Similar to how a regular tape shows the feet in red and inches in black (although, it does hit double digits for 10 and 11 inches). On the one above, the first 1-9 is 1-9 (cm), then you get 10, then the 1-9 is 11-19, then you get to 20, then the 1-9 is 21-29 until you get to the 30, and so on.

I would rather shift from 74 to 75 for running the AC, than 23.333 to 23.88 degrees
Such a coarse scale is a PITA

It could be made finer with the addition of a single decimal… 23.3 to 23.8 gives better granularity than 74 to 75. Of course, you could also do the same with Fahrenheit. Either way, it doesn’t seem that big a deal to me, and I would get used to either one pretty easily. Just saying.

Cheers,
Brad
