Well I got tired of feeling old and unteachable and not being able to grasp the whole centigrade/celsius/ferenheit this to that conversion concept and you can only ask your lumberjock buddies so many times before they start thinking you’re too old of a dog to teach, so I went and found a site that has all the conversions i need (so far) on one chart, and posted it to my webpage. So, if there are any other old dogs that can’t seem to convert one thing to another or back, you can find it on my site ,left side top link.

Hi, Obi. Thanks for the link on you site.

The issue of ‘conversions’ is similar to the concept of translating languages. When you first start learning a new language, to understand the new language, it is necessary to constantly translate the new language back to your origin language. This is a slow process. However, as one becomes more familiar with the new languare, the translation becomes quicker until, without realizing that it is happening, you find yourself thinking in the new language. No translation is required.

It’s the same for converting from Imperial measurements to metric. At first you ask yourself, “How long is 1mm in inches?” or “What is 3/8” in metric?” So you find yourself constantly doing math to gain a better understanding of distance or length.

But, if you stop to think about it for a moment, conversion is irrelevant. If your measuring devices are metric, and you hold a metric tape measure against a piece of wood that is 273mm long, what difference does it make how long this is in Imperial. If you are working from a drawing that is in metric, and use metric measures, then it becomes totally irrelevant.

The problem normally arises when you are actually doing a conversion from a drawing that is in one measurement system using measuring tools in another. This becomes hard work and dramatically increases the potential for error.

Therefore, when I use an Imperial drawing, I use Imperial measurements all the way through including my rulers, and vice-versa.

There is one area where I do the conversion and that’s using router bits. The most commonly available router bits here in Australia are Imperial bits. I think that starts with Routers that have either a 1/4” or 1/2” collet. You can get metric adapters, but I don’t like to use them.

Other than that, THINK METRIC, it really doesn’t matter what the Imperial equivalent is.

But, Obi, of course you can’t do this in isolation. Unless there is National agreement to make the switch to metric, I’m afraid going it alone would make you ‘Robinson Crusoe’.
