I think if you memorize basic units of metric to imperial, conversion becomes a lot easier. For example, 100mm is about 4". Therefore, 25mm is about an inch and 300mm is about a foot. This helps with quick reference.

I used a metric ID/OD grinder for a while and that was a real treat... until you converted! What a pain!

I orriginally started learning Standard in school and then learned metric and totally ignored english system. In canmada we do you both all the time and in building I go back and forth. Of course don't forget, a yard in Canada is different than a yard in the US which is different than a yard in the UK. Not much but slightly different in length so when real accuracy is needed it can be a problem. Likewise a Canadian Gallon is not the same size as an american Gallon. As well, in the building industry we still talk about everything in feet and inches but some of our 4'X 8' sheets are not actually 4'x8' they are a metric measurement that is really close. In the end for what we do I figure it doesn't mattet which we use.

Not using the metric system is anti-semetric, can't we all just get along! (sorry can't take credit for that, it was said to me by a drunken customer years ago and I have not stopped laughing)

Evan, your shop must be a weird and wonderful world! Now, back to the original topic--Imperial metrics and thousandths of an itch!

So why is a circle divided into degrees rather than hundredths?

thats cause circles are hot!!
as for the thousands of an itch stew-mac has a topical cream for that.

I'm glad you "caught" that Evan. There's a lot of funny things said accidentally on these posts. Speaking of which, this thread should have been buried weeks ago.

Now that I ate all the Christmas Stuffing, I am watching my weight. So I may have to divide my pies (circles) into hundredths of degrees
