The first job, out of college I worked on was metric and no one in the office had metric scales. So we called a company that make scales and asked if they had metric scales, and they said they had both kinds; 6-inch and 12-inch

I have a sticky note at my desk that I wrote for myself;

4 inch = hand

3 hand = foot

3 foot = yard

5 1/2 yard = rod

4 rod = chain

10 chain = furlong

8 furlong = mile

3 mile = league

It is a visual reminder of why I'm glad that I rarely have to worry about any of those units!

There not all that bad.

I do get confused when I have to convert cubic leagues in cubic yards though

I know, I know.  I don't often go off on a crusade, but it was fun.  I've grown up doing conversions in my head, and as long as ole' Uncle Sam refuses to get with the program they're gonna force us to be converting units.  It's not that hard to do.  I just wish they'd set the inch to be exactly 25mm, instead of 25.4mm.  Apparantly during World War I military parts made in USA and shipped over to UK didn't work, because the size of an inch was different.  Both countries in imperial; but they still had conversion problems!  Not sure exactly when it was standardised, but they picked 25.4mm.  I guess (using my handy chart) there being 63360 inches in a mile, if each one was just 0.4mm shorter the whole mile would be 25.344m shorter, and people would start to notice.  Oh well, tough luck to you say I!
