Re earlier post: The advantage to Imperial units is they are based on human measurements (inch=roughly the size of a thumb, foot is obvious, yard is the length of an arm) and are therefore easy to visualize.
I don't know what size your body is, but my thumbs are definitely over 2 inches long, and my arms are about 5-6 inches shorter than 1 yard, hand and fingers included. Only the foot seems reasonably accurate, but only if you have big feet.

An inch is roughly the WIDTH of your thumb, not the length, a yard is the length of an outstretched arm to your nose (when looking straight ahead); although a meter just involves turning your head away from said arm.
Now, I think we should bring back the cubit... defined as the length from elbow to fingertips but those french 'standardised' it to 18 inches.
By the way, 12 inches in a foot is easy - the word inch comes from the latin uncae meaning 'a twelfth'
Also, some primary schools are starting to teach kids both systems. I was only ever taught metric, but still use imperial where it is good - if you want an approximate length, inches are perfect - 10 inches vs 250mm.
And there is nothing wrong with having something 1 meter 3 inches long.
Let me also point out that cm is not an SI unit - only 10^3 is included so it goes mm -> m, the cm was only devised for teaching because the young can't come with the huge gap... you don't get that problem with imperial.
Now, what's wrong with awg for measuring wire thicknesses?
And why do we have to measure frequency in Hertz? Cycles per second tells you exactly what is happening!
The comment about KW vs BHP - KW is only for use in electrical situations, the metric for BHP (ie engines) is the PS (or Pferdestärke - german for horse strength) - 1.013PS=1BHP - british horses are stronger than german ones, so lets keep the british horse power!!!
Lets have imperial for where it relates to the body (esp pints), metric where it relates to the french - 9mm pistols and 200mm cannons spring to mind.
For the record, I'm 24 cycles round the sun old.
