How often do we move decimal points? You sure haven't used the metric system! One of the prime advantages of the metric system is that you don't need fractions. You only have to typeset a few documents containing the lovely 1-3/64" (or is that 1 minus 3 divided by 64 seconds?) type measurements before you realise that the metric system has its advantages! Some questions: How many inches to a mile? How many ounces in a ton? How many cubic inches in a gallon? And if you're east of the Atlantic? Lemmesee, the answers are easy: 5280ft/mile x 12"/ft = 63 360"/mile 16ounces/lb x 2240lbs/ton = 35 840ounces/ton I give up. But whatever the conversion factor is, it's different on the other side of the Atlantic by something like 20%. Now try the equivalent questions for the metric system: mm per km? g per ton? ml per l? What is the mass of a litre of water? West of the Atlantic? Answers: 1 000 000 mm/km 1 000 000 g/ton 1000 ml/l 1 kg, of course And, gee, west of the Atlantic it's the same! > Metrites criticize the English system as arbitrary. But at the end of the > day, I can always find my foot. I dare say your foot may not be an exact twelve inches... Besides, the base unit of the SI system is derived from the circumference of the earth--the circumference over the poles is 40 000 km. > I once tried a 25 meter tower, but found that an 82-foot one worked better. That's only because it sounds higher, thereby lowering your voice by at least three full tones when you tell the station you're working! Now, to relevant stuff: Tool and hardware sizes are much simpler in the metric system. For example, spanners/wrenches/sockets/nuts/bolts are numbered in their mm size, which is an integer. Instead of having to look for a 17/163" tool, you can simply grab a 12. Bolts are similarly numbered by diameter (e.g. an 8 mm bolt). And, best of all, wires are sold by surface area (2 sq. mm) or diameter (1 mm), depending on the application. How much current does a number 22 wire carry anyway? Chris R.
