PPS. Darned Babylonians... we still use base 60. Why 360 degrees.....

2π radians == 360 degrees is okay; you want a circle nicely divisible by 3 and 4. And by coincidence the year is about 360 days. But using 60 for the subdivisions of the degree ... no! Scrap the minutes and seconds, and use tenths, hundredths, etc. of degrees.

And the meter should have originally been defined as 1/9M of the distance from pole to equator, not 1/10M. Then a degree of latitude would be 100 km, and the knot would be 1 km/hr, usable on land and sea.

Uh, before that, you have to get rid of seconds, minutes, hours and redefine into 10 hours/day, either 10 minutes or 100 minutes/hour, and either 10s or 100 seconds/minute. And if 10minutes, 10 seconds are used, then you will need to make up a new time name at power of 10 past seconds. Probably would not happen. So, 10h, 100min, 100seconds. Problem, 10 hours/day doesn't work well and probably would have to turn that into 20 hours/day.

This changes definition of kilometer by the way.... as that is defined by light speed/second. Definition of second just changed...

Right now there are approximately 85,000seconds in a day.

60*60*24.

New "day" would be 100*100* either 10hours or 20 hours, so either 100,000 seconds/day or 200,000 seconds/day. Either way, kilometer is getting shorter, or MUCH longer, if someone kept definition of meter the same and made up something past seconds. If 10 hour day, then kilometer would be ~1/7th shorter than currently. If 20 hour day, a kilometer would be ~4.5/7ths shorter, or roughly a "foot", a MUCH more useable number as it now would approximately be the length of your foot...

A mile would become 1000 new "feet", so all of our "speeds" would increase and people would have larger ego's as they are now moving so much "faster"...

NO, circles do not need to be divisible by 3. 4 only. For quadrants. 100 degrees works just fine in that case. 25 degrees/quadrant and 100minutes/degree and 100seconds/minute.

I believe the French tried it in the 18th century but too many things changed and it turned into mass confusion.[/quote]
