I have a full set of metric sockets... with 1/4, 3/8 and 1/2 inch drive. A

friend showed me his new 23mm wrench, and it measured exactly 11 inches

long. I can get to anywhere "metric" measurements are standard by flying at

flight levels measured in thousands of feet and at speeds measured in knots.

Dunno about recent semiconductors, but historically IC lead spacing has been

specified in thousandths of an inch. How much of the imperial unit system

are you using? Are construction materials there measured entirely in metric,

and your ceilings 2.44m high?

This is one of my pet peeves: the French created several weird "base 10"

systems in the aftermath of the revolution, including a calendar with ten

months (today is the first day of Floreal CCXIV) and a day with ten hours,

but it seems only the metric system caught on. (Although renaming holidays

after vegetables and such instead of saints has an odd appeal...) It really

is a terrible idea, compounding the Romans' mistake of using a base 10

number system. Base 12 is far more useful, since a dozen can be divided by

2, 3, 4, or 6. 10 can only be divided by 2 and 5. That problem carries over

into mechanical engineering, where measurements are divided by 3 or 4 more

often than they are divided by 5.

It could have been worse, I guess - it could have been base 11. Anyway, the

world would be a better place if the French republic had worked to replace

the base 10 number system with base 12, then to correct the oddities (like

the mile) to match.

Why is it that odometers are marked in tenths of a mile (at least the

trip odometers are; total-distance ones seem to have dropped the

fractions), but highway signs are in quarters and halves of a mile?

Because we have yet to find intelligent life in the universe. Thank

goodness I have an English/metric crescent wrench.

I occasionally drive between Jacksonville, FL, and the DC suburbs in

Maryland, and these are the only times when I generally drive in the

75-80 mph range (not counting when I'm stationary on the Capitol

Beltway). On these trips, I average only 41-43 MPG, as compared to my

usual 46-48. I usually fill up when the digital gauge gets down to one

tick, taking on 9-10 gallons. So... that's 360-425 miles per tank.

My answer for an 03 Prius, NHW11 model:

http://hiwaay.net/~bzwilson/prius/

On a recent 14 hour trip to Kansas City and the return, I made it a

point to pull off and take a break every 2-3 hours. Because of the fuel

efficiency, I stopped shopping for gas beyond driving past the first

cluster of gas stations at the exits.

The current 06 Prius gets better performance:
