The next time your
friend Jacques takes you on a ride in his Citroën
deux-chevaux , careening down a narrow, tree-lined French
country road, passing and darting in front of other cars with
centimeters to spare before oncoming traffic speeds by, perhaps
you'll be grateful to know that: (1.) Any speed seems faster
in a deux-chevaux , (2.) Europeans have always been more in
tune with the tolerances of their vehicles than Americans, and (3.)
The 100 kilometers per hour you see on his speedometer is really only
60 miles per hour. Phew! (It's also reassuring that this classic
vehicle can stop on a dime.)
That said, you will
no doubt find it practical, from time to time, to convert weights and
measures between the Imperial and the Metric systems. The table here
will give you the basics (if you're using a calculator), but the
nifty JavaScript calculators below will perform the conversions
directly in your browser in real time! Try them out. Not that the
average tourist will need to convert angstrom units to microns
everyday, but these can be really useful. Let us know what you think!
