How do you convert from 1 measurement unit to another unit? Say from kilometers to miles.
I can always look it up on that fridge magnet. This one local realtor likes to send me freebies like the fridge magnet with the common conversion factors.
If you don't have a handy fridge magnet, you can try the units command-line utility program.
To install it on a Debian system, enter:
# apt-get install units
# units 60km miles * 37.282272 / 0.0268224
It tells you that 60 kilometers is equivalent to 37.282272 miles.
The second line (beginning with the '/') is somewhat confusing. It is saying, 60 km = 1 / 0.0268224 miles.
Running units in verbose mode makes it clearer.
# units -v 60km miles 60km = 37.282272 miles 60km = (1 / 0.0268224) miles
If you like to put spaces in your search parameters, remember to enclose it with quotes.
# units '60 km' miles * 37.282272 / 0.0268224
If you just want to know the conversion factors, do this:
# units km miles * 0.62137119 / 1.609344
Very quickly, you know:
1 km = 0.62137119 mile, and
1 mile = 1.609344 km.
To many people, installing units and learning all that syntax may be a little too much work.
