NAME
units - unit conversion program
OVERVIEW OF `UNITS'
The `units' program converts quantities expressed in various scales to
their equivalents in other scales. The `units' program can handle mul‐
tiplicative scale changes as well as nonlinear conversions such as
Fahrenheit to Celsius. Temperature conversions require a special syn‐
tax. See the examples below.
The units are defined in an external data file. You can use the exten‐
sive data file that comes with this program, or you can provide your
own data file to suit your needs.
You can use the program interactively with prompts, or you can use it
from the command line.
