The Unit Conversion calculators allow you to easily convert between
various English and Metric units for length,
area, volume,
weight, temperature,
pressure, and force. Simply choose the appropriate
calculator, clear the calculator of any previous values by clicking the
Clear button, enter the desired value under the desired
unit, and click the Calculate button. The calculator will
select the first non-blank value it encounters, and convert that value to
each of the other units on the calculator's display.
