ConvertAll

A comprehensive unit conversion program.

With ConvertAll, you can combine the units any way you want. If you want to convert from inches per decade, that's fine. Or from meter-pounds. Or from cubic nautical miles. The units don't have to make sense to anyone else.

Some of ConvertAll Features Units may be combined with the "*" and "/" operators. Units may be raised to powers (squared, cubed, etc.) with the "^" operator. Units in the denominator may be grouped with parenthesis. Units with non-linear scales, such as temperature, can also be converted. Recently used unit combinations may be picked from a menu. Numbers may be entered on either the "From" or the "To" units side, for conversions in both directions. Basic mathematical expressions may be entered in place of numbers. Options control the formatting of numerical results. The unit data includes over 500 units. Conversions between various number bases (decimal, hexadecimal, octal and binary) can be done in a separate dialog window. A decimal number can be converted to fractional numbers in a separate dialog window. Command line options are available to do conversions without the GUI.
