Write something like 180 lb > kg into the Input field and press Enter to calculate!

Write the query into the Input field. A query consists of 4 or 5 pieces separated by spaces. For example, to convert 180 pounds into kilograms, type 180 lb > kg and press Enter. The result will be shown in the Output field. If the specified units are found in several unit categories, multiple results will be returned.

There exist units which have no well-established symbol, such as the nautical mile. In such case one must spell out the full name (not all units are recognized this way, though). Any name or abbreviation containing spaces must be placed in single quotes: 1 'US gallon' > 'US pint'.

Instead of a numerical value one can also insert a mathematical expression wrapped in single quotes: '15.4+3.9' psi > kgf/cm2.

The default display precision is 6 significant digits. To change the number of digits to 8 (for example), add #8 to the end of the query.

The program implements a generic unit converter. One can defne even non-linear relations, which are not, rigorously speaking, unit conversions, but arbitrary relations between two numerical quantities. For instance, type 5800 K > nm. You can download the program for offline use or to add more exotic units .
