RR's Unit Converter is an useful tool for any kind of simple or compound unit conversions, using double precision 64-bit format values and operations, with build in dictionary for over 1000 units. Scientist, engineers, students or anyone involved in scientific, financial, archeological or other activities where unit conversions are required will found this program useful. By using a careful developed algorithm, unit conversion factors could be defined between any two units. This feature allows you to use the most precise known unit conversion factor between two units. Therefor, any unit conversions will be performed with high precision. The compound unit feature gives you more flexibility to perform complex transformation and calculation. You could define your own values for fractions. Input fraction: both values, output fraction: bellow value only( above value is the result). RR's Unit Converter comes with a large database of units and a dictionary with definitions for almost all units in the database is included for your convenience. You may even create categories and add your own units to the database. All those features make RR's Unit Converter a powerful tool for all those involved in activities that require any kind of unit conversion.
