GNU Units is a cross-platform computer program for conversion of units of quantities. It has a database of measurement units , including esoteric and historical units. This for instance allows conversion of velocities specified in furlongs per fortnight , and pressures specified in tons per acre . Output units are checked for consistency with the input, allowing verification of conversion of complex expressions.
