Conversion of units
The equations stated above are based on the SI-unit system. If parameters are
known in other units, they must be converted into a SI unit before entering the
equations. The result will be in an SI unit.
After the calculation the result may be converted to the desired unit. Conversion
of units may be performed, using the equations stated below:
