How the conversion works
This pair is not a multiplication. The two units move in opposite directions or through an angle, so the converter above computes it rather than applying a single factor.
At least one of these units is measured or conventional rather than defined, so the last digits of any answer carry that uncertainty.
METHOD AND SOURCES
Where the conversion factors come from
Results are calculated from the unit definitions stored in the converter, not copied from a lookup table. For exact units, every value in the table follows from the same factor shown in the formula above.
