About Converting Millimeter per Seconds to Mile per Seconds
Millimeter per Seconds and Mile per Seconds both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Both are distance divided by time units.
Formula
mile per seconds = millimeter per seconds × 6.213712e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 millimeter per seconds equals 0.001 base units, and 1 mile per seconds equals 1609.344 base units, so dividing one by the other gives the direct millimeter per seconds-to-mile per seconds factor of 6.213712e-7.
Simple example
1 mm/s × 6.213712e-7 = 6.213712e-7 mi/s
1 millimeter per seconds = 6.213712e-7 mile per seconds.
Real-world example
10 mm/s × 6.213712e-7 = 0.0000062137 mi/s
10 millimeter per seconds = 0.0000062137 mile per seconds.
