About Converting Mile per Seconds to Millimeter per Seconds
Mile per Seconds and Millimeter 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
millimeter per seconds = mile per seconds × 1609344
This factor comes from each unit's defined relationship to the category's base unit: 1 mile per seconds equals 1609.344 base units, and 1 millimeter per seconds equals 0.001 base units, so dividing one by the other gives the direct mile per seconds-to-millimeter per seconds factor of 1609344.
Simple example
1 mi/s × 1609344 = 1,609,344 mm/s
1 mile per seconds = 1,609,344 millimeter per seconds.
Real-world example
10 mi/s × 1609344 = 16,093,440 mm/s
10 mile per seconds = 16,093,440 millimeter per seconds.
