About Converting Mile per Seconds to ft/s
Mile per Seconds and ft/s both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Distance divided by time, and feet per second.
Formula
ft/s = mile per seconds × 5280
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 ft/s equals 0.3048 base units, so dividing one by the other gives the direct mile per seconds-to-ft/s factor of 5280.
Simple example
1 mi/s × 5280 = 5,280 ft/s
1 mile per seconds = 5,280 ft/s.
Real-world example
10 mi/s × 5280 = 52,800 ft/s
10 mile per seconds = 52,800 ft/s.
