About Converting Kilometer per Seconds to Foot per Hours
Kilometer per Seconds and Foot per Hours 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
foot per hours = kilometer per seconds × 11811023.622
This factor comes from each unit's defined relationship to the category's base unit: 1 kilometer per seconds equals 1000 base units, and 1 foot per hours equals 0.0000846666666667 base units, so dividing one by the other gives the direct kilometer per seconds-to-foot per hours factor of 11811023.622.
Simple example
1 km/s × 11811023.62 = 11,811,023.62 ft/h
