About Converting Kilometer per Days to ft/s
Kilometer per Days 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 = kilometer per days × 0.0379726839701
This factor comes from each unit's defined relationship to the category's base unit: 1 kilometer per days equals 0.0115740740741 base units, and 1 ft/s equals 0.3048 base units, so dividing one by the other gives the direct kilometer per days-to-ft/s factor of 0.0379726839701.
Simple example
1 km/d × 0.03797268397 = 0.037972684 ft/s
1 kilometer per days = 0.037972684 ft/s.
Real-world example
10 km/d × 0.03797268397 = 0.3797268397 ft/s
10 kilometer per days = 0.3797268397 ft/s.
