About Converting Foot per Days to Kilometer per Days
Foot per Days and Kilometer per Days 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
kilometer per days = foot per days × 0.0003048
This factor comes from each unit's defined relationship to the category's base unit: 1 foot per days equals 0.00000352777777778 base units, and 1 kilometer per days equals 0.0115740740741 base units, so dividing one by the other gives the direct foot per days-to-kilometer per days factor of 0.0003048.
Simple example
1 ft/d × 0.0003048 = 0.0003048 km/d
