About Converting Kilometer per Seconds to Foot per Days
Kilometer per Seconds and Foot 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
foot per days = kilometer per seconds × 283464566.929
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 days equals 0.00000352777777778 base units, so dividing one by the other gives the direct kilometer per seconds-to-foot per days factor of 283464566.929.
Simple example
