Why the km/h to ft/s Conversion Factor Holds
The conversion factor between kilometer per hour and foot per second is derived by expressing both units in terms of the common base unit, meter per second.
Definition
The conversion is based on the definitions: 1 km/h = 0.277778 m/s and 1 ft/s = 0.3048 m/s. Dividing the first value by the second gives the forward factor.
Principle
The factor is the ratio of the meter per second equivalents of the two units. This ratio cancels the common base unit, leaving a direct conversion.
Assumptions
- The conversion uses the provided meter per second equivalents for each unit.
- The base unit is meter per second.
Cautions
- The numeric values are exact as provided and should be used without recalculating.
- Round results according to the precision needed for the specific calculation.
