Conversion between foot per second and mile per hour
The conversion factor between foot per second (ft/s) and mile per hour (mph) is derived by expressing both units in terms of the same base unit, meter per second (m/s).
Definition
Foot per second (ft/s) and mile per hour (mph) are both imperial units of speed. The conversion factor is a fixed ratio between these units.
Principle
The principle is to rewrite each unit in a common base unit, meter per second (m/s). One foot per second equals 0.3048 m/s, and one mile per hour equals 0.44704 m/s. Dividing the value for ft/s by the value for mph yields the forward conversion factor.
Assumptions
- The conversion uses the exact definitions: 1 ft/s = 0.3048 m/s and 1 mph = 0.44704 m/s.
- The conversion factor is a fixed mathematical ratio.
Cautions
- The provided numbers are precise; rounding may be needed for practical use.
- This conversion is for speed units only and does not account for factors like measurement error.
