Mile per Hour (mph) to Knot Conversion Factor
This conversion factor is derived by expressing both units of speed in the common base unit of meter per second (m/s) and then taking the ratio of their equivalent values. The factor accounts for the difference between a mile per hour and a nautical mile per hour.
Definition
A knot is a unit of speed equivalent to one nautical mile per hour. A mile per hour (mph) is a unit of speed equivalent to one statute mile per hour.
Principle
The conversion factor is the ratio of the value of 1 mph expressed in m/s to the value of 1 knot expressed in m/s. The shared base unit cancels, leaving a dimensionless factor.
Assumptions
- The conversion uses the standard defined values: 1 mph = 0.44704 m/s and 1 knot = 0.514444 m/s.
- The base unit for both speed measures is the meter per second (m/s).
Cautions
- The factor is based on exact defined conversions for each unit to m/s.
- Result precision depends on the input precision and the number of decimal places used in the calculation.
