Explanation of the knot to foot per second conversion factor
The conversion factor from knot to foot per second (ft/s) is derived by expressing both units in the common base unit of meter per second (m/s). One knot equals 0.514444 m/s and one foot per second equals 0.3048 m/s. Dividing the m/s value for a knot by the m/s value for a foot per second gives the conversion factor.
Definition
A knot is a unit of speed equal to one nautical mile per hour. A foot per second (ft/s) is a unit of speed in the imperial system, measuring the distance traveled in feet over one second. The conversion factor allows for direct translation between these two velocity units.
Principle
The principle is that any two velocity units can be related by expressing each in terms of a common base unit, such as m/s. The ratio of their base-unit equivalents provides the factor to convert one unit to the other.
Assumptions
- The conversion uses the defined equivalences: 1 knot = 0.514444 m/s and 1 ft/s = 0.3048 m/s.
- The conversion is exact based on these defined values.
Cautions
- When performing calculations, round the final result to the precision required by your specific use case.
- The conversion factor 1.68780839895 is a defined ratio, not an experimentally measured value.
