SpeedUnit enum

Represents units of speed.

This enum implements the LinearUnit interface to provide conversion capabilities and a display symbol for each speed unit. All conversion factors are pre-calculated in the constructor relative to Meter per Second (m/s).

Values

meterPerSecond → const SpeedUnit: Meter per second (m/s), the SI derived unit of speed.

const SpeedUnit(1, 'm/s')
kilometerPerSecond → const SpeedUnit: Kilometer per second (km/s), a common unit in scientific contexts like astronomy.

const SpeedUnit(SpeedFactors.mpsPerKps, 'km/s')
kilometerPerHour → const SpeedUnit: Kilometer per hour (km/h), a common unit for road vehicle speed.

const SpeedUnit(SpeedFactors.mpsPerKmh, 'km/h')
milePerHour → const SpeedUnit: Mile per hour (mph), a common unit for road vehicle speed in some countries.

const SpeedUnit(SpeedFactors.mpsPerMph, 'mph')
knot → const SpeedUnit: Knot (kn), a unit of speed equal to one nautical mile per hour. Commonly used in maritime and aviation contexts.

const SpeedUnit(SpeedFactors.mpsPerKnot, 'kn')
footPerSecond → const SpeedUnit: Foot per second (ft/s), used in some engineering contexts.

const SpeedUnit(SpeedFactors.mpsPerFps, 'ft/s')
