Information:

  • The SI standard unit for acceleration is meters per square second (m/s²).
  • G, gn, and grav typically refer to standard gravity (approx. 9.80665 m/s²).
  • Gal (Galileo) is a unit where 1 Gal = 0.01 m/s². Centigal (cGal) is 0.01 Gal.
Conversion Details & Formula

Formula:

Result (mph/s) = Input Value (ft/s²) × 0.6818182

The conversion factor is derived from SI base unit conversions: (0.3048 / 0.44704)

Unit Relationship:

  • 1 ft/s² (Foot/Square Second) = 0.6818182 mph/s (Mile per hour per second)
  • 1 mph/s (Mile per hour per second) = 1.4666667 ft/s² (Foot/Square Second)

Equivalence to SI Base Unit (m/s²):

  • 1 ft/s² (Foot/Square Second) = 0.3048 m/s²
  • 1 mph/s (Mile per hour per second) = 0.44704 m/s²
