How much acceleration is 1 mph/s?

1 mph/s (0.046g) is a very gentle acceleration — comparable to a car creeping forward from idle or a train departing a station.

How to Convert Mile Per Hour Per Second to Standard Gravity

1 mile per hour per second = 0.0455854 standard gravities

Standard Gravity = Mile Per Hour Per Second × 0.0455854

Example: 1 mph/s × 0.0455854 = 0.045585 g

Reverse Conversion

To convert standard gravities back to miles per hour per second:

  • Remember, 1 standard gravity equals 21.9369 miles per hour per second.
  • To convert 0.045585 g to mph/s, multiply 0.045585 x 21.9369, resulting in 1 mph/s.

1 mph/s is also equal to:

  • 0.44704 meter per second squared
  • 1.4667 foot per second squared
  • 44.704 gal
About these units

Mile per hour per second: Practical acceleration unit; change in velocity of 1 mph in 1 second.

Standard gravity: Nominal gravitational acceleration at Earth's surface, defined as exactly 9.80665 m/s².
