How much acceleration is 685 g?

685 g (685g) is violent acceleration — comparable to a bullet being fired or a high-g centrifuge test.

How to Convert Standard Gravity to Mile Per Hour Per Second

1 standard gravity = 21.9369 miles per hour per second

Mile Per Hour Per Second = Standard Gravity × 21.9369

Example: 685 g × 21.9369 = 15027 mph/s

Reverse Conversion

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

  • Remember, 1 mile per hour per second equals 0.0455854 standard gravities.
  • To convert 15027 mph/s to g, multiply 15027 x 0.0455854, resulting in 685 g.

685 g is also equal to:

  • 6717.6 meter per second squared
  • 22039 foot per second squared
  • 671760 gal
About these units

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

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