How much acceleration is 655 mph/s?

655 mph/s (29.858g) is extreme acceleration — comparable to an ejection seat firing (12-20g) or a crash-test dummy at moderate impact.

Did you know? Sun surface gravity (28g) is 274 m/s².

The Sun's surface gravity is 274 m/s² — 28 times Earth's. You'd weigh 28x more standing on the Sun.

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: 655 mph/s × 0.0455854 = 29.858 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 29.858 g to mph/s, multiply 29.858 x 21.9369, resulting in 655 mph/s.

655 mph/s is also equal to:

  • 292.81 meter per second squared
  • 960.67 foot per second squared
  • 29281 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.
