How to Convert Standard Gravity to Meter Per Second Squared

1 standard gravity = 9.80665 meters per second squared exact

Meter Per Second Squared = Standard Gravity × 9.80665

Example: 129 g × 9.80665 = 1265.1 m/s²

Reverse Conversion

To convert meters per second squared back to standard gravities:

  • Remember, 1 meter per second squared equals 0.101972 standard gravities.
  • To convert 1265.1 m/s² to g, multiply 1265.1 x 0.101972, resulting in 129 g.

exact This conversion factor is exact by international definition.

129 g is also equal to:

  • 4150.5 foot per second squared
  • 126510 gal
About these units

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

Meter per second squared: SI derived unit of acceleration; change in velocity of 1 meter per second in 1 second.
