Acceleration.

Convert g₀ to m/s², or pick any of the 5 units in the menus. Type in either box and the other follows. Metres per second squared, and the g everyone quotes — standard gravity is a defined 9.806 65 m/s², not the gravity where you are standing.

Definitions

  • Standard gravity, g₀, is defined as exactly 9.806 65 m/s². It is a fixed reference value, not the gravity measured at your location.
  • The metre per second squared is the SI unit of acceleration.
  • Standard gravity g₀ is defined as exactly 9.80665 m/s². Local gravitational acceleration varies with latitude and altitude.
  • Every unit in the menus is exact by definition, so the only rounding on this page is the one you choose for the display.

How it works

Every value is converted into metres per second squared and then back out into the unit you asked for. One route covers every pairing in the menus, so an unusual combination is no less accurate than a common one, and adding a unit affects only that unit.

Both boxes are live. Whichever one you last typed in is the source, changing either menu recalculates straight away, and Swap exchanges the units and the values so the number you are reading stays where you are looking.

Display precision sets a maximum number of significant figures and trims trailing zeroes, so it changes what you see and never what was calculated. The editable box always holds a plain number at full working precision, so you can carry on from either side.

Common questions this answers: how many metres per second squared in a standard gravity (9.80665), how many standard gravities in a metre per second squared (0.101972), and what 1 g₀ is in metres per second squared (9.80665 m/s²).
