📐 How to Use

Choose the unit your figure is already in from the From dropdown, then pick the unit you want in the To dropdown.
Type the number into the value box; the result updates on each keystroke, with a line beneath showing what one source unit equals in the target unit.
Press the swap arrows to reverse the two units, or press Copy to put the converted number on the clipboard.
Click any card in the Common Acceleration Conversions grid to jump to that pair, or open a link under All Acceleration Conversions for a dedicated page with its own conversion table.

❓ Frequently Asked Questions

QHow many m/s² are in 1 g?

One g is 9.80665 m/s². That value is standard gravity, a constant adopted by convention for weights and measures, so the conversion never shifts even though the gravitational acceleration you would actually measure differs a little from place to place.

QWhat is 1 g in ft/s²?

1 g converts to 32.174 ft/s². The calculation divides 9.80665 by 0.3048, the number of meters in a foot, which works out to 32.17404856 and is shortened to 32.2 ft/s² in older engineering texts.

QIs the Gal the same as cm/s²?

Yes. One Gal is 0.01 m/s², which is exactly 1 cm/s², so those two entries convert one to one. Geophysicists prefer the Gal because gravity anomalies are small and are usually quoted in milligals.

QWhat does mph/s measure?

mph/s is a gain of one mile per hour in every second, equal to 0.44704 m/s². Car testing reports acceleration this way because a 0 to 60 mph time is a speed change over seconds rather than an SI figure.

ℹ️ About Acceleration Conversion

Acceleration is the rate at which velocity changes, so every unit is a length divided by a time squared. Several of them hide that structure. The g is not a measurement at all but a ratio to standard gravity, fixed by definition at 9.80665 m/s², while gravity actually felt at sea level varies with latitude. The Gal, named for Galileo and used in gravimetry, is 1 cm/s². Units like mph/s and km/h/s pair a road speed with a second, the form vehicle test figures take.

Eight units are offered here, and every value passes through meters per second squared: the entered figure is multiplied by its own unit's size in m/s², then divided by the target unit's. Results keep four decimal places from 10 upward, six between 1 and 10, and eight below 1, with trailing zeros removed. The arithmetic happens in the page as you type.
