Acceleration Converter

The Acceleration Converter changes a single acceleration figure into every common unit at once, so you never have to remember an awkward factor again.

Enter a value, pick the unit it is written in, and the tool shows the equivalent in metres per second squared, centimetres per second squared (the gal, used in geophysics), feet per second squared, inches per second squared, multiples of standard gravity g, and the practical automotive rates of km/h per second and mph per second.

Acceleration crops up everywhere from physics homework and engineering specs to car performance figures and accelerometer datasheets, and those fields each favour a different unit.

A vibration report may quote g, a vehicle test sheet talks in mph per second, and a textbook problem is set in m/s².

Converting between them by hand means juggling 9.80665, 0.3048 and unit-time arithmetic; this tool does it instantly and lets you copy any result.

Negative values are accepted so you can express deceleration or braking, and every figure is rounded to remove floating-point noise while staying precise.

All calculation happens locally in your browser — nothing is uploaded — so it is private and works offline once the page has loaded.
