# Acceleration Units Converter

Acceleration is the ratio change of velocity to change in time - and can be expressed as

a = dv / dt                          (1)

where

a = acceleration (m/s2, ft/s2)

dv = v1 - v0 = change in velocity (m/s, ft/s)

dt = t1 - t0 = time taken to change the velocity (s)

### Online Units Acceleration Calculator

The calculator below can be used to convert between some common acceleration units:

### Example - Acceleration of a Car

A car accelerates from 0 km/h(0 m/s) to 100 km/h(27.8 m/s) in 5 seconds. The acceleration can be calculated by using km/h as the units for velocity:

a = ((100 km/h) - (0 km/h)) (1000 m/km) (1/3600 h/s) / (5 s)

= 5.6 m/s2

The calculation can be simplified by using m/s as the units for velocity:

a = ((27.8 m/s) - (0 km/h)) / (5 s)

= 5.6 m/s2
