[L T⁻²]

Where:

* L represents length (or distance)

* T represents time

This means that acceleration is measured in units of length per unit time squared.

Common units of acceleration:

* Meters per second squared (m/s²)

* Feet per second squared (ft/s²)

* Centimeters per second squared (cm/s²)

* Kilometers per hour squared (km/h²)

Derivation of the dimensions:

Acceleration is defined as the rate of change of velocity with respect to time. Velocity has dimensions of [L T⁻¹] (length per unit time). Therefore, acceleration, which is the change in velocity over time, has dimensions of:

[L T⁻¹] / [T] = [L T⁻²]
