Magnitude of Acceleration Calculator (Vector Length)

Find the magnitude of an acceleration vector three ways: from 2D components, 3D components, or change in velocity over time. It auto-converts to several units.

How to use
  1. Pick the mode: 2D components, 3D components, or Δv over time.
  2. Enter the component values or the velocity change and time.
For study and estimation. Verify against authoritative data before relying on a result.

Common questions

How do I find the magnitude from components?

Take the square root of the sum of the squared components. In 2D that is the square root of ax² plus ay².

What is acceleration measured in?

Usually metres per second squared. The calculator can also show g-force and other units.
