What this calculator does
G-Force from Acceleration works out how many g's a change in velocity over time represents, relative to standard gravity. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
Formulag-force = (v₁ − v₀) / (t × g), g = 9.80665 m/s²
The inputs explained
| Field | What to enter |
|---|---|
| Initial velocity (m/s) | A number, measured in m/s. Starts at 0. |
| Final velocity (m/s) | A number, measured in m/s. Starts at 28. |
| Time interval (s) | A number, measured in s. Starts at 3. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with initial velocity
Every other input is held at the calculator’s starting values while initial velocity varies. Select any row to load that scenario into the calculator.
