Acceleration Converter

What is the Acceleration Converter?

The Acceleration Converter turns a single acceleration value into every other common unit at once. Enter an amount, choose the unit it's measured in, and instantly see the equivalent in meters per second squared (m/s²), Galileo (Gal), feet per second squared (ft/s²), inches per second squared (in/s²), and standard gravity (g). It's built for engineers, physics students, and anyone working with motion, gravity, or vibration data who needs a fast, reliable unit lookup instead of hunting for conversion formulas.

Supported units

• Meter per Second Squared (m/s²) — the SI derived unit of acceleration, and the base unit this tool converts through internally.
• Galileo (Gal) — a CGS unit used mainly in geodesy and gravimetry, where 1 Gal = 1 cm/s² = 0.01 m/s².
• Foot per Second Squared (ft/s²) — the imperial equivalent of m/s², common in US engineering and ballistics work.
• Inch per Second Squared (in/s²) — a smaller imperial unit, useful for precision motion and vibration measurements.
• Standard Gravity (g) — the conventional value of Earth's gravitational acceleration (9.80665 m/s²), widely used to express g-forces in aerospace, automotive, and biomechanics contexts.

How to use it

1. Enter the acceleration value you want to convert in the Amount field.
2. Select the unit that value is currently measured in from the Unit dropdown.
3. Optionally adjust Decimal precision (0–10 decimals) to control how many digits appear in the results.
4. The table below updates automatically, showing your value converted into all five supported units.
5. Use the copy or download buttons on the results table to grab the full conversion table as CSV.

The conversion updates live as you type or change options — there's no separate "Convert" button to press.

How the conversion works

Every unit is converted through meters per second squared as a common base: your input is first converted to m/s² using that unit's conversion factor, then from m/s² into each of the five output units. This two-step approach (rather than direct pairwise formulas) keeps the math simple and consistent no matter which unit you start from.

For very large or very small results, values are shown in exponential notation to preserve precision; otherwise, results are shown as fixed-decimal numbers with trailing zeros trimmed.

Why is standard gravity a unit of acceleration?

Standard gravity (g) is technically a fixed reference acceleration — defined by convention as exactly 9.80665 m/s² — rather than a variable measured quantity. It's included here because it's the standard way to express g-forces (e.g., "3g" in a roller coaster or centrifuge) and to relate weight-based measurements to acceleration.

Is this conversion accurate?

Yes. All conversion factors are exact, standards-based values (for example, 1 standard gravity = 9.80665 m/s² exactly, per the international definition). Results are only rounded for display according to the decimal precision you select — the underlying math always uses full floating-point precision.
