What the Acceleration Converter does
Acceleration Converter: 1 m/s² = 0.10197162 g, so multiply a metre per second squared value by 0.10197162 to get standard gravity, or divide to go back. Example: 1 m/s² = 0.10197162 g.
This converter reads Value, From and To and produces Result, How it was calculated and Reverse conversion. Change any input and the output follows immediately.
Unit mistakes are quietly expensive. They have wrecked spacecraft and ruined recipes alike. That is usually what brings students converting units for homework here.
The work is done by JavaScript already loaded in your browser, so your input never crosses the network.
Each field is explained further down, along with the method and a worked example that uses the default values.
What do the Acceleration Converter fields mean?
The Acceleration Converter uses 3 inputs. Because the form arrives filled, the first useful result costs you zero typing.
| Field | What to enter | Default |
|---|---|---|
| Value | required | 1 |
| From | choose from Metre per second squared (m/s²), Centimetre per second squared (gal) (cm/s²), Foot per second squared (ft/s²), Inch per second squared (in/s²), Standard gravity (g) or Kilometre per hour per second (km/(h·s)) | Metre per second squared (m/s²) |
| To | choose from Metre per second squared (m/s²), Centimetre per second squared (gal) (cm/s²), Foot per second squared (ft/s²), Inch per second squared (in/s²), Standard gravity (g) or Kilometre per hour per second (km/(h·s)) | Standard gravity (g) |
How does the Acceleration Converter work?
Both units are converted through acceleration's base unit (m/s²), so any of the 7 units in the dropdowns can be paired in either direction without loss of accuracy.
Every factor here is the defined one, not a textbook approximation. That matters more than it sounds: rounding a factor early is the usual reason two converters disagree in the fourth decimal place.
Worked example
These are the values the Acceleration Converter loads by default, and the result it produces from them. Open the tool above and you will find precisely these figures already in place.
| Value | 1 |
|---|---|
| From | Metre per second squared (m/s²) |
| To | Standard gravity (g) |
| Result | 0.10197162 g |
|---|---|
| How it was calculated | 1 m/s² = 0.10197162 g, so 1 × 0.10197162 = 0.10197162 g |
| Reverse conversion | 9.80665 m/s² (if you meant 1 g) |
Acceleration
Acceleration measures the rate of change of speed, and the metre per second squared (m/s²) is its SI unit, but "standard gravity" (g, exactly 9.80665 m/s² by definition) is the everyday reference point most acceleration figures get compared against.
Worth knowing
- Roller coasters, fighter jet manoeuvres and crash-test data are all commonly described in "g-forces" (multiples of standard gravity) rather than in raw m/s², because g gives a much more intuitive sense of the physical strain involved. "3g" means three times the force of gravity pressing on you.
- A car’s 0-to-60-mph acceleration figure (commonly used in the US) is really describing an average acceleration over that speed range, converting into an equivalent m/s² or g figure that can be compared against, say, aircraft takeoff acceleration or free-fall.
- Standard gravity itself (9.80665 m/s²) is a fixed, internationally agreed reference value, not a live measurement. Actual local gravitational acceleration varies very slightly by location on Earth (a bit less at the equator, a bit more near the poles) due to Earth’s shape and rotation.

How to use it
- Set Value.
- Pick a value for From: the options are Metre per second squared (m/s²), Centimetre per second squared (gal) (cm/s²), Foot per second squared (ft/s²), Inch per second squared (in/s²), Standard gravity (g) or Kilometre per hour per second (km/(h·s)).
- Pick a value for To: the options are Metre per second squared (m/s²), Centimetre per second squared (gal) (cm/s²), Foot per second squared (ft/s²), Inch per second squared (in/s²), Standard gravity (g) or Kilometre per hour per second (km/(h·s)).
- Skip the submit button; there is not one. Editing is enough.
- Check Result, How it was calculated and Reverse conversion on the right.
- Use Copy Link if you want the same setup again later, or Print for a paper copy.
What this tool does not do
- Factors use the internationally agreed definitions; some industries round them differently.
- Repeated conversions compound rounding, so convert once from the original value where you can.
- Intermediate steps are rounded only for display; if you need full precision, work from the source figures.
- The result inherits any error in the inputs without flagging it.
Frequently asked questions
Only Value, From and To. Each field is pre-filled with a sensible default, so you can change one value at a time and watch how the result responds.
With the values loaded when the page opens, result comes out as 0.10197162 g. Nudge one field at a time to see which one the answer is most sensitive to.
