Calculator guide

Convert signed acceleration between meters per second squared, feet per second squared, standard gravity and Gal. This changes acceleration units without predicting speed or stopping distance.

Formula or method

Output = input × source acceleration factor ÷ destination acceleration factor, through m/s². One ft/s² = 0.3048 m/s²; one standard gravity g₀ = 9.80665 m/s²; one Gal = 0.01 m/s².

How to use this calculator

  1. Enter the Value to convert. The interface starts with 1; replace it with your measurement or quantity. Blank, nonnumeric and out-of-range values cannot produce a result.
  2. Select From unit for the source unit. Match the complete label, including square/cubic units, decimal/binary prefixes or the gallon system when applicable.
  3. Select To unit for the destination unit, then read Converted value with its unit label.
  4. Try the worked example with its stated source and destination units. Results show at most eight fractional digits; very small nonzero values use scientific notation. Check the page limitations before interpreting the output.

Worked example

Select standard gravity (g₀) → meter per second squared (m/s²), then enter 2. Compute 2 × 9.80665 = 19.6133 m/s². A signed input of −1 g₀ gives −9.80665 m/s².

Understanding the result

A negative result preserves the selected axis direction; it is not automatically a statement about slowing down. Standard gravity is a defined reference, not a measured local gravity.

Limitations and assumptions

  • Signed acceleration and zero are accepted. The tool converts one scalar component, not a vector or a time-dependent motion.
  • g₀ is fixed at 9.80665 m/s², not local gravity. Gal is an acceleration unit, not a gallon. No safety threshold or braking model is calculated.

Frequently asked questions

Does g mean grams here?

No. g₀ means standard gravity, an acceleration reference.

Is Gal a volume unit?

No. Capital Gal is the galileo, equal to 0.01 m/s².

Does a negative value mean braking?

Only if it opposes velocity in the chosen direction. A signed component alone does not establish braking.
