Unit definition
Gal (Gal) One gal equals 0.01 metre per second squared.
Unit history
Gal is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert Gal to metre per second squared.
3. Convert the base value to ft/s² and apply your display precision.
Understand the result before using it
Gal to Feet per second squared converts a value measured in Gal (Gal) into the equivalent value in Feet per second squared (ft/s²). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 0.01 ÷ 0.3048
Assumptions
- Gal and Feet per second squared represent the same acceleration quantity.
- The input is expressed in Gal; the output is expressed in ft/s².
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 Gal = 0.0328083989501 ft/s². For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a Gal measurement in a document that expects ft/s².
- Compare a gal value with a value reported in feet per second squared.
- Check the Gal-to-ft/s² arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Mach varies with the local speed of sound; this tool uses the representative condition stated beside the converter.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.
