Unit definition
Feet per second squared (ft/s²) One feet per second squared equals 0.3048 metre per second squared.
Unit history
Feet per second squared 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 ft/s² to metre per second squared.
3. Convert the base value to cm/s² and apply your display precision.
Understand the result before using it
Feet per second squared to Centimetres per second squared converts a value measured in Feet per second squared (ft/s²) into the equivalent value in Centimetres per second squared (cm/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 × 0.3048 ÷ 0.01
Assumptions
- Feet per second squared and Centimetres per second squared represent the same acceleration quantity.
- The input is expressed in ft/s²; the output is expressed in cm/s².
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 ft/s² = 30.48 cm/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 ft/s² measurement in a document that expects cm/s².
- Compare a feet per second squared value with a value reported in centimetres per second squared.
- Check the ft/s²-to-cm/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.
