Unit definition
Metres per second (m/s) One metres per second equals 1 metre per second.
Unit history
Metres per second 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 m/s to metre per second.
3. Convert the base value to ft/s and apply your display precision.
Important
Mach uses 343 m/s, a representative dry-air value near 20 °C.
Understand the result before using it
Metres per second to Feet per second converts a value measured in Metres per second (m/s) into the equivalent value in Feet per second (ft/s). 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 × 1 ÷ 0.3048
Assumptions
- Metres per second and Feet per second represent the same speed quantity.
- The input is expressed in m/s; the output is expressed in ft/s.
- Mach uses 343 m/s, a representative dry-air value near 20 °C.
Worked example
1 m/s ≈ 3.28083989501 ft/s. 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 m/s measurement in a document that expects ft/s.
- Compare a metres per second value with a value reported in feet per second.
- Check the m/s to ft/s 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.

Questions about this calculation
How do I convert Metres per second to Feet per second?
result = input × 1 ÷ 0.3048. Input is in m/s; result is in ft/s. 1 m/s ≈ 3.28083989501 ft/s. The displayed digits may be rounded.
What is 1 m/s in ft/s?
1 m/s ≈ 3.28083989501 ft/s. The displayed digits may be rounded.
Can I reverse the m/s to ft/s conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts ft/s back to m/s.
Is the Metres per second to Feet per second result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
