How To Convert Meters per Second to Feet per Second
Formula: 1 meter per second = 3.280839895 feet per second.
Example: Convert 5 m/s to ft/s.
5 × 3.280839895 = 16.404199475 ft/s
To convert by hand, you only need one step: multiply your m/s value by 3.280839895. This works because 1 meter equals 3.280839895 feet. Keep the same number of decimals each time if you want consistent results. For quick estimates, you can round the factor, but for exact work, use the full factor shown here.
Quick Answer
1 m/s = 3.280839895 ft/s
- 2 m/s = 6.561679790 ft/s
- 10 m/s = 32.808398950 ft/s
- 20 m/s = 65.616797900 ft/s
Conversion Formula
ft/s = (m/s) × 3.280839895 m/s = (ft/s) ÷ 3.280839895
Recommended (IAU standard): Use the exact meter to foot relationship, where 1 foot = 0.3048 meters exactly, so 1 meter = 3.280839895 feet. That fixed definition makes the factor stable and repeatable.
In simple words, this formula says, “every 1 meter you travel per second is the same as 3.280839895 feet per second.” So you scale up the number when going from m/s to ft/s, because a foot is smaller than a meter.
- Write your speed in m/s.
- Multiply by 3.280839895.
- Keep units as ft/s.
- Round only at the final step if needed.
Meter per second
A meter per second is the SI (metric) unit of speed, meaning how many meters are traveled in one second. Its symbol is m/s.
It comes from the meter and the second, which were standardized through international measurement systems to support science, engineering, and trade. Today it is widely used anywhere SI units are the default.
- Physics problems and classroom science.
- Engineering and lab measurements.
- Weather and wind speed in some countries.
- Vehicle testing and safety research.
- Sports timing and motion analysis.
Foot per second
A foot per second is an imperial and US customary unit of speed, meaning how many feet are traveled in one second. Its symbol is ft/s.
It is based on the foot, a historic length unit used in English speaking regions, paired with the second. It remains common in certain US engineering fields and technical specs.
- US engineering drawings and calculations.
- Ballistics and projectile speed reporting.
- HVAC air speed in ducts.
- Elevator and conveyor speed specs.
- Flow velocity in some industrial settings.
Is this Conversion of Meters per Second To Feet per Second Accurate?
Yes. This conversion is based on fixed, internationally accepted definitions of length. The foot is defined as 0.3048 meters exactly, which makes the relationship 1 meter = 3.280839895 feet consistent and repeatable. Our converter uses this exact factor, the same one used in engineering references and technical standards, so the results are reliable for homework, design work, and real measurements.

Real Life Examples
Here are practical situations where converting m/s to ft/s helps, especially when metric data needs to match US or imperial specifications.
- Walking speed: A comfortable walk might be about 1.5 m/s. That is 1.5 × 3.280839895 = 4.921259843 ft/s, useful when a US report lists hallway traffic speeds in ft/s.
- Running pace in sports testing: If an athlete hits 8 m/s in a sprint, that equals 8 × 3.280839895 = 26.246719160 ft/s, which matches US performance charts that use ft/s.
- Wind tunnel results: A test might set airflow to 12 m/s. Converting gives 12 × 3.280839895 = 39.370078740 ft/s for teams reading imperial airflow targets.
- Elevator specification: An elevator speed of 3 m/s becomes 3 × 3.280839895 = 9.842519685 ft/s, helpful when comparing to older US spec sheets.
- Factory conveyor line: A conveyor moving at 0.5 m/s equals 0.5 × 3.280839895 = 1.640419948 ft/s, which can be used to match US maintenance documentation.
- Robotics and motion control: If a robot arm end effector speed is capped at 2.2 m/s, that is 2.2 × 3.280839895 = 7.217847769 ft/s, useful when a controller interface is set to ft/s.
- Safety testing and impact rigs: A test sled speed of 15 m/s converts to 15 × 3.280839895 = 49.212598425 ft/s, making it easy to compare to US safety datasets.
Quick Tips
- For exact results, multiply by 3.280839895.
- For a fast estimate, multiply by 3.28, then refine if needed.
- Going backwards, divide ft/s by 3.280839895 to get m/s.
- Round at the end, not in the middle, to avoid drift in multi step work.
- If your answer in ft/s is smaller than the m/s value, you likely divided instead of multiplied.
- Write units every time, m/s and ft/s are easy to mix up.
