How To Convert Feet per Second to Meters per Second
Formula: 1 ft/s = 0.3048 m/s
Example: Convert 20 ft/s to m/s.
20 × 0.3048 = 6.096 m/s
To convert manually, you multiply the speed in feet per second by 0.3048. This works because 1 foot equals exactly 0.3048 meters. The “per second” part stays the same on both sides. If you need a quick estimate, you can use 0.3, then refine it.
Quick Answer
1 ft/s = 0.3048 m/s
- 5 ft/s = 1.524 m/s
- 30 ft/s = 9.144 m/s
- 88 ft/s = 26.8224 m/s
Conversion Formula
m/s = (ft/s) × 0.3048
Recommended (SI exact conversion): 1 foot = 0.3048 meter (exact). So every 1 ft/s becomes 0.3048 m/s with no measurement ambiguity in the factor itself.
In simple words, this formula says, “take your speed in feet per second and scale it down to meters per second,” because a meter is longer than a foot. You are not changing time units, only the length unit.
- Write the value in ft/s.
- Multiply by 0.3048.
- Keep the unit as m/s.
- Round only at the end if needed.
Foot per Second
A foot per second is a speed unit that means moving 1 foot in 1 second. Symbol: ft/s.
It comes from the foot, a traditional length unit used in the US and other systems before global SI standard use. In modern work, it is tied to the international foot, defined exactly from the meter.
- Airflow and duct air speed in US building plans
- Conveyor belt speeds in factories using imperial units
- Water flow speed in channels and small rivers (US reports)
- Sports tracking in some US coaching tools
- Engineering field notes where feet are the working unit
Meter per Second
A meter per second is the SI speed unit that means moving 1 meter in 1 second. Symbol: m/s.
It is based on the meter, the modern international standard for length. It is widely used in science, weather, transport, and engineering because it matches the SI system.
- Physics problems and lab measurements
- Wind speed in scientific and many weather reports
- Vehicle and bike speed calculations in engineering
- Robotics and motion control settings
- Fluid speed in research and simulations
Is this Conversion of Feet per Second To Meters per Second Accurate?
Yes. This conversion is based on the exact international definition of the foot, where 1 foot = 0.3048 meter exactly. Because the factor is fixed by standard, the conversion from ft/s to m/s is mathematically exact, and any small difference you may see comes only from rounding the final decimal display. Our team follows published unit standards and consistent rounding rules. For more details, see our accuracy standards.
Real Life Examples
Feet per second is common in US-focused work, while meters per second is common in science and global engineering. Here are realistic conversions you can actually use.
- Walking pace: A relaxed walk might be about 4 ft/s. That is 4 × 0.3048 = 1.2192 m/s, useful for estimating how long it takes to cross a hallway or sidewalk.
- Running sprint speed: A fast short sprint can reach around 25 ft/s. That equals 7.62 m/s, which helps when comparing to track and field speed data in SI units.
- Baseball pitch speed (rough motion speed near release): If a measured motion segment is 120 ft/s, it converts to 36.576 m/s, helpful for physics calculations like time of flight.
- River current: A current of 3 ft/s becomes 0.9144 m/s, useful for safety planning and estimating drift distance.
- Factory conveyor line: A conveyor set to 10 ft/s is 3.048 m/s, helpful when matching equipment specs that use SI units.
- Indoor wind tunnel or fan test: An air speed reading of 15 ft/s equals 4.572 m/s, useful for comparing to lab targets written in m/s.
- Elevator or lift motion: A lift moving at 5 ft/s is moving at 1.524 m/s, helpful for comfort and safety checks.
Quick Tips
- Exact rule: multiply ft/s by 0.3048.
- Mental math: multiply by 0.3 for a fast estimate, then adjust slightly upward.
- Easy split: 0.3048 = 0.3 + 0.0048, so add 0.48% of (ft/s) after the 0.3 part.
- To go backwards (m/s to ft/s), multiply by 3.28084.
- Round at the end, not in the middle, to avoid drift.
- If you see ft/s values from sensors, check if they output rounded feet, then your final m/s will inherit that rounding.
