What Is This Tool?

This tool converts speed measurements from foot per second (ft/s), a US customary and Imperial unit, to millimeter per second (mm/s), a metric unit. It helps translate speeds used in various engineering and physics contexts into a finer metric scale.

How to Use This Tool?

  • Enter the speed value in foot per second (ft/s).
  • Select foot/second as the input unit and millimeter/second as the output unit.
  • Click the convert button to get the result in millimeter/second.
  • Use the converted values for engineering, manufacturing, or monitoring tasks.

Key Features

  • Converts speeds from foot/second to millimeter/second accurately.
  • Supports applications in ballistics, HVAC, and precision motion control.
  • Easy to use with a clear input and output interface.
  • Browser-based and accessible without software installation.

Examples

  • 2 ft/s converts to 609.6 mm/s.
  • 0.5 ft/s converts to 152.4 mm/s.

Common Use Cases

  • Specifying projectile or muzzle velocities in ballistics.
  • Reporting air or fluid velocities in HVAC and wind tunnel testing.
  • Setting feed rates for 3D printer heads and linear actuators.
  • Monitoring vibration velocities in rotating machinery.
  • Performing precise physics and engineering speed calculations.

Tips & Best Practices

  • Double-check units before converting to maintain consistency.
  • Be mindful of numerical precision when working with very high or low speeds.
  • Use this conversion for applications requiring detailed speed resolution.
  • Ensure your input values are accurate to avoid compounding errors.

Limitations

  • Conversion between foot/second and millimeter/second spans several orders of magnitude, requiring attention to precision.
  • Foot/second is based on US customary and Imperial units, while millimeter/second belongs to the metric system.
  • Users should confirm unit consistency during calculations to prevent errors.

Frequently Asked Questions

What is the exact conversion rate from foot/second to millimeter/second?
1 foot/second equals exactly 304.8 millimeter/second.

In which fields is converting ft/s to mm/s commonly used?
It is widely used in ballistics, HVAC engineering, precision motion control, manufacturing automation, and machinery condition monitoring.

Why should I be careful about precision when converting these units?
Because the units differ by several orders of magnitude, rounding errors can affect accuracy when converting very high or low speed values.

Key Terminology

Foot/second [ft/s]
A speed unit in the US customary and Imperial systems representing one foot traveled in one second; exactly 0.3048 meters per second.
Millimeter/second [mm/s]
A derived metric speed unit equal to one millimeter traveled in one second, commonly used for low velocities and precise motion control.
Conversion Rate
The factor used to translate a speed value from foot/second to millimeter/second, which is 304.8.
