What Is This Tool?

This converter allows users to transform speed values from foot/hour (ft/h), an imperial unit used for very slow velocities, into millimeter/second (mm/s), a metric unit widely used in precise engineering and scientific applications. It simplifies the process of converting slow speed measurements into compatible metric terms.

How to Use This Tool?

  • Enter the speed value in foot/hour (ft/h) into the input field
  • Select foot/hour as the source unit and millimeter/second as the target unit
  • Click the convert button to calculate the result
  • View the converted speed in millimeter/second (mm/s)
  • Use the output for engineering, geological, or monitoring purposes

Key Features

  • Converts foot/hour speeds precisely into millimeter/second units
  • Supports very low velocity measurements common in geology and industrial automation
  • Browser-based tool requiring no installation
  • Clear input and output fields for straightforward usage
  • Provides conversion examples for user guidance

Examples

  • Convert 10 ft/h: 10 × 0.0846666667 = 0.846666667 mm/s
  • Convert 50 ft/h: 50 × 0.0846666667 = 4.233333335 mm/s

Common Use Cases

  • Describing slow geological or glacial movement rates over hours or days
  • Specifying slow actuator or conveyor speeds in industrial motion control
  • Reporting settlement or drift rates in structural monitoring with hourly measurements
  • Translating imperial slow speeds into metric units for precise engineering applications
  • Setting feed rates for linear actuators and 3D printer heads with sub-millimeter accuracy

Tips & Best Practices

  • Ensure input values represent average speed over the hour for accurate conversion
  • Use high-precision instruments when measuring very slow velocities due to small conversion values
  • Avoid rounding errors by using full decimal precision during conversion calculations
  • Confirm consistent units to maintain clarity in engineering and scientific reports
  • Cross-check converted values when applying in critical industrial or geological monitoring

Limitations

  • Foot/hour unit applies only to very slow speeds; converted values in mm/s are very small
  • Small magnitude of conversion factor can introduce rounding errors
  • Assumes speed is constant throughout the hour, which may not reflect actual variations
  • Requires precise instrumentation to measure and verify converted speeds accurately

Frequently Asked Questions

What does one foot/hour represent?
One foot/hour (ft/h) is an imperial speed unit indicating travel of one foot over the span of an hour, typically used for very slow speeds.

Why convert foot/hour to millimeter/second?
Converting to millimeter/second enables expressing slow imperial speeds in metric terms suitable for precise scientific and engineering measurements.

Can I use this conversion for fast speeds?
No, foot/hour is intended for very slow velocities. Using it for faster speeds is not appropriate and may cause inaccurate or cumbersome results.

Key Terminology

Foot/hour (ft/h)
An imperial unit of speed representing one foot traveled in one hour, typically used for describing very slow velocities.
Millimeter/second (mm/s)
A metric speed unit describing one millimeter traveled each second, commonly used in precision engineering and low-speed motion control.
Conversion factor
The numeric value (0.0846666667) used to convert speed from foot/hour to millimeter/second.
