Frequently asked questions

Symbols and assumptions

mph
Input unit — mile per hour
ft/s
Output unit — foot per second
m/s
Base unit used internally for speed and velocity
  • Both units measure speed and velocity, so the physical quantity is unchanged by the conversion.
  • The relationship is exactly linear: 1 mph = 1.466666667 ft/s.
  • Values are converted through the SI base unit for this quantity rather than pair by pair.

  • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
  • Displayed figures are rounded for readability; the full stored precision of the ft/s value is used in every onward calculation.
