Convert Miles per Hour to Feet per Second

Converting Miles per Hour (mph) to Feet per Second (ft/s) is a common task in speed measurements. Speed conversions connect metric road limits, aviation knots, and imperial miles per hour — common when traveling internationally or reading foreign weather reports.

Formula: Multiply the miles per hour value by 1.46667. In equation form: ft/s = mph × 1.46667.

One miles per hour equals approximately 1.466667 ft/s. This means you can multiply any mph value by 1.466667 to get the equivalent in ft/s.

For instance, converting 1 mph gives 1.466667 ft/s. Try different values using the quick-value chips or type directly into the input field.

Common mistake: Knots measure nautical miles per hour, not statute miles — they are close but not identical to mph.
