This converter allows you to convert miles per hour [mi/h] to feet per second [ft/s] or feet per second [ft/s] to miles per hour [mi/h]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert miles per hour to feet per second
There are two simple ways to convert miles per hour [mi/h] to feet per second [ft/s]. In the first calculation method, the value in miles per hour [mi/h] is divided by the rounded conversion factor of 0.6818. The second method multiplies the value in miles per hour [mi/h] by the rounded conversion factor of 1.4667.
- Feet per second [ft/s] ≈ miles per hour [mi/h] ÷ 0.6818
- Feet per second [ft/s] ≈ miles per hour [mi/h] * 1.4667
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of miles per hour [mi/h] to feet per second [ft/s] can be achieved using the following calculation method.
- Feet per second [ft/s] = miles per hour [mi/h] * 44.704 ÷ 30.48
Convert feet per second to miles per hour
Converting feet per second [ft/s] to miles per hour [mi/h] is easy and can be done in two ways. The first method involves multiplication, in which the value in feet per second [ft/s] is multiplied by the rounded conversion factor of 0.6818. The second variant is a division. Here, the value in feet per second [ft/s] is divided by the rounded conversion factor of 1.4667.
- Miles per hour [mi/h] ≈ feet per second [ft/s] * 0.6818
- Miles per hour [mi/h] ≈ feet per second [ft/s] ÷ 1.4667
However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of feet per second [ft/s] to miles per hour [mi/h] can be achieved using the following calculation method.
- Miles per hour [mi/h] = feet per second [ft/s] ÷ 44.704 * 30.48
