This converter allows you to convert millimeters per second [mm/s] to feet per hour [ft/h] or feet per hour [ft/h] to millimeters per second [mm/s]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 millimeter per second [mm/s] ≈ 11.811 feet per hour [ft/h]1 foot per hour [ft/h] ≈ 0.0847 millimeters per second [mm/s]

Convert millimeters per second to feet per hour

There are two simple ways to convert millimeters per second [mm/s] to feet per hour [ft/h]. In the first calculation method, the value in millimeters per second [mm/s] is divided by the rounded conversion factor of 0.0847. The second method multiplies the value in millimeters per second [mm/s] by the rounded conversion factor of 11.811.

  • Feet per hour [ft/h] ≈ millimeters per second [mm/s] ÷ 0.0847
  • Feet per hour [ft/h] ≈ millimeters per second [mm/s] * 11.811

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of millimeters per second [mm/s] to feet per hour [ft/h] can be achieved using the following calculation method.

  • Feet per hour [ft/h] = millimeters per second [mm/s] ÷ 3.048 * 36

Convert feet per hour to millimeters per second

Converting feet per hour [ft/h] to millimeters per second [mm/s] is easy and can be done in two ways. The first method involves multiplication, in which the value in feet per hour [ft/h] is multiplied by the rounded conversion factor of 0.0847. The second variant is a division. Here, the value in feet per hour [ft/h] is divided by the rounded conversion factor of 11.811.

  • Millimeters per second [mm/s] ≈ feet per hour [ft/h] * 0.0847
  • Millimeters per second [mm/s] ≈ feet per hour [ft/h] ÷ 11.811

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 hour [ft/h] to millimeters per second [mm/s] can be achieved using the following calculation method.

  • Millimeters per second [mm/s] = feet per hour [ft/h] * 3.048 ÷ 36
