Convert millimeters per hour to feet per hour

There are two simple ways to convert millimeters per hour [mm/h] to feet per hour [ft/h]. In the first calculation method, the value in millimeters per hour [mm/h] is divided by 304.8. The second method multiplies the value in millimeters per hour [mm/h] by the rounded conversion factor of 0.0033.

  • Feet per hour [ft/h] = millimeters per hour [mm/h] ÷ 304.8
  • Feet per hour [ft/h] ≈ millimeters per hour [mm/h] * 0.0033

The calculation method with a rounded conversion value is more suitable for rough conversions from millimeters per hour [mm/h] to feet per hour [ft/h], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.
