This converter allows you to convert millimeters per hour [mm/h] to knots [kn] or knots [kn] to millimeters per hour [mm/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.

1 millimeter per hour [mm/h] ≈ 5.4 * 10-7 knots [kn]1 knot [kn] = 1,852,000 millimeters per hour [mm/h]

Convert millimeters per hour to knots

There are two simple ways to convert millimeters per hour [mm/h] to knots [kn]. In the first calculation method, the value in millimeters per hour [mm/h] is divided by 1,852,000. The second method multiplies the value in millimeters per hour [mm/h] by the rounded conversion factor of 5.4 * 10-7.

  • Knots [kn] = millimeters per hour [mm/h] ÷ 1,852,000
  • Knots [kn] ≈ millimeters per hour [mm/h] * 5.4 * 10-7

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


Convert knots to millimeters per hour

Converting knots [kn] to millimeters per hour [mm/h] is easy and can be done in two ways. The first method involves multiplication, whereby the value in knots [kn] is multiplied by 1,852,000. The second variant is a division. Here, the value in knots [kn] is divided by the rounded conversion factor of 5.4 * 10-7.

  • Millimeters per hour [mm/h] = knots [kn] * 1,852,000
  • Millimeters per hour [mm/h] ≈ knots [kn] ÷ (5.4 * 10-7)

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from knots [kn] to millimeters per hour [mm/h] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
