This converter allows you to convert millimeters per hour [mm/h] to nautical miles per second [NM/s] or nautical miles per second [NM/s] 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] ≈ 1.5 * 10-10 nautical miles per second [NM/s]1 nautical mile per second [NM/s] ≈ 6.667 * 109 millimeters per hour [mm/h]

Convert millimeters per hour to nautical miles per second

There are two simple ways to convert millimeters per hour [mm/h] to nautical miles per second [NM/s]. In the first calculation method, the value in millimeters per hour [mm/h] is divided by the rounded conversion factor of 6.667 * 109. The second method multiplies the value in millimeters per hour [mm/h] by the rounded conversion factor of 1.5 * 10-10.

  • Nautical miles per second [NM/s] ≈ millimeters per hour [mm/h] ÷ (6.667 * 109)
  • Nautical miles per second [NM/s] ≈ millimeters per hour [mm/h] * 1.5 * 10-10

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 hour [mm/h] to nautical miles per second [NM/s] can be achieved using the following calculation method.

  • Nautical miles per second [NM/s] = millimeters per hour [mm/h] ÷ 66,672 ÷ 105

Convert nautical miles per second to millimeters per hour

Converting nautical miles per second [NM/s] to millimeters per hour [mm/h] is easy and can be done in two ways. The first method involves multiplication, in which the value in nautical miles per second [NM/s] is multiplied by the rounded conversion factor of 6.667 * 109. The second variant is a division. Here, the value in nautical miles per second [NM/s] is divided by the rounded conversion factor of 1.5 * 10-10.

  • Millimeters per hour [mm/h] ≈ nautical miles per second [NM/s] * 6.667 * 109
  • Millimeters per hour [mm/h] ≈ nautical miles per second [NM/s] ÷ (1.5 * 10-10)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of nautical miles per second [NM/s] to millimeters per hour [mm/h] can be achieved using the following calculation method.

  • Millimeters per hour [mm/h] = nautical miles per second [NM/s] * 66,672 * 105
