Convert miles per hour to knots

There are two simple ways to convert miles per hour [mi/h] to knots [kn]. In the first calculation method, the value in miles per hour [mi/h] is divided by the rounded conversion factor of 1.1508. The second method multiplies the value in miles per hour [mi/h] by the rounded conversion factor of 0.869.

  • Knots [kn] ≈ miles per hour [mi/h] ÷ 1.1508
  • Knots [kn] ≈ miles per hour [mi/h] * 0.869

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 knots [kn] can be achieved using the following calculation method.

  • Knots [kn] = miles per hour [mi/h] ÷ 1,852 * 1,609.344

Convert knots to miles per hour

Converting knots [kn] 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 knots [kn] is multiplied by the rounded conversion factor of 1.1508. The second variant is a division. Here, the value in knots [kn] is divided by the rounded conversion factor of 0.869.

  • Miles per hour [mi/h] ≈ knots [kn] * 1.1508
  • Miles per hour [mi/h] ≈ knots [kn] ÷ 0.869

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

  • Miles per hour [mi/h] = knots [kn] * 1,852 ÷ 1,609.344
