This converter allows you to convert degrees per hour [°/h] to radians per day [rad/d] or radians per day [rad/d] to degrees per hour [°/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 degree per hour [°/h] ≈ 0.4189 radians per day [rad/d]1 radian per day [rad/d] ≈ 2.3873 degrees per hour [°/h]

Convert degrees per hour to radians per day

There are two simple ways to convert degrees per hour [°/h] to radians per day [rad/d]. In the first calculation method, the value in degrees per hour [°/h] is divided by the rounded conversion factor of 2.3873. The second method multiplies the value in degrees per hour [°/h] by the rounded conversion factor of 0.4189.

  • Radians per day [rad/d] ≈ degrees per hour [°/h] ÷ 2.3873
  • Radians per day [rad/d] ≈ degrees per hour [°/h] * 0.4189

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of degrees per hour [°/h] to radians per day [rad/d] can be achieved using the following calculation method.

  • Radians per day [rad/d] = degrees per hour [°/h] ÷ 7.5 * π

Convert radians per day to degrees per hour

Converting radians per day [rad/d] to degrees per hour [°/h] is easy and can be done in two ways. The first method involves multiplication, in which the value in radians per day [rad/d] is multiplied by the rounded conversion factor of 2.3873. The second variant is a division. Here, the value in radians per day [rad/d] is divided by the rounded conversion factor of 0.4189.

  • Degrees per hour [°/h] ≈ radians per day [rad/d] * 2.3873
  • Degrees per hour [°/h] ≈ radians per day [rad/d] ÷ 0.4189

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of radians per day [rad/d] to degrees per hour [°/h] can be achieved using the following calculation method.

  • Degrees per hour [°/h] = radians per day [rad/d] * 7.5 ÷ π
