This converter allows you to convert revolutions per hour [1/h] to radians per day [rad/d] or radians per day [rad/d] to revolutions per hour [1/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 revolution per hour [1/h] ≈ 150.7964 radians per day [rad/d]1 radian per day [rad/d] ≈ 0.0066 revolutions per hour [1/h]

Convert revolutions per hour to radians per day

There are two simple ways to convert revolutions per hour [1/h] to radians per day [rad/d]. In the first calculation method, the value in revolutions per hour [1/h] is divided by the rounded conversion factor of 0.0066. The second method multiplies the value in revolutions per hour [1/h] by the rounded conversion factor of 150.7964.

  • Radians per day [rad/d] ≈ revolutions per hour [1/h] ÷ 0.0066
  • Radians per day [rad/d] ≈ revolutions per hour [1/h] * 150.7964

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of revolutions per hour [1/h] to radians per day [rad/d] can be achieved using the following calculation method.

  • Radians per day [rad/d] = revolutions per hour [1/h] * 48 * π

Convert radians per day to revolutions per hour

Converting radians per day [rad/d] to revolutions per hour [1/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 0.0066. The second variant is a division. Here, the value in radians per day [rad/d] is divided by the rounded conversion factor of 150.7964.

  • Revolutions per hour [1/h] ≈ radians per day [rad/d] * 0.0066
  • Revolutions per hour [1/h] ≈ radians per day [rad/d] ÷ 150.7964

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 revolutions per hour [1/h] can be achieved using the following calculation method.

  • Revolutions per hour [1/h] = radians per day [rad/d] ÷ 48 ÷ π
