This converter allows you to convert revolutions per hour [1/h] to radians per second [rad/s] or radians per second [rad/s] 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] ≈ 0.0017 radians per second [rad/s]1 radian per second [rad/s] ≈ 572.9578 revolutions per hour [1/h]

Convert revolutions per hour to radians per second

There are two simple ways to convert revolutions per hour [1/h] to radians per second [rad/s]. In the first calculation method, the value in revolutions per hour [1/h] is divided by the rounded conversion factor of 572.9578. The second method multiplies the value in revolutions per hour [1/h] by the rounded conversion factor of 0.0017.

  • Radians per second [rad/s] ≈ revolutions per hour [1/h] ÷ 572.9578
  • Radians per second [rad/s] ≈ revolutions per hour [1/h] * 0.0017

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 second [rad/s] can be achieved using the following calculation method.

  • Radians per second [rad/s] = revolutions per hour [1/h] ÷ 1,800 * π

Convert radians per second to revolutions per hour

Converting radians per second [rad/s] 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 second [rad/s] is multiplied by the rounded conversion factor of 572.9578. The second variant is a division. Here, the value in radians per second [rad/s] is divided by the rounded conversion factor of 0.0017.

  • Revolutions per hour [1/h] ≈ radians per second [rad/s] * 572.9578
  • Revolutions per hour [1/h] ≈ radians per second [rad/s] ÷ 0.0017

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

  • Revolutions per hour [1/h] = radians per second [rad/s] * 1,800 ÷ π
