This converter allows you to convert radians per day [rad/d] to revolutions per second [1/s] or revolutions per second [1/s] to radians per day [rad/d]. 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 radian per day [rad/d] ≈ 1.842 * 10-6 revolutions per second [1/s]1 revolution per second [1/s] ≈ 542,867.2105 radians per day [rad/d]

Convert radians per day to revolutions per second

There are two simple ways to convert radians per day [rad/d] to revolutions per second [1/s]. In the first calculation method, the value in radians per day [rad/d] is divided by the rounded conversion factor of 542,867.2105. The second method multiplies the value in radians per day [rad/d] by the rounded conversion factor of 1.842 * 10-6.

  • Revolutions per second [1/s] ≈ radians per day [rad/d] ÷ 542,867.2105
  • Revolutions per second [1/s] ≈ radians per day [rad/d] * 1.842 * 10-6

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

  • Revolutions per second [1/s] = radians per day [rad/d] ÷ 172,800 ÷ π

Convert revolutions per second to radians per day

Converting revolutions per second [1/s] to radians per day [rad/d] is easy and can be done in two ways. The first method involves multiplication, in which the value in revolutions per second [1/s] is multiplied by the rounded conversion factor of 542,867.2105. The second variant is a division. Here, the value in revolutions per second [1/s] is divided by the rounded conversion factor of 1.842 * 10-6.

  • Radians per day [rad/d] ≈ revolutions per second [1/s] * 542,867.2105
  • Radians per day [rad/d] ≈ revolutions per second [1/s] ÷ (1.842 * 10-6)

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of revolutions per second [1/s] to radians per day [rad/d] can be achieved using the following calculation method.

  • Radians per day [rad/d] = revolutions per second [1/s] * 172,800 * π
