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

Convert hertz to radians per day

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

  • Radians per day [rad/d] ≈ hertz [Hz] ÷ (1.842 * 10-6)
  • Radians per day [rad/d] ≈ hertz [Hz] * 542,867.2105

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

  • Radians per day [rad/d] = hertz [Hz] * 172,800 * π

Convert radians per day to hertz

Converting radians per day [rad/d] to hertz [Hz] 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 1.842 * 10-6. The second variant is a division. Here, the value in radians per day [rad/d] is divided by the rounded conversion factor of 542,867.2105.

  • Hertz [Hz] ≈ radians per day [rad/d] * 1.842 * 10-6
  • Hertz [Hz] ≈ radians per day [rad/d] ÷ 542,867.2105

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 hertz [Hz] can be achieved using the following calculation method.

  • Hertz [Hz] = radians per day [rad/d] ÷ 172,800 ÷ π
