ENGINEERING PRINCIPLE

One revolution equals 2π radians, connecting angular velocity to revolutions per minute.

Calculate rotational speed in RPM from angular velocity.

FORMULA & VARIABLES

N = ω × 60 / (2π)

  • N = rotational speed (RPM)
  • ω = angular velocity (rad/s)

CALCULATION STEPS

How this result is assembled

  1. Convert the entered values to the SI basis required by the formula.
  2. Apply N = ω × 60 / (2π) using the current inputs.
  3. Present the result as 1,432.394 RPM and review the stated assumptions.

FORMULA VERIFICATION

Units, scope and reference

Reference: NIST SP 811 for unit relationships; standard classical mechanics and strength-of-materials derivations for the stated scalar relation.

Internal basis: All inputs are converted to the calculator’s SI base before the formula is evaluated.

Valid conditions: Positive finite scalar input values in the current calculator model.

Limitations: Steady rotational speed is assumed.

ASSUMPTIONS

Use this result in context

  • Steady rotational speed is assumed.

Results must be verified by a qualified engineer and checked against applicable engineering standards, material properties, loading conditions and design requirements.
