ENGINEERING PRINCIPLE

Angular velocity expresses rotational speed in radians per second.

Calculate angular velocity from rotational speed.

FORMULA & VARIABLES

ω = 2πN / 60

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

CALCULATION STEPS

How this result is assembled

  1. Convert the entered values to the SI basis required by the formula.
  2. Apply ω = 2πN / 60 using the current inputs.
  3. Present the result as 150.796 rad/s 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.
