Convert Revolutions per second to Inverse minutes (ISO)

Revolutions per second → Inverse minutes (ISO)
rps × 60 = min⁻¹ min⁻¹ × 0.01666667 = rps

To convert revolutions per second (rps) to inverse minutes (iso) (min⁻¹), multiply the revolutions per second value by 60. 1 rps = 60 min⁻¹, and 1 min⁻¹ = 0.01666667 rps. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert min⁻¹ to rps.
