Convert Inverse minutes (ISO) to Revolutions per second

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

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

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