Convert Inverse minutes (ISO) to Revolutions per minute

Inverse minutes (ISO) → Revolutions per minute
min⁻¹ × 1 = rpm rpm × 1 = min⁻¹

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

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

min⁻¹ to rpm table
Inverse minutes (ISO) (min⁻¹) Revolutions per minute (rpm)
0.1 min⁻¹ 0.1 rpm
0.5 min⁻¹ 0.5 rpm
1 min⁻¹ 1 rpm
2 min⁻¹ 2 rpm
5 min⁻¹ 5 rpm
10 min⁻¹ 10 rpm
20 min⁻¹ 20 rpm
50 min⁻¹ 50 rpm
100 min⁻¹ 100 rpm
500 min⁻¹ 500 rpm
1000 min⁻¹ 1000 rpm
