As we know One °/d is equal to 0.000001929 r/min (1 °/d = 0.000001929 r/min).

To convert Degree/day to Revolution/minute, multiply your °/d figure by 0.000001929.

Example : convert 25 °/d to r/min:

25 °/d = 25 × 0.000001929 r/min = r/min

To convert Revolution/minute to Degree/day, divide your r/min figure by 0.000001929.

Example : convert 25 r/min to °/d:

25 r/min = 25 ÷ 0.000001929 °/d = °/d
