How to convert degrees per second to revolutions per minute
Angular speed measures rotation, not linear speed. To find tangential speed you also need the radius. Revolutions per minute are divided by 60 when converted to revolutions per second.
Use x for the value in °/s, b for the intermediate value in rad/s, and y for the result in rpm.
rpm = °/s × 0.017453292519943295 ÷ 0.10471975511965977
Worked examples
10 °/s ≈ 1.66666666667 rpm
Step 1: (10 × 0.0174532925199) ≈ 0.174532925199 rad/s.
Step 2: 0.174532925199 ÷ 0.10471975512 ≈ 1.66666666667 rpm.20 °/s ≈ 3.33333333333 rpm
Step 1: (20 × 0.0174532925199) ≈ 0.349065850399 rad/s.
Step 2: 0.349065850399 ÷ 0.10471975512 ≈ 3.33333333333 rpm.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Degrees per second
Degrees per second (°/s) measures velocity angular under the conventions above. The base value in rad/s is (x × 0.0174532925199), where x is the numerical value in °/s. Factors shown here are rounded for display; calculations use the stored factor.
About Revolutions per minute
Revolutions per minute (rpm) measures velocity angular under the conventions above. The base value in rad/s is (x × 0.10471975512), where x is the numerical value in rpm. Factors shown here are rounded for display; calculations use the stored factor.
