Revolutions per Minute to Hertz Converter
1 revolution per minute ≈ 0.0166666667 hertz
1 revolution per minute equals 0.0166667 hertz
How to convert revolutions per minute to hertz
Hertz counts complete cycles per second. This converter treats one revolution as one cycle, so 60 rpm = 1 Hz; angular frequency in radians per second would additionally involve 2π.
Hz = rpm × 0.01666666667One revolution per minute is 0.01666666667 hertz, so a single multiplication converts any value.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
