Conversion chart
1 megahertz equals 1,000,000 hertz.
Hertz (Hz) One hertz equals 1 hertz.
The hertz is named for Heinrich Hertz and was adopted for cycles per second.
1. Parse the value, including fractions.
2. Convert Hz to hertz.
3. Convert the base value to rpm and apply your display precision.
Understand the result before using it
Hertz to Revolutions per minute converts a value measured in Hertz (Hz) into the equivalent value in Revolutions per minute (rpm). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
result = input × 1 ÷ 0.016666666666666666
Assumptions
- Hertz and Revolutions per minute represent the same frequency quantity.
- The input is expressed in Hz; the output is expressed in rpm.
- The unit definitions and conventional relationship shown on this page apply.
1 Hz = 60 rpm. For another value, apply the same relationship and round only to the precision your source measurement supports.
Good uses
- Read a Hz measurement in a document that expects rpm.
- Compare a hertz value with a value reported in revolutions per minute.
- Check the Hz-to-rpm arithmetic before copying the result into another calculation.
Common mistakes to avoid
- Do not confuse Hz with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.
