To convert rpm to revolutions per hour, multiply by 60.
The calculation uses 1 rpm = 60 rph. Results are displayed to at most 10 significant digits. Definitions can be exact while a displayed decimal is rounded. Match the displayed precision to your original measurement.
The formula
value in rph = value in rpm × 60
rpm- Input unit: rpm
rph- Output unit: revolutions per hour
How to use this calculator
- Enter a value in rpm.
- Multiply by the stored conversion factor.
- Read the result in rph; divide by the same factor to convert back.
Worked examples
Worked conversion
1 rpm × 60 ≈ 60 rph.
Reverse conversion
60 rph ÷ 60 ≈ 1 rpm. Rounding intermediate values can change the last displayed digit.
Frequently asked questions
What factor does this converter use?
It uses 60 rph per rpm.
Why can another converter show a slightly different answer?
Check the unit convention first (such as US versus Imperial or decimal versus binary), then compare rounding. Measurement uncertainty is separate from the unit conversion.
