What to enter
| Input | Meaning and units |
|---|---|
| Value | Enter value using the definition in the method and example. |
| From | Select the unit or currency in which the entered number is currently expressed. |
| To | Select the unit or currency you need for the answer. |
Understanding your result
The converted value describes the same flow rate quantity in the selected target unit. Display rounding does not add precision to the original measurement.
Common mistakes
- Confusing the source and target units, or overlooking a prefix or case-sensitive symbol.
Check your calculation
- Convert to the target unit and then reverse the direction. Within display rounding, you should recover the original value.

How do I express this flow rate in another unit?
Enter the known flow rate value and choose its source and target units. The converter expresses the same quantity in the selected target unit.
Common uses
- Compare liquid or gas volume-flow rates.
- Translate a pump or pipe-flow specification into another unit.
How it works
For the displayed direction, 1 m³/s equals 3600 m³/h. The engine converts through the shared flow rate base quantity. US and imperial gallons differ. Barrels are US petroleum barrels of 42 US liquid gallons. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits.
Worked example
10 m³/s converts to 36000 m³/h. For the reverse direction, swap the units and enter 36000 m³/h; the result is approximately 10 m³/s.
