Flow (Volumetric) formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in m³/s.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (m³/s) |
Flow (Volumetric) examples
m³/s to L/s
10 m³/s = 10,000 L/s.
m³/s to L/min
10 m³/s = 600,000 L/min.
m³/s to m³/h
10 m³/s = 36,000 m³/h.
How to calculate Flow (Volumetric) step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Flow (Volumetric) result
Volumetric flow is volume per unit time. The SI unit is cubic metre per second. As rough anchors, 1 US gallon per minute is about 3.785 L/min, and 1 cubic foot per minute is about 0.4719 L/s or 1.699 m³/h.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 M³/S |
|---|---|---|---|
| Cubic meter per second | m³/s | 1 m³/s = 1 m³/s | 1 m³/s |

Common mistakes when calculating Flow (Volumetric)
- Mixing US gallons with imperial gallons: the imperial gallon is about 20% bigger.
- Confusing L/min with L/s, which differ by a factor of 60.
- Mixing CFM (cubic feet per minute) with m³/h without converting.
Flow (Volumetric) FAQ
How many L/min is 1 gpm?
1 US gallon per minute is about 3.785 L/min.
How many m³/h is 1 CFM?
About 1.699 m³/h.
How do I convert L/s to m³/h?
Multiply litres per second by 3.6 to get cubic metres per hour.
What is the base unit for flow (volumetric)?
This converter uses cubic meter per second (m³/s) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two flow (volumetric) units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many liters per second are in 1 cubic meter per second?
1 m³/s = 1,000 L/s.
How many liters per minute are in 1 cubic meter per second?
1 m³/s = 60,000 L/min.
How many cubic meters per hour are in 1 cubic meter per second?
1 m³/s = 3,600 m³/h.
Which flow (volumetric) units does this converter support?
It covers 12 units: cubic meter per second (m³/s), liter per second (L/s), liter per minute (L/min), liter per hour (L/h), cubic meter per hour (m³/h), milliliter per minute (mL/min), US gallon per minute (gpm), US gallon per hour (gal/h), cubic foot per second (ft³/s), cubic foot per minute (CFM), imperial gallon per minute (imp gpm), barrel per day (bbl/d).
How accurate is the flow (volumetric) converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
