Use the Liters per second to Cubic meters per second Converter
Liters per second to Cubic meters per second formula and what each symbol means
m³/s = L/s × 0.001
| Symbol | Meaning |
|---|---|
| L/s | Liter per second |
| m³/s | Cubic meter per second |
Liters per second to Cubic meters per second examples
1 L/s
1 L/s × 0.001 = 0.001 m³/s.
10 L/s
10 L/s × 0.001 = 0.01 m³/s.
100 L/s
100 L/s × 0.001 = 0.1 m³/s.
Liters per second compared with Cubic meters per second
One m³/s is 1,000 times as large as one L/s, so your number gets smaller when you convert liters per second to cubic meters per second and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About liters per second and cubic meters per second
Liter per second (L/s): One thousandth of a cubic metre per second. Cubic meter per second (m³/s): The SI unit of volumetric flow rate.
How to calculate Liters per second to Cubic meters per second step by step
- Enter the value in L/s (the starting unit).
- Multiply by 0.001, because 1 L/s = 0.001 m³/s.
- The product is the value in m³/s. To go back, divide by 0.001 or multiply by 1,000.
