Liters per second to Cubic meters per hour formula and what each symbol means
m³/h = L/s × 3.6
| Symbol | Meaning |
|---|---|
| L/s | Liter per second |
| m³/h | Cubic meter per hour |
Liters per second to Cubic meters per hour examples
1 L/s
1 L/s × 3.6 = 3.6 m³/h.
10 L/s
10 L/s × 3.6 = 36 m³/h.
100 L/s
100 L/s × 3.6 = 360 m³/h.
Liters per second compared with Cubic meters per hour
One L/s is 3.6 times as large as one m³/h, so your number gets bigger when you convert liters per second to cubic meters per hour and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About liters per second and cubic meters per hour
Liter per second (L/s): One thousandth of a cubic metre per second. Cubic meter per hour (m³/h): Cubic metres per hour, about 2.778×10⁻⁴ m³/s.
