Calculate liters per second from cubic meters per hour: convert flow between m3/h, L/s, CFM, GPM, L/min and m3/s, plus duct velocity and air changes per hour.
m3/h to l/s Formula
The following formula is used to convert m3/h to l/s.
- Where l/s is the liters per second
- m3/h is the cubic meters per hour
To calculate l/s from m3/h, divide the mยณ/h by 3.6 exactly (multiplication by 0.27778 is an approximation).
| Flow (mยณ/h) | Flow (L/s) |
|---|---|
| 0.1 | 0.028 |
| 0.25 | 0.069 |
| 0.5 | 0.139 |
| 1 | 0.278 |
| 1.5 | 0.417 |
| 2 | 0.556 |
| 2.5 | 0.694 |
| 3 | 0.833 |
| 4 | 1.111 |

| Conversion factors: 1 mยณ/h โ 0.277778 L/s (exactly รท 3.6). Conversely, 1 L/s = 3.6 mยณ/h. | |
How do you convert m3/h to l/s? In order to convert to liters per second, divide the flow in mยณ/h by 3.6. The result is L/s; 0.27778 is a rounded multiplier.
How do you convert l/s to m3/h? To convert the l/s into m3/h, multiply the flow in L/s by 3.6 exactly.
Example Problem
How to calculate l/s from m3/h?
First, determine the total flow in cubic meters per hour.
For this example, the total m3/h is found to be 18.
Next, use the formula for the conversion above to determine the amount of l/s.
L/s = (mยณ/h) / 3.6
L/s = 18 / 3.6 = 5
l/s = 5
