Frequently asked questions

How many liters/second are in one cubic meter/hour?

One cubic meter/hour is 0.277777778 L/s, so 100 m³/h is 27.7777778 L/s.

What is the formula to convert cubic meters/hour to liters/second?

L/s = m³/h × 0.277777778. Multiply the value in cubic meters/hour by 0.277777778 to get liters/second.

How do I convert liters/second back to cubic meters/hour?

m³/h = L/s × 3.6, so 1 L/s is 3.6 m³/h. The L/s to m³/h page carries the same table in that direction.
