How to convert liters per second to cubic meters per hour

Multiply the number of liters per second by 3.6 to get cubic meters per hour: m³/h = L/s × 3.6.

Example: 5 L/s = 18 m³/h.

The liter per second (L/s) and the cubic meter per hour (m³/h) are both units of flow rate. Need the opposite direction? Use the m³/h to L/s converter.

Metric and imperial units

The metric system (SI) is used by almost every country and by science worldwide. Its units scale by powers of ten – 1 kilometer is 1,000 meters, 1 meter is 100 centimeters – which makes conversions inside the system easy. The imperial and US customary systems (inches, feet, pounds, gallons) are still used daily in the United States and partly in the UK.

Since 1959 the inch has been defined as exactly 2.54 centimeters and the pound as exactly 0.45359237 kilograms, so conversions between the two systems are exact. Note that a US gallon (3.785 L) and an imperial gallon (4.546 L) are different – choose the right one above.

This converter covers 18 categories and 106 units: length, weight, temperature, volume, area, speed, time, data, energy, pressure, power, angle, force, torque, frequency, flow rate, illuminance, density.
