Cubic meter per hour to Liter per minute Formula & Unit Definitions
The conversion formula derives directly from standard metric dimensional definitions: one cubic meter contains exactly 1,000 liters, and one hour contains 60 minutes. Dividing 1,000 liters by 60 minutes yields 16.66666667 L/min (or approximately 16.6667 L/min). Multiplying any flow rate in cubic meters per hour by 16.6667 (or multiplying by 50 and dividing by 3) provides the exact equivalent in liters per minute.
Quick Estimation: Quick mental shortcut: To convert m³/h to L/min in your head, multiply by 50 and divide by 3 (or multiply by 16.7). For example, 3 m³/h × 50 ÷ 3 = 50 L/min; 6 m³/h × 50 ÷ 3 = 100 L/min; 12 m³/h gives 200 L/min.
Cubic meter per hour — m³/h
SI Industrial Metric- Standard international metric unit for bulk volumetric flow handling (1 m³/h = 1,000 L/h)

- Directly equivalent to exactly 0.06 cubic meters per hour
Frequently Asked Questions
Q.What is the exact formula to convert cubic meters per hour to liters per minute?
Multiply the flow rate in cubic meters per hour by 16.6667 (or divide by 0.06). For example, 6 m³/h × 16.6667 = 100 L/min.
Q.What is the reverse conversion from liters per minute to cubic meters per hour?
To convert back, use the Liters per Minute to Cubic Meters per Hour Converter where you multiply L/min by 0.06.
Q.How many liters per minute are in 1 cubic meter per hour?
One cubic meter per hour equals exactly 16.666667 liters per minute, calculated as 1,000 liters divided by 60 minutes.
Q.What is 3 m³/h in liters per minute?
3 cubic meters per hour equals exactly 50 liters per minute (L/min), a typical flow rate for small residential circulation pumps.
