How many m³/h is 1 liter per minute?

1 liter per minute equals exactly 0.06 cubic meters per hour. The conversion is exact because 1 m³ = 1,000 L and 1 hour = 60 minutes, so 1 L/min = (1/1000) m³ / (1/60) h = 60/1000 m³/h = 0.06 m³/h.

How do I convert L/min to m³/h manually?

Multiply the L/min value by 0.06. For example, 50 L/min × 0.06 = 3 m³/h. Alternatively, divide L/min by 16.6667.

How do I convert m³/h back to L/min?

Divide the m³/h value by 0.06, or equivalently multiply by 16.6667. For example, 3 m³/h ÷ 0.06 = 50 L/min.

Is the 0.06 factor exact?

Yes. Since 1 m³ = exactly 1,000 liters and 1 hour = exactly 60 minutes, the factor 0.06 is a defined exact value with no rounding error.

What flow rates are typical for HVAC systems?

Small fan coil units handle roughly 0.5–2 m³/h (8–33 L/min). Central air handling units range from 5–50 m³/h (83–833 L/min). Large district cooling plants can exceed 500 m³/h (8,333 L/min).

Why do some systems use L/min and others m³/h?

L/min is common for smaller-scale instrumentation, laboratory equipment, and pump test benches. m³/h is preferred in process engineering, HVAC design, and water treatment where flows are larger and hourly totals matter.
