cubic meters per hour to liters per minute

Plant-scale flow is quoted in cubic meters per hour; the pumps that deliver it are often sized in liters per minute. The bridge is 16.6666666667, the exact number of liters per minute in a cubic meter per hour — a 12 m³/h circulation pump moves 200 L/min, a 60 m³/h plant feed is 1,000 L/min, and both conversions are exact because the meter, the liter, and the minute are all definitions.

cubic meters per hour to liters per minute

One m³/h is 1,000 liters per 60 minutes = 16.6666666667 L/min. The repeating decimal is the only awkwardness — it is the reciprocal of the clean 0.06 factor that goes the other way, and it is exact even though it never terminates. Municipal water, HVAC circulation, and process plants all move between these two scales daily, and because the conversion is definitional, the 16.667 is a constant you can trust to every digit, not an approximation to be rounded early.

liters per minute = cubic meters per hour × 16.6666666667
1 m³/h = 16.6666666667 L/min — 1,000 L ÷ 60 min
The factor is exact: the reciprocal of 0.06.

Engineering Context

This is the reciprocal of the L/min to m³/h page. The 1,000 comes from the cubic meters to liters volume anchor and the 60 from the time family. The flow rate hub collects the full family, and HVAC circulation also touches the energy pages, since flow × temperature drop is how heating load is carried.

Frequently Asked Questions

How many L/min is 1 m³/h?

Exactly 16.6666666667. A cubic meter per hour is 1,000 liters divided by 60 minutes — an exact ratio of definitions, even though the decimal repeats.

Why does 1/0.06 never terminate?

Because 0.06 = 3/50 as a fraction, and 50/3 = 16.666... The repeating 6 is inherent to the factor's construction from 60 and 1,000 — it is exact, not approximate.

Can I use 16.67 as a shortcut?

Yes, for estimates — 16.67 is within 0.02% of the true value. For spec-level work use the full 16.6666666667, especially when the flow is large enough that rounding compounds.
