liters per minute to cubic meters per hour
L/min and m³/h are the two workhorse flow units of process engineering — L/min for equipment ratings, m³/h for municipal and industrial scale. The factor 0.06 is exact by construction: 1 L/min = 0.001 m³/min × 60 min/h = 0.06 m³/h. The reverse is 16.6666666667, the repeating decimal that comes from dividing by 0.06. Because the forward direction is a clean decimal, engineers use it as a mental rule: divide L/min by 16.667, or just remember the 0.06 multiplier.
cubic meters per hour = liters per minute × 0.06
1 L/min = 0.06 m³/h — 1,000 L per m³ and 60 min per hour
The factor is exact by definition.
Worked Examples
Example 1: Convert a 50 L/min dosing line
50 × 0.06 = 3 m³/h
Example 2: Convert a 250 L/min circulation pump
250 × 0.06 = 15 m³/h
Example 3: Convert a 1,500 L/min plant feed
1,500 × 0.06 = 90 m³/h

| 1,000 L/min | 60 m³/h | A municipal supply pump. |
| 10,000 L/min | 600 m³/h | A water treatment plant feed. |
Engineering Context
This page is pure decimal arithmetic between two metric units — the liters to cubic meters volume anchor supplies the 1,000, and the time family supplies the 60. The m³/h to L/min page runs it backward, and the flow rate hub collects all ten converters. For the pump curve's other axis, the pressure hub carries the head conversions.
This is the conversion that reconciles what a device displays with what the utility charges for. Water meters totalize in cubic meters, and a meter reading over a shift of eight hours is compared against a flow log recorded in liters per minute, so the 1,000 and the 60 have to be applied in the right order. The same pairing appears in reverse when a plant is asked to justify its consumption: the instantaneous instrument value has to be averaged and scaled into m³/h before it can be lined up with the bill. Getting the direction wrong here changes the answer by a factor of about 7,200, which is large enough to be noticed, and getting the rounding wrong only affects the last digit.

Frequently Asked Questions
How many m³/h is 1 L/min?
Exactly 0.06. One liter is 0.001 m³ and one hour has 60 minutes, so 1 L/min = 0.001 × 60 = 0.06 m³/h. This is exact by definition, not a measured constant.
Why is the reverse factor 16.667 a repeating decimal?
Because it is 1/0.06 = 16.6666666667, and 0.06 = 6/100 = 3/50, whose reciprocal is 50/3 = 16.666... The repeating 6s are the decimal signature of a factor built from 60 and 1,000.
Which unit should I use for a pump spec?
Use the unit of your audience: L/min for equipment-level process specs, m³/h for municipal and plant-scale work. The conversion is exact either way, so the choice is about readability, not accuracy.
