This page converts liters per minute into cubic meters per minute using the factor 0.001, and shows the reverse figure alongside it. Both units measure volumetric flow, which is why one number does the whole job.
The flow unit for taps, showers and medical oxygen. Compressor and large-fan output in metric markets.
Standard versus actual volume. Gas flow in CFM depends on pressure and temperature, which is why compressor ratings say SCFM and specify the reference conditions. Converting the number is exact; comparing two ratings measured at different conditions is not. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into cubic meters per minute, which is usually more useful than the bare number.
The formula
liters per minute- The amount you are converting, in liters per minute
0.001- The exact number of cubic meters per minute in one liter per minute
cubic meters per minute- The converted result
How it works, step by step
- Enter the value in liters per minute.
- It is multiplied by 0.001, the exact factor between the two units.
- The answer is shown in cubic meters per minute, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A dripping tap: 0.006 L/min in cubic meters per minute
A dripping tap comes to about 0.006 L/min. Multiplying by the factor: 0.006 × 0.001 = 6e-06 m³/min. Dividing the answer back by 0.001 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A bathroom tap: 6 L/min in cubic meters per minute
A bathroom tap comes to about 6 L/min. Multiplying by the factor: 6 × 0.001 = 0.006 m³/min. Dividing the answer back by 0.001 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many cubic meters per minute are in one liter per minute?
Exactly 0.001. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert liters per minute to cubic meters per minute?
cubic meters per minute = liters per minute × 0.001. Reversed, liters per minute = cubic meters per minute ÷ 0.001, which is the same as multiplying by 1000.
Which is the bigger unit, the liter per minute or the cubic meter per minute?
The cubic meter per minute. One liter per minute is only 0.001 of a cubic meter per minute, so it takes 1000 liters per minute to make one cubic meter per minute.
What does this quantity actually measure?
Both units measure volumetric flow. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a liter per minute?
The flow unit for taps, showers and medical oxygen.
What is a cubic meter per minute?
Compressor and large-fan output in metric markets.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
