One liter per minute is exactly 1000 milliliters per minute, so converting liters per minute to milliliters per minute is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min. The flow unit for taps, showers and medical oxygen.
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. Below the calculator there is a step table for the values people look up most, and a second table putting real volumetric flow figures into milliliters per minute so the number you get has something to be compared against.
The formula
liters per minute- The amount you are converting, in liters per minute
1000- The exact number of milliliters per minute in one liter per minute
milliliters per minute- The converted result
How it works, step by step
- Enter the value in liters per minute.
- It is multiplied by 1000, the exact factor between the two units.
- The answer is shown in milliliters 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 milliliters per minute
At 0.006 L/min (a dripping tap), the same quantity in milliliters per minute is 0.006 × 1000 = 6 mL/min. One liter per minute is 1000 milliliters per minute, so the numbers grow as expected.
A garden hose: 18 L/min in milliliters per minute
At 18 L/min (a garden hose), the same quantity in milliliters per minute is 18 × 1000 = 18,000 mL/min. One liter per minute is 1000 milliliters per minute, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many milliliters per minute are in one liter per minute?
Exactly 1000. 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 milliliters per minute?
milliliters per minute = liters per minute × 1000. Reversed, liters per minute = milliliters per minute ÷ 1000, which is the same as multiplying by 0.001.
Which is the bigger unit, the liter per minute or the milliliter per minute?
The liter per minute. One liter per minute equals 1000 milliliters 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 milliliter per minute?
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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.
