One liter per hour is exactly 16.66666667 milliliters per minute, so converting liters per hour 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.
The rating unit for dosing pumps, drip irrigation and small boilers. Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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 milliliters per minute, which is usually more useful than the bare number.
The formula
liters per hour- The amount you are converting, in liters per hour
16.6666666667- The exact number of milliliters per minute in one liter per hour
milliliters per minute- The converted result
How it works, step by step
- Enter the value in liters per hour.
- It is multiplied by 16.6666666667, 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 garden hose: 1080 L/h in milliliters per minute
At 1080 L/h (a garden hose), the same quantity in milliliters per minute is 1080 × 16.6667 = 18,000 mL/min. One liter per hour is 16.6667 milliliters per minute, so the numbers grow as expected.
A bathroom tap: 360 L/h in milliliters per minute
A bathroom tap comes to about 360 L/h. Multiplying by the factor: 360 × 16.6667 = 6000 mL/min. Dividing the answer back by 16.6667 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
How to read your score
Frequently asked questions
How many milliliters per minute are in one liter per hour?
Exactly 16.6666666667. 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 hour to milliliters per minute?
milliliters per minute = liters per hour × 16.6666666667. Reversed, liters per hour = milliliters per minute ÷ 16.6666666667, which is the same as multiplying by 0.06.
Which is the bigger unit, the liter per hour or the milliliter per minute?
The liter per hour. One liter per hour equals 16.6667 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 hour?
The rating unit for dosing pumps, drip irrigation and small boilers.
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.
Is there a quick way to do L/h to mL/min in my head?
Plenty of people do this in their head: multiply by 17 instead of using the exact factor 16.66666667. At 100 that shortcut gives 1700 milliliters per minute, off by 33.33 milliliters per minute or about 2.00%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
