To convert liters per minute to barrels per day, multiply by 9.057327509. That factor is the whole relationship: both units measure volumetric flow, so the conversion is a proportion with no offset and no substance-specific constant.
The unit oil production is reported in worldwide. 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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in barrels per day, so you can sanity-check whether your answer is a plausible size.
The formula
liters per minute- The amount you are converting, in liters per minute
9.05732750942- The exact number of barrels per day in one liter per minute
barrels per day- The converted result
How it works, step by step
- Enter the value in liters per minute.
- It is multiplied by 9.05732750942, the exact factor between the two units.
- The answer is shown in barrels per day, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
The Thames at London: 3.9e+06 L/min in barrels per day
At 3.9e+06 L/min (the thames at london), the same quantity in barrels per day is 3.9e+06 × 9.05733 = 3.53236e+07 bbl/d. One liter per minute is 9.05733 barrels per day, so the numbers grow as expected.
A fire hydrant: 3600 L/min in barrels per day
Take a fire hydrant, roughly 3600 L/min. The conversion is a single multiplication — 3600 × 9.05733 — giving 32,606.4 bbl/d. Because the relationship is proportional, doubling the input doubles the answer to 65,212.8 bbl/d.

Frequently asked questions
How many barrels per day are in one liter per minute?
Exactly 9.05732750942. 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 barrels per day?
barrels per day = liters per minute × 9.05732750942. Reversed, liters per minute = barrels per day ÷ 9.05732750942, which is the same as multiplying by 0.1104078437.
Which is the bigger unit, the liter per minute or the barrel per day?
The liter per minute. One liter per minute equals 9.05733 barrels per day.
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 barrel per day?
The unit oil production is reported in worldwide.
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/min to bbl/d in my head?
Plenty of people do this in their head: multiply by 9 instead of using the exact factor 9.057327509. At 100 that shortcut gives 900 barrels per day, off by 5.733 barrels per day or about 0.63%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
