To convert liters per second to barrels per day, multiply by 543.4396506. 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.
Used for plumbing design and compressed air. The unit oil production is reported in worldwide.
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 barrels per day so the number you get has something to be compared against.
The formula
liters per second- The amount you are converting, in liters per second
543.439650565- The exact number of barrels per day in one liter per second
barrels per day- The converted result
How it works, step by step
- Enter the value in liters per second.
- It is multiplied by 543.439650565, 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
A garden hose: 0.3 L/s in barrels per day
A garden hose comes to about 0.3 L/s. Multiplying by the factor: 0.3 × 543.44 = 163.032 bbl/d. Dividing the answer back by 543.44 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A bathroom tap: 0.1 L/s in barrels per day
At 0.1 L/s (a bathroom tap), the same quantity in barrels per day is 0.1 × 543.44 = 54.344 bbl/d. One liter per second is 543.44 barrels per day, so the numbers grow as expected.
How to read your score
Frequently asked questions
How many barrels per day are in one liter per second?
Exactly 543.439650565. 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 second to barrels per day?
barrels per day = liters per second × 543.439650565. Reversed, liters per second = barrels per day ÷ 543.439650565, which is the same as multiplying by 0.00184013072833.
Which is the bigger unit, the liter per second or the barrel per day?
The liter per second. One liter per second equals 543.44 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 second?
Used for plumbing design and compressed air.
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/s to bbl/d in my head?
Plenty of people do this in their head: multiply by 540 instead of using the exact factor 543.4396506. At 100 that shortcut gives 54,000 barrels per day, off by 344 barrels per day or about 0.63%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
