To convert barrels per day to liters per second, multiply by 0.001840130728. 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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into liters per second, which is usually more useful than the bare number.
The formula
barrels per day- The amount you are converting, in barrels per day
0.00184013072833- The exact number of liters per second in one barrel per day
liters per second- The converted result
How it works, step by step
- Enter the value in barrels per day.
- It is multiplied by 0.00184013072833, the exact factor between the two units.
- The answer is shown in liters per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A shower head: 87 bbl/d in liters per second
At 87 bbl/d (a shower head), the same quantity in liters per second is 87 × 0.00184013 = 0.160091 L/s. One barrel per day is 0.00184013 liters per second, so the numbers shrink as expected.
A fire hydrant: 3.26e+04 bbl/d in liters per second
A fire hydrant comes to about 3.26e+04 bbl/d. Multiplying by the factor: 3.26e+04 × 0.00184013 = 59.9883 L/s. Dividing the answer back by 0.00184013 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 liters per second are in one barrel per day?
Exactly 0.00184013072833. 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 barrels per day to liters per second?
liters per second = barrels per day × 0.00184013072833. Reversed, barrels per day = liters per second ÷ 0.00184013072833, which is the same as multiplying by 543.439650565.
Which is the bigger unit, the barrel per day or the liter per second?
The liter per second. One barrel per day is only 0.00184013 of a liter per second, so it takes 543.44 barrels per day to make one liter per second.
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 barrel per day?
The unit oil production is reported in worldwide.
What is a liter per second?
Used for plumbing design and compressed air.
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 bbl/d to L/s in my head?
Plenty of people do this in their head: divide by 540 instead of using the exact factor 0.001840130728. At 100 that shortcut gives 0.18518519 liters per second, off by 0.001172 liters per second or about 0.64%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
