This page converts barrels per day into cubic meters per second using the factor 1.840130728e-06, and shows the reverse figure alongside it. Both units measure volumetric flow, which is why one number does the whole job.
The SI unit of volumetric flow, used for rivers and large ducts. 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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in cubic meters per second, so you can sanity-check whether your answer is a plausible size.
The formula
barrels per day- The amount you are converting, in barrels per day
1.84013072833e-06- The exact number of cubic meters per second in one barrel per day
cubic meters per second- The converted result
How it works, step by step
- Enter the value in barrels per day.
- It is multiplied by 1.84013072833e-06, the exact factor between the two units.
- The answer is shown in cubic meters 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 cubic meters per second
A shower head comes to about 87 bbl/d. Multiplying by the factor: 87 × 1.84013e-06 = 0.000160091 m³/s. Dividing the answer back by 1.84013e-06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A fire hydrant: 3.26e+04 bbl/d in cubic meters per second
Take a fire hydrant, roughly 3.26e+04 bbl/d. The conversion is a single multiplication — 3.26e+04 × 1.84013e-06 — giving 0.0599883 m³/s. Because the relationship is proportional, doubling the input doubles the answer to 0.119977 m³/s.

Frequently asked questions
How many cubic meters per second are in one barrel per day?
Exactly 1.84013072833e-06. 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 cubic meters per second?
cubic meters per second = barrels per day × 1.84013072833e-06. Reversed, barrels per day = cubic meters per second ÷ 1.84013072833e-06, which is the same as multiplying by 543,439.650565.
Which is the bigger unit, the barrel per day or the cubic meter per second?
The cubic meter per second. One barrel per day is only 1.84013e-06 of a cubic meter per second, so it takes 543,440 barrels per day to make one cubic meter 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 cubic meter per second?
The SI unit of volumetric flow, used for rivers and large ducts.
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 m³/s in my head?
Plenty of people do this in their head: divide by 540,000 instead of using the exact factor 0.000002. At 100 that shortcut gives 0.00018518519 cubic meters per second, off by 0.000001 cubic meters per second or about 0.64%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
