One cubic meter per second is exactly 543,439.6506 barrels per day, so converting cubic meters per second to barrels per day 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 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. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into barrels per day, which is usually more useful than the bare number.
The formula
cubic meters per second- The amount you are converting, in cubic meters per second

Worked examples
The Thames at London: 65 m³/s in barrels per day
At 65 m³/s (the thames at london), the same quantity in barrels per day is 65 × 543,440 = 3.53236e+07 bbl/d. One cubic meter per second is 543,440 barrels per day, so the numbers grow as expected.
A shower head: 0.00016 m³/s in barrels per day
At 0.00016 m³/s (a shower head), the same quantity in barrels per day is 0.00016 × 543,440 = 86.9503 bbl/d. One cubic meter per second is 543,440 barrels per day, so the numbers grow as expected.

Frequently asked questions
How many barrels per day are in one cubic meter per second?
Exactly 543,439.650565. 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 cubic meters per second to barrels per day?
barrels per day = cubic meters per second × 543,439.650565. Reversed, cubic meters per second = barrels per day ÷ 543,439.650565, which is the same as multiplying by 1.84013072833e-06.
Which is the bigger unit, the cubic meter per second or the barrel per day?
The cubic meter per second. One cubic meter per second equals 543,440 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 cubic meter per second?
The SI unit of volumetric flow, used for rivers and large ducts.
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 m³/s to bbl/d in my head?
Plenty of people do this in their head: multiply by 540,000 instead of using the exact factor 543,439.6506. At 100 that shortcut gives 54,000,000 barrels per day, off by 343965.056533 barrels per day or about 0.63%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
