One barrel per day is exactly 0.02428633039 imperial gallons per minute, so converting barrels per day to imperial gallons per minute 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 British pump unit, about 20% more volume per minute than the US gallon version. 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 imperial gallons per minute so the number you get has something to be compared against.
The formula
barrels per day- The amount you are converting, in barrels per day
0.024286330385- The exact number of imperial gallons per minute in one barrel per day
imperial gallons per minute- The converted result
How it works, step by step
- Enter the value in barrels per day.
- It is multiplied by 0.024286330385, the exact factor between the two units.
- The answer is shown in imperial gallons per minute, with the reverse conversion beneath it.

Worked examples
A dripping tap: 0.0543 bbl/d in imperial gallons per minute
Take a dripping tap, roughly 0.0543 bbl/d. The conversion is a single multiplication — 0.0543 × 0.0242863 — giving 0.00131875 gpm. Because the relationship is proportional, doubling the input doubles the answer to 0.0026375 gpm.
A garden hose: 163 bbl/d in imperial gallons per minute
At 163 bbl/d (a garden hose), the same quantity in imperial gallons per minute is 163 × 0.0242863 = 3.95867 gpm. One barrel per day is 0.0242863 imperial gallons per minute, so the numbers shrink as expected.

Frequently asked questions
How many imperial gallons per minute are in one barrel per day?
Exactly 0.024286330385. 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 imperial gallons per minute?
imperial gallons per minute = barrels per day × 0.024286330385. Reversed, barrels per day = imperial gallons per minute ÷ 0.024286330385, which is the same as multiplying by 41.1754260173.
Which is the bigger unit, the barrel per day or the imperial gallon per minute?
The imperial gallon per minute. One barrel per day is only 0.0242863 of a imperial gallon per minute, so it takes 41.1754 barrels per day to make one imperial gallon per minute.
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 imperial gallon per minute?
The British pump unit, about 20% more volume per minute than the US gallon version.
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 gpm in my head?
Plenty of people do this in their head: divide by 40 instead of using the exact factor 0.02428633039. At 100 that shortcut gives 2.5 imperial gallons per minute, off by 0.07137 imperial gallons per minute or about 2.94%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
