One barrel per day is exactly 6.624470622 liters per hour, so converting barrels per day to liters per hour 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 rating unit for dosing pumps, drip irrigation and small boilers. 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 hour, which is usually more useful than the bare number.
The formula
barrels per day- The amount you are converting, in barrels per day
6.624470622- The exact number of liters per hour in one barrel per day
liters per hour- The converted result
How it works, step by step
- Enter the value in barrels per day.
- It is multiplied by 6.624470622, the exact factor between the two units.
- The answer is shown in liters per hour, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A bathroom tap: 54.3 bbl/d in liters per hour
A bathroom tap comes to about 54.3 bbl/d. Multiplying by the factor: 54.3 × 6.62447 = 359.709 L/h. Dividing the answer back by 6.62447 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
A garden hose: 163 bbl/d in liters per hour
At 163 bbl/d (a garden hose), the same quantity in liters per hour is 163 × 6.62447 = 1079.79 L/h. One barrel per day is 6.62447 liters per hour, so the numbers grow as expected.

Frequently asked questions
How many liters per hour are in one barrel per day?
Exactly 6.624470622. 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 hour?
liters per hour = barrels per day × 6.624470622. Reversed, barrels per day = liters per hour ÷ 6.624470622, which is the same as multiplying by 0.15095545849.
Which is the bigger unit, the barrel per day or the liter per hour?
The barrel per day. One barrel per day equals 6.62447 liters per hour.
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 hour?
The rating unit for dosing pumps, drip irrigation and small boilers.
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/h in my head?
Plenty of people do this in their head: multiply by 6.6 instead of using the exact factor 6.624470622. At 100 that shortcut gives 660 liters per hour, off by 2.447 liters per hour or about 0.37%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
