To convert liters per minute to acre-feet per day, multiply by 0.001167426999. 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.
The flow unit for taps, showers and medical oxygen. Irrigation and reservoir release rates in the western United States.
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 acre-feet per day, which is usually more useful than the bare number.
The formula
liters per minute- The amount you are converting, in liters per minute
0.0011674269991- The exact number of acre-feet per day in one liter per minute
acre-feet per day- The converted result
How it works, step by step
- Enter the value in liters per minute.
- It is multiplied by 0.0011674269991, the exact factor between the two units.
- The answer is shown in acre-feet per day, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
The Thames at London: 3.9e+06 L/min in acre-feet per day
Take the thames at london, roughly 3.9e+06 L/min. The conversion is a single multiplication — 3.9e+06 × 0.00116743 — giving 4552.97 ac ft/d. Because the relationship is proportional, doubling the input doubles the answer to 9105.93 ac ft/d.
A bathroom tap: 6 L/min in acre-feet per day
A bathroom tap comes to about 6 L/min. Multiplying by the factor: 6 × 0.00116743 = 0.00700456 ac ft/d. Dividing the answer back by 0.00116743 returns the figure you started with, which is the quickest way to check you have the factor the right way up.

Frequently asked questions
How many acre-feet per day are in one liter per minute?
Exactly 0.0011674269991. 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 liters per minute to acre-feet per day?
acre-feet per day = liters per minute × 0.0011674269991. Reversed, liters per minute = acre-feet per day ÷ 0.0011674269991, which is the same as multiplying by 856.58460938.
Which is the bigger unit, the liter per minute or the acre-foot per day?
The acre-foot per day. One liter per minute is only 0.00116743 of a acre-foot per day, so it takes 856.585 liters per minute to make one acre-foot 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 liter per minute?
The flow unit for taps, showers and medical oxygen.
What is a acre-foot per day?
Irrigation and reservoir release rates in the western United States.
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 L/min to ac ft/d in my head?
Plenty of people do this in their head: divide by 860 instead of using the exact factor 0.001167426999. At 100 that shortcut gives 0.11627907 acre-feet per day, off by 0.0004636 acre-feet per day or about 0.40%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
