To convert milliliters per minute to acre-feet per day, multiply by 1.167426999e-06. 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.
Irrigation and reservoir release rates in the western United States. Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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
milliliters per minute- The amount you are converting, in milliliters per minute
1.1674269991e-06- The exact number of acre-feet per day in one milliliter per minute
acre-feet per day- The converted result
How it works, step by step
- Enter the value in milliliters per minute.
- It is multiplied by 1.1674269991e-06, 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
A dripping tap: 6 mL/min in acre-feet per day
Take a dripping tap, roughly 6 mL/min. The conversion is a single multiplication — 6 × 1.16743e-06 — giving 7.00456e-06 ac ft/d. Because the relationship is proportional, doubling the input doubles the answer to 1.40091e-05 ac ft/d.
A shower head: 9600 mL/min in acre-feet per day
Take a shower head, roughly 9600 mL/min. The conversion is a single multiplication — 9600 × 1.16743e-06 — giving 0.0112073 ac ft/d. Because the relationship is proportional, doubling the input doubles the answer to 0.0224146 ac ft/d.
How to read your score
Frequently asked questions
How many acre-feet per day are in one milliliter per minute?
Exactly 1.1674269991e-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 milliliters per minute to acre-feet per day?
acre-feet per day = milliliters per minute × 1.1674269991e-06. Reversed, milliliters per minute = acre-feet per day ÷ 1.1674269991e-06, which is the same as multiplying by 856,584.60938.
Which is the bigger unit, the milliliter per minute or the acre-foot per day?
The acre-foot per day. One milliliter per minute is only 1.16743e-06 of a acre-foot per day, so it takes 856,585 milliliters 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 milliliter per minute?
Laboratory and infusion flow: HPLC pumps and syringe drivers are set in mL/min.
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 mL/min to ac ft/d in my head?
Plenty of people do this in their head: divide by 860,000 instead of using the exact factor 0.000001. At 100 that shortcut gives 0.00011627907 acre-feet per day, off by 0.000000 acre-feet per day or about 0.40%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
