This page converts US gallons per day into US gallons per minute using the factor 0.0006944443012, and shows the reverse figure alongside it. Both units measure volumetric flow, which is why one number does the whole job.
The rating unit for reverse-osmosis membranes and water demand. The US standard for pumps, irrigation and fixtures.
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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in US gallons per minute, so you can sanity-check whether your answer is a plausible size.
The formula
US gallons per day- The amount you are converting, in US gallons per day
0.000694444301194- The exact number of US gallons per minute in one US gallon per day
US gallons per minute- The converted result
How it works, step by step
- Enter the value in US gallons per day.
- It is multiplied by 0.000694444301194, the exact factor between the two units.
- The answer is shown in US gallons per minute, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
A fire hydrant: 1.37e+06 GPD in US gallons per minute
At 1.37e+06 GPD (a fire hydrant), the same quantity in US gallons per minute is 1.37e+06 × 0.000694444 = 951.389 GPM. One US gallon per day is 0.000694444 US gallons per minute, so the numbers shrink as expected.
A shower head: 3650 GPD in US gallons per minute
Take a shower head, roughly 3650 GPD. The conversion is a single multiplication — 3650 × 0.000694444 — giving 2.53472 GPM. Because the relationship is proportional, doubling the input doubles the answer to 5.06944 GPM.

Frequently asked questions
How many US gallons per minute are in one US gallon per day?
Exactly 0.000694444301194. 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 US gallons per day to US gallons per minute?
US gallons per minute = US gallons per day × 0.000694444301194. Reversed, US gallons per day = US gallons per minute ÷ 0.000694444301194, which is the same as multiplying by 1440.00029704.
Which is the bigger unit, the US gallon per day or the US gallon per minute?
The US gallon per minute. One US gallon per day is only 0.000694444 of a US gallon per minute, so it takes 1440 US gallons per day to make one US 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 US gallon per day?
The rating unit for reverse-osmosis membranes and water demand.
What is a US gallon per minute?
The US standard for pumps, irrigation and fixtures.
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 GPD to GPM in my head?
Plenty of people do this in their head: divide by 1400 instead of using the exact factor 0.0006944443012. At 100 that shortcut gives 0.071428571 US gallons per minute, off by 0.001984 US gallons per minute or about 2.86%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
