About Converting Fluid ounces per Millisecond to Gallon per Days
Fluid ounce per Millisecond and Gallon per Days both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
gallon per days = fluid ounces per millisecond × 675000
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce per millisecond equals 0.0295735295625 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct fluid ounce per millisecond-to-gallon per days factor of 675000.
Simple example
1 fl oz/ms × 675000 = 675,000 gal/d
1 fluid ounce per millisecond = 675,000 gallon per days.
Real-world example
60 fl oz/ms × 675000 = 40,500,000 gal/d
60 fluid ounces per millisecond = 40,500,000 gallon per days.

Frequently asked questions
How many gallon per days are in 1 fluid ounce per millisecond?
1 fluid ounce per millisecond equals 675,000 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert fluid ounce per millisecond to gallon per days?
Multiply the fluid ounce per millisecond value by 675000. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to fluid ounce per millisecond?
Use the reverse factor: 1 gallon per days equals 0.0000014815 fluid ounces per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a fluid ounce per millisecond?
Fluid ounce per Millisecond (fl oz/ms) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the fluid ounce per millisecond to gallon per days conversion exact?
Yes. Both fluid ounce per millisecond and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 675000 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
