About Converting Gallon per Days to Imperial fluid ounces per Millisecond
Gallon per Days and Imperial fluid ounce per Millisecond 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
imperial fluid ounces per millisecond = gallon per days × 0.00000154198923079
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 imperial fluid ounce per millisecond equals 0.0284130625 base units, so dividing one by the other gives the direct gallon per days-to-imperial fluid ounce per millisecond factor of 0.00000154198923079.
Simple example
1 gal/d × 0.000001541989231 = 0.000001542 imp fl oz/ms
1 gallon per days = 0.000001542 imperial fluid ounces per millisecond.
Real-world example
60 gal/d × 0.000001541989231 = 0.0000925194 imp fl oz/ms
60 gallon per days = 0.0000925194 imperial fluid ounces per millisecond.

Frequently asked questions
How many imperial fluid ounces per millisecond are in 1 gallon per days?
1 gallon per days equals 0.000001542 imperial fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to imperial fluid ounce per millisecond?
Multiply the gallon per days value by 0.000001541989231. The converter above does this instantly to whatever precision you set.
How do I convert imperial fluid ounce per millisecond back to gallon per days?
Use the reverse factor: 1 imperial fluid ounce per millisecond equals 648,512.9598 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a imperial fluid ounce per millisecond?
Imperial fluid ounce per Millisecond (imp fl oz/ms) is a unit of flow rate.
Is the gallon per days to imperial fluid ounce per millisecond conversion exact?
Yes. Both gallon per days and imperial fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000001541989231 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.
