About Converting Imperial quarts per Millisecond to Gallon per Days
Imperial quart 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 = imperial quarts per millisecond × 25940518.3909
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial quart per millisecond equals 1.1365225 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct imperial quart per millisecond-to-gallon per days factor of 25940518.3909.
Simple example
1 imp qt/ms × 25940518.39 = 25,940,518.39 gal/d
1 imperial quart per millisecond = 25,940,518.39 gallon per days.
Real-world example
60 imp qt/ms × 25940518.39 = 1,556,431,103 gal/d
60 imperial quarts per millisecond = 1,556,431,103 gallon per days.

Frequently asked questions
How many gallon per days are in 1 imperial quart per millisecond?
1 imperial quart per millisecond equals 25,940,518.39 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial quart per millisecond to gallon per days?
Multiply the imperial quart per millisecond value by 25940518.39. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to imperial quart per millisecond?
Use the reverse factor: 1 gallon per days equals 3.854973e-8 imperial quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/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 imperial quart per millisecond to gallon per days conversion exact?
Yes. Both imperial quart per millisecond and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 25940518.39 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.
