About Converting Gallon per Days to Quart per Hours
Gallon per Days and Quart per Hours 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
quart per hours = gallon per days × 0.166666666667
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 quart per hours equals 2.628758e-7 base units, so dividing one by the other gives the direct gallon per days-to-quart per hours factor of 0.166666666667.
Simple example
1 gal/d × 0.1666666667 = 0.1666666667 qt/h
1 gallon per days = 0.1666666667 quart per hours.
Real-world example
60 gal/d × 0.1666666667 = 10 qt/h
60 gallon per days = 10 quart per hours.

Frequently asked questions
How many quart per hours are in 1 gallon per days?
1 gallon per days equals 0.1666666667 quart per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to quart per hours?
Multiply the gallon per days value by 0.1666666667. The converter above does this instantly to whatever precision you set.
How do I convert quart per hours back to gallon per days?
Use the reverse factor: 1 quart per hours equals 6 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 quart per hours?
Quart per Hours (qt/h) is a unit of flow rate.
Is the gallon per days to quart per hours conversion exact?
Yes. Both gallon per days and quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.1666666667 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.
