About Converting Gallon per Days to Imperial pint per Hours
Gallon per Days and Imperial pint 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
imperial pint per hours = gallon per days × 0.277558061543
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 pint per hours equals 1.578503e-7 base units, so dividing one by the other gives the direct gallon per days-to-imperial pint per hours factor of 0.277558061543.
Simple example
1 gal/d × 0.2775580615 = 0.2775580615 imp pt/h
1 gallon per days = 0.2775580615 imperial pint per hours.
Real-world example
60 gal/d × 0.2775580615 = 16.65348369 imp pt/h
60 gallon per days = 16.65348369 imperial pint per hours.

How do I convert imperial pint per hours back to gallon per days?
Use the reverse factor: 1 imperial pint per hours equals 3.602849777 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 pint per hours?
Imperial pint per Hours (imp pt/h) is a unit of flow rate.
Is the gallon per days to imperial pint per hours conversion exact?
Yes. Both gallon per days and imperial pint per hours are defined by fixed standards rather than physical artifacts, so the factor of 0.2775580615 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.
