About Converting Gallon per Days to Imperial pint per Days
Gallon per Days and Imperial pint 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
imperial pint per days = gallon per days × 6.66139347703
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 days equals 6.577098e-9 base units, so dividing one by the other gives the direct gallon per days-to-imperial pint per days factor of 6.66139347703.
Simple example
1 gal/d × 6.661393477 = 6.661393477 imp pt/d
1 gallon per days = 6.661393477 imperial pint per days.
Real-world example
60 gal/d × 6.661393477 = 399.6836086 imp pt/d
60 gallon per days = 399.6836086 imperial pint per days.

How do I convert imperial pint per days back to gallon per days?
Use the reverse factor: 1 imperial pint per days equals 0.1501187407 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 days?
Imperial pint per Days (imp pt/d) is a unit of flow rate.
Is the gallon per days to imperial pint per days conversion exact?
Yes. Both gallon per days and imperial pint per days are defined by fixed standards rather than physical artifacts, so the factor of 6.661393477 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.
