About Converting Imperial pint per Days to Gallon per Days
Imperial pint per Days 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 pint per days × 0.150118740688
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial pint per days equals 6.577098e-9 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct imperial pint per days-to-gallon per days factor of 0.150118740688.
Simple example
1 imp pt/d × 0.1501187407 = 0.1501187407 gal/d
1 imperial pint per days = 0.1501187407 gallon per days.
Real-world example
60 imp pt/d × 0.1501187407 = 9.007124441 gal/d
60 imperial pint per days = 9.007124441 gallon per days.

What is a imperial pint per days?
Imperial pint per Days (imp pt/d) 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 pint per days to gallon per days conversion exact?
Yes. Both imperial pint per days and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 0.1501187407 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.
