About Converting Milliliter per Days to Imperial gallon per Days
Milliliter per Days and Imperial 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
imperial gallon per days = milliliter per days × 0.000219969248299
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per days equals 1.157407e-11 base units, and 1 imperial gallon per days equals 5.261678e-8 base units, so dividing one by the other gives the direct milliliter per days-to-imperial gallon per days factor of 0.000219969248299.
Simple example
1 mL/d × 0.0002199692483 = 0.0002199692 imp gal/d
1 milliliter per days = 0.0002199692 imperial gallon per days.
Real-world example
60 mL/d × 0.0002199692483 = 0.0131981549 imp gal/d
60 milliliter per days = 0.0131981549 imperial gallon per days.

Frequently asked questions
How many imperial gallon per days are in 1 milliliter per days?
1 milliliter per days equals 0.0002199692 imperial gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to imperial gallon per days?
Multiply the milliliter per days value by 0.0002199692483. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per days back to milliliter per days?
Use the reverse factor: 1 imperial gallon per days equals 4,546.09 milliliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per days?
Milliliter per Days (mL/d) is a unit of flow rate.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
Is the milliliter per days to imperial gallon per days conversion exact?
Yes. Both milliliter per days and imperial gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0002199692483 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.
