About Converting Milliliter per Days to Imperial pint per Years
Milliliter per Days and Imperial pint per Years 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 years = milliliter per days × 0.642736945375
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 pint per years equals 1.800748e-11 base units, so dividing one by the other gives the direct milliliter per days-to-imperial pint per years factor of 0.642736945375.
Simple example
1 mL/d × 0.6427369454 = 0.6427369454 imp pt/yr
1 milliliter per days = 0.6427369454 imperial pint per years.
Real-world example
60 mL/d × 0.6427369454 = 38.56421672 imp pt/yr
60 milliliter per days = 38.56421672 imperial pint per years.

Frequently asked questions
How many imperial pint per years are in 1 milliliter per days?
1 milliliter per days equals 0.6427369454 imperial pint per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to imperial pint per years?
Multiply the milliliter per days value by 0.6427369454. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per years back to milliliter per days?
Use the reverse factor: 1 imperial pint per years equals 1.555846458 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 pint per years?
Imperial pint per Years (imp pt/yr) is a unit of flow rate.
Is the milliliter per days to imperial pint per years conversion exact?
Yes. Both milliliter per days and imperial pint per years are defined by fixed standards rather than physical artifacts, so the factor of 0.6427369454 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.
