About Converting Liter per Days to Imperial pint per Years
Liter 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 = liter per days × 642.736945375
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per days equals 1.157407e-8 base units, and 1 imperial pint per years equals 1.800748e-11 base units, so dividing one by the other gives the direct liter per days-to-imperial pint per years factor of 642.736945375.
Simple example
1 L/d × 642.7369454 = 642.7369454 imp pt/yr
1 liter per days = 642.7369454 imperial pint per years.
Real-world example
60 L/d × 642.7369454 = 38,564.21672 imp pt/yr
60 liter per days = 38,564.21672 imperial pint per years.

Frequently asked questions
How many imperial pint per years are in 1 liter per days?
1 liter per days equals 642.7369454 imperial pint per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per days to imperial pint per years?
Multiply the liter per days value by 642.7369454. The converter above does this instantly to whatever precision you set.
How do I convert imperial pint per years back to liter per days?
Use the reverse factor: 1 imperial pint per years equals 0.0015558465 liter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per days?
Liter per Days (L/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 liter per days to imperial pint per years conversion exact?
Yes. Both liter per days and imperial pint per years are defined by fixed standards rather than physical artifacts, so the factor of 642.7369454 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.
