About Converting Pint per Hours to Liter per Years
Pint per Hours and Liter 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
liter per years = pint per hours × 4147.77979055
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per hours equals 1.314379e-7 base units, and 1 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct pint per hours-to-liter per years factor of 4147.77979055.
Simple example
1 pt/h × 4147.779791 = 4,147.779791 L/yr
1 pint per hours = 4,147.779791 liter per years.
Real-world example
60 pt/h × 4147.779791 = 248,866.7874 L/yr
60 pint per hours = 248,866.7874 liter per years.

Frequently asked questions
How many liter per years are in 1 pint per hours?
1 pint per hours equals 4,147.779791 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert pint per hours to liter per years?
Multiply the pint per hours value by 4147.779791. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to pint per hours?
Use the reverse factor: 1 liter per years equals 0.0002410928 pint per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per hours?
Pint per Hours (pt/h) is a unit of flow rate.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
Is the pint per hours to liter per years conversion exact?
Yes. Both pint per hours and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 4147.779791 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.
