About Converting Pint per Years to Quarts per Millisecond
Pint per Years and Quart per Millisecond 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
quarts per millisecond = pint per years × 1.584437e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 pint per years equals 1.499437e-11 base units, and 1 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct pint per years-to-quart per millisecond factor of 1.584437e-11.
Simple example
1 pt/yr × 1.584437e-11 = 1.584437e-11 qt/ms
1 pint per years = 1.584437e-11 quarts per millisecond.
Real-world example
60 pt/yr × 1.584437e-11 = 9.506622e-10 qt/ms
60 pint per years = 9.506622e-10 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 pint per years?
1 pint per years equals 1.584437e-11 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert pint per years to quart per millisecond?
Multiply the pint per years value by 1.584437e-11. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to pint per years?
Use the reverse factor: 1 quart per millisecond equals 63,113,904,000 pint per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a pint per years?
Pint per Years (pt/yr) is a unit of flow rate.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the pint per years to quart per millisecond conversion exact?
Yes. Both pint per years and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.584437e-11 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.
