About Converting Milliliter per Years to Quart per Hours
Milliliter per Years and Quart per Hours 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
quart per hours = milliliter per years × 1.205464e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per years equals 3.168874e-14 base units, and 1 quart per hours equals 2.628758e-7 base units, so dividing one by the other gives the direct milliliter per years-to-quart per hours factor of 1.205464e-7.
Simple example
1 mL/yr × 1.205464e-7 = 1.205464e-7 qt/h
1 milliliter per years = 1.205464e-7 quart per hours.
Real-world example
60 mL/yr × 1.205464e-7 = 0.0000072328 qt/h
60 milliliter per years = 0.0000072328 quart per hours.

Frequently asked questions
How many quart per hours are in 1 milliliter per years?
1 milliliter per years equals 1.205464e-7 quart per hours, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per years to quart per hours?
Multiply the milliliter per years value by 1.205464e-7. The converter above does this instantly to whatever precision you set.
How do I convert quart per hours back to milliliter per years?
Use the reverse factor: 1 quart per hours equals 8,295,559.581 milliliter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per years?
Milliliter per Years (mL/yr) is a unit of flow rate.
What is a quart per hours?
Quart per Hours (qt/h) is a unit of flow rate.
Is the milliliter per years to quart per hours conversion exact?
Yes. Both milliliter per years and quart per hours are defined by fixed standards rather than physical artifacts, so the factor of 1.205464e-7 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.
