About Converting Quart per Days to Cubic Meter per Years
Quart per Days and Cubic Meter 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
cubic meter per years = quart per days × 0.345648315879
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per days equals 1.095316e-8 base units, and 1 cubic meter per years equals 3.168874e-8 base units, so dividing one by the other gives the direct quart per days-to-cubic meter per years factor of 0.345648315879.
Simple example
1 qt/d × 0.3456483159 = 0.3456483159 m3/yr
1 quart per days = 0.3456483159 cubic meter per years.
Real-world example
60 qt/d × 0.3456483159 = 20.73889895 m3/yr
60 quart per days = 20.73889895 cubic meter per years.

Frequently asked questions
How many cubic meter per years are in 1 quart per days?
1 quart per days equals 0.3456483159 cubic meter per years, using the exact defined conversion factor rather than an estimate.
How do I convert quart per days to cubic meter per years?
Multiply the quart per days value by 0.3456483159. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per years back to quart per days?
Use the reverse factor: 1 cubic meter per years equals 2.893114053 quart per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per days?
Quart per Days (qt/d) is a unit of flow rate.
What is a cubic meter per years?
Cubic Meter per Years (m3/yr) is a unit of flow rate.
Is the quart per days to cubic meter per years conversion exact?
Yes. Both quart per days and cubic meter per years are defined by fixed standards rather than physical artifacts, so the factor of 0.3456483159 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.
