About Converting Cup per Days to Metric cup per Years
Cup per Days and Metric cup 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
metric cup per years = cup per days × 345.648315879
This factor comes from each unit's defined relationship to the category's base unit: 1 cup per days equals 2.73829e-9 base units, and 1 metric cup per years equals 7.922185e-12 base units, so dividing one by the other gives the direct cup per days-to-metric cup per years factor of 345.648315879.
Simple example
1 cup/d × 345.6483159 = 345.6483159 metric cup/yr
1 cup per days = 345.6483159 metric cup per years.
Real-world example
60 cup/d × 345.6483159 = 20,738.89895 metric cup/yr
60 cup per days = 20,738.89895 metric cup per years.

Frequently asked questions
How many metric cup per years are in 1 cup per days?
1 cup per days equals 345.6483159 metric cup per years, using the exact defined conversion factor rather than an estimate.

How do I convert metric cup per years back to cup per days?
Use the reverse factor: 1 metric cup per years equals 0.0028931141 cup per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
What is a metric cup per years?
Metric cup per Years (metric cup/yr) is a unit of flow rate.
Is the cup per days to metric cup per years conversion exact?
Yes. Both cup per days and metric cup per years are defined by fixed standards rather than physical artifacts, so the factor of 345.6483159 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.
