About Converting Cubic Meter per Seconds to Cup per Days
Cubic Meter per Seconds and Cup per Days 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. Cubic Meter per Seconds is most often used for used by hydrologists and water-resource engineers internationally to report river and reservoir discharge at large scales.
Formula
cup per days = cubic meter per seconds × 365191445.18
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per seconds equals 1 base unit, and 1 cup per days equals 2.73829e-9 base units, so dividing one by the other gives the direct cubic meter per seconds-to-cup per days factor of 365191445.18.
Simple example
1 m3/s × 365191445.2 = 365,191,445.2 cup/d
1 cubic meter per seconds = 365,191,445.2 cup per days.
Real-world example
60 m3/s × 365191445.2 = 21,911,486,710 cup/d
60 cubic meter per seconds = 21,911,486,710 cup per days.

Frequently asked questions
How many cup per days are in 1 cubic meter per seconds?
1 cubic meter per seconds equals 365,191,445.2 cup per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per seconds to cup per days?
Multiply the cubic meter per seconds value by 365191445.2. The converter above does this instantly to whatever precision you set.
How do I convert cup per days back to cubic meter per seconds?
Use the reverse factor: 1 cup per days equals 2.73829e-9 cubic meter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
What is a cup per days?
Cup per Days (cup/d) is a unit of flow rate.
Is the cubic meter per seconds to cup per days conversion exact?
Yes. Both cubic meter per seconds and cup per days are defined by fixed standards rather than physical artifacts, so the factor of 365191445.2 used above is exact to as many digits as you choose to display.
Where is the cubic meter per seconds still used today?
Used internationally in hydrology and large-scale water-resource engineering
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.
