About Converting Metric cup per Seconds to Cubic Kilometer per Days
Metric cup per Seconds and Cubic Kilometer 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. Both are volumetric flow rate units.
Formula
cubic kilometer per days = metric cup per seconds × 2.16e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 metric cup per seconds equals 0.00025 base units, and 1 cubic kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct metric cup per seconds-to-cubic kilometer per days factor of 2.16e-8.
Simple example
1 metric cup/s × 2.16e-8 = 2.16e-8 km3/d
1 metric cup per seconds = 2.16e-8 cubic kilometer per days.
Real-world example
60 metric cup/s × 2.16e-8 = 0.000001296 km3/d
60 metric cup per seconds = 0.000001296 cubic kilometer per days.

Frequently asked questions
How many cubic kilometer per days are in 1 metric cup per seconds?
1 metric cup per seconds equals 2.16e-8 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert metric cup per seconds to cubic kilometer per days?
Multiply the metric cup per seconds value by 2.16e-8. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to metric cup per seconds?
Use the reverse factor: 1 cubic kilometer per days equals 46,296,296.3 metric cup per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric cup per seconds?
Metric cup per Seconds (metric cup/s) is a unit of flow rate.
What is a cubic kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the metric cup per seconds to cubic kilometer per days conversion exact?
Yes. Both metric cup per seconds and cubic kilometer per days are defined by fixed standards rather than physical artifacts, so the factor of 2.16e-8 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.
