About Converting Metric cup per Seconds to Cubic Kilometer per Seconds
Metric cup per Seconds and Cubic Kilometer per Seconds 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 seconds = metric cup per seconds × 2.5e-13
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 seconds equals 1000000000 base units, so dividing one by the other gives the direct metric cup per seconds-to-cubic kilometer per seconds factor of 2.5e-13.
Simple example
1 metric cup/s × 2.5e-13 = 2.5e-13 km3/s
1 metric cup per seconds = 2.5e-13 cubic kilometer per seconds.
Real-world example
60 metric cup/s × 2.5e-13 = 1.5e-11 km3/s
60 metric cup per seconds = 1.5e-11 cubic kilometer per seconds.

Frequently asked questions
How many cubic kilometer per seconds are in 1 metric cup per seconds?
1 metric cup per seconds equals 2.5e-13 cubic kilometer per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert metric cup per seconds to cubic kilometer per seconds?
Multiply the metric cup per seconds value by 2.5e-13. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per seconds back to metric cup per seconds?
Use the reverse factor: 1 cubic kilometer per seconds equals 4e+12 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 seconds?
Cubic Kilometer per Seconds (km3/s) is a unit of flow rate.
Is the metric cup per seconds to cubic kilometer per seconds conversion exact?
Yes. Both metric cup per seconds and cubic kilometer per seconds are defined by fixed standards rather than physical artifacts, so the factor of 2.5e-13 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.
