About Converting Cubic Kilometer per Weeks to Cup per Seconds
Cubic Kilometer per Weeks and Cup 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
cup per seconds = cubic kilometer per weeks × 6988678.63381
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic kilometer per weeks equals 1653.43915344 base units, and 1 cup per seconds equals 0.0002365882365 base units, so dividing one by the other gives the direct cubic kilometer per weeks-to-cup per seconds factor of 6988678.63381.
Simple example
1 km3/wk × 6988678.634 = 6,988,678.634 cup/s
1 cubic kilometer per weeks = 6,988,678.634 cup per seconds.
Real-world example
60 km3/wk × 6988678.634 = 419,320,718 cup/s
60 cubic kilometer per weeks = 419,320,718 cup per seconds.

Frequently asked questions
How many cup per seconds are in 1 cubic kilometer per weeks?
1 cubic kilometer per weeks equals 6,988,678.634 cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic kilometer per weeks to cup per seconds?
Multiply the cubic kilometer per weeks value by 6988678.634. The converter above does this instantly to whatever precision you set.
How do I convert cup per seconds back to cubic kilometer per weeks?
Use the reverse factor: 1 cup per seconds equals 1.430886e-7 cubic kilometer per weeks. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic kilometer per weeks?
Cubic Kilometer per Weeks (km3/wk) is a unit of flow rate.
What is a cup per seconds?
Cup per Seconds (cup/s) is a unit of flow rate.
Is the cubic kilometer per weeks to cup per seconds conversion exact?
Yes. Both cubic kilometer per weeks and cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 6988678.634 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.
