About Converting Cubic inch per Seconds to Metric cup per Seconds
Cubic inch per Seconds and Metric 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
metric cup per seconds = cubic inch per seconds × 0.065548256
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic inch per seconds equals 0.000016387064 base units, and 1 metric cup per seconds equals 0.00025 base units, so dividing one by the other gives the direct cubic inch per seconds-to-metric cup per seconds factor of 0.065548256.
Simple example
1 in3/s × 0.065548256 = 0.065548256 metric cup/s
1 cubic inch per seconds = 0.065548256 metric cup per seconds.
Real-world example
60 in3/s × 0.065548256 = 3.93289536 metric cup/s
60 cubic inch per seconds = 3.93289536 metric cup per seconds.

Frequently asked questions
How many metric cup per seconds are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 0.065548256 metric cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to metric cup per seconds?
Multiply the cubic inch per seconds value by 0.065548256. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per seconds back to cubic inch per seconds?
Use the reverse factor: 1 metric cup per seconds equals 15.25593602 cubic inch per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic inch per seconds?
Cubic inch per Seconds (in3/s) is a unit of flow rate.
What is a metric cup per seconds?
Metric cup per Seconds (metric cup/s) is a unit of flow rate.
Is the cubic inch per seconds to metric cup per seconds conversion exact?
Yes. Both cubic inch per seconds and metric cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.065548256 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.
