About Converting Cubic inch per Seconds to Cubic yard per Seconds
Cubic inch per Seconds and Cubic yard 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 yard per seconds = cubic inch per seconds × 0.0000214334705075
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 cubic yard per seconds equals 0.764554857984 base units, so dividing one by the other gives the direct cubic inch per seconds-to-cubic yard per seconds factor of 0.0000214334705075.
Simple example
1 in3/s × 0.00002143347051 = 0.0000214335 yd3/s
1 cubic inch per seconds = 0.0000214335 cubic yard per seconds.
Real-world example
60 in3/s × 0.00002143347051 = 0.0012860082 yd3/s
60 cubic inch per seconds = 0.0012860082 cubic yard per seconds.

Frequently asked questions
How many cubic yard per seconds are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 0.0000214335 cubic yard per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to cubic yard per seconds?
Multiply the cubic inch per seconds value by 0.00002143347051. The converter above does this instantly to whatever precision you set.
How do I convert cubic yard per seconds back to cubic inch per seconds?
Use the reverse factor: 1 cubic yard per seconds equals 46,656 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 cubic yard per seconds?
Cubic yard per Seconds (yd3/s) is a unit of flow rate.
Is the cubic inch per seconds to cubic yard per seconds conversion exact?
Yes. Both cubic inch per seconds and cubic yard per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.00002143347051 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.
