About Converting Quart per Seconds to Cubic inches per Millisecond
Quart per Seconds and Cubic inch per Millisecond 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 inches per millisecond = quart per seconds × 0.05775
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per seconds equals 0.000946352946 base units, and 1 cubic inch per millisecond equals 0.016387064 base units, so dividing one by the other gives the direct quart per seconds-to-cubic inch per millisecond factor of 0.05775.
Simple example
1 qt/s × 0.05775 = 0.05775 in3/ms
1 quart per seconds = 0.05775 cubic inches per millisecond.
Real-world example
60 qt/s × 0.05775 = 3.465 in3/ms
60 quart per seconds = 3.465 cubic inches per millisecond.

Frequently asked questions
How many cubic inches per millisecond are in 1 quart per seconds?
1 quart per seconds equals 0.05775 cubic inches per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert quart per seconds to cubic inch per millisecond?
Multiply the quart per seconds value by 0.05775. The converter above does this instantly to whatever precision you set.
How do I convert cubic inch per millisecond back to quart per seconds?
Use the reverse factor: 1 cubic inch per millisecond equals 17.31601732 quart per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per seconds?
Quart per Seconds (qt/s) is a unit of flow rate.
What is a cubic inch per millisecond?
Cubic inch per Millisecond (in3/ms) is a unit of flow rate.
Is the quart per seconds to cubic inch per millisecond conversion exact?
Yes. Both quart per seconds and cubic inch per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.05775 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.
