About Converting Cubic inch per Seconds to Quarts per Millisecond
Cubic inch per Seconds and Quart 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
quarts per millisecond = cubic inch per seconds × 0.000017316017316
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 quart per millisecond equals 0.946352946 base units, so dividing one by the other gives the direct cubic inch per seconds-to-quart per millisecond factor of 0.000017316017316.
Simple example
1 in3/s × 0.00001731601732 = 0.000017316 qt/ms
1 cubic inch per seconds = 0.000017316 quarts per millisecond.
Real-world example
60 in3/s × 0.00001731601732 = 0.001038961 qt/ms
60 cubic inch per seconds = 0.001038961 quarts per millisecond.

Frequently asked questions
How many quarts per millisecond are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 0.000017316 quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to quart per millisecond?
Multiply the cubic inch per seconds value by 0.00001731601732. The converter above does this instantly to whatever precision you set.
How do I convert quart per millisecond back to cubic inch per seconds?
Use the reverse factor: 1 quart per millisecond equals 57,750 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 quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
Is the cubic inch per seconds to quart per millisecond conversion exact?
Yes. Both cubic inch per seconds and quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00001731601732 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.
