About Converting Cubic inch per Seconds to Cubic Millimeters per Millisecond
Cubic inch per Seconds and Cubic Millimeter 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 millimeters per millisecond = cubic inch per seconds × 16.387064
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 millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct cubic inch per seconds-to-cubic millimeter per millisecond factor of 16.387064.
Simple example
1 in3/s × 16.387064 = 16.387064 mm3/ms
1 cubic inch per seconds = 16.387064 cubic millimeters per millisecond.
Real-world example
60 in3/s × 16.387064 = 983.22384 mm3/ms
60 cubic inch per seconds = 983.22384 cubic millimeters per millisecond.

Frequently asked questions
How many cubic millimeters per millisecond are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 16.387064 cubic millimeters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to cubic millimeter per millisecond?
Multiply the cubic inch per seconds value by 16.387064. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per millisecond back to cubic inch per seconds?
Use the reverse factor: 1 cubic millimeter per millisecond equals 0.0610237441 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 millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the cubic inch per seconds to cubic millimeter per millisecond conversion exact?
Yes. Both cubic inch per seconds and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 16.387064 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.
