About Converting Cubic inch per Seconds to Liters per Millisecond
Cubic inch per Seconds and Liter 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
liters per millisecond = cubic inch per seconds × 0.000016387064
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 liter per millisecond equals 1 base unit, so dividing one by the other gives the direct cubic inch per seconds-to-liter per millisecond factor of 0.000016387064.
Simple example
1 in3/s × 0.000016387064 = 0.0000163871 L/ms
1 cubic inch per seconds = 0.0000163871 liters per millisecond.
Real-world example
60 in3/s × 0.000016387064 = 0.0009832238 L/ms
60 cubic inch per seconds = 0.0009832238 liters per millisecond.

Frequently asked questions
How many liters per millisecond are in 1 cubic inch per seconds?
1 cubic inch per seconds equals 0.0000163871 liters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic inch per seconds to liter per millisecond?
Multiply the cubic inch per seconds value by 0.000016387064. The converter above does this instantly to whatever precision you set.
How do I convert liter per millisecond back to cubic inch per seconds?
Use the reverse factor: 1 liter per millisecond equals 61,023.74409 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 liter per millisecond?
Liter per Millisecond (L/ms) is a unit of flow rate.
Is the cubic inch per seconds to liter per millisecond conversion exact?
Yes. Both cubic inch per seconds and liter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000016387064 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.
