About Converting Gallon per Seconds to Kiloliters per Millisecond
Gallon per Seconds and Kiloliter 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
kiloliters per millisecond = gallon per seconds × 0.000003785411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 kiloliter per millisecond equals 1000 base units, so dividing one by the other gives the direct gallon per seconds-to-kiloliter per millisecond factor of 0.000003785411784.
Simple example
1 gal/s × 0.000003785411784 = 0.0000037854 kL/ms
1 gallon per seconds = 0.0000037854 kiloliters per millisecond.
Real-world example
60 gal/s × 0.000003785411784 = 0.0002271247 kL/ms
60 gallon per seconds = 0.0002271247 kiloliters per millisecond.

Frequently asked questions
How many kiloliters per millisecond are in 1 gallon per seconds?
1 gallon per seconds equals 0.0000037854 kiloliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to kiloliter per millisecond?
Multiply the gallon per seconds value by 0.000003785411784. The converter above does this instantly to whatever precision you set.
How do I convert kiloliter per millisecond back to gallon per seconds?
Use the reverse factor: 1 kiloliter per millisecond equals 264,172.0524 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a kiloliter per millisecond?
Kiloliter per Millisecond (kL/ms) is a unit of flow rate.
Is the gallon per seconds to kiloliter per millisecond conversion exact?
Yes. Both gallon per seconds and kiloliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000003785411784 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.
