About Converting Gallons per Millisecond to Hectoliter per Seconds
Gallon per Millisecond and Hectoliter per Seconds 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
hectoliter per seconds = gallons per millisecond × 37.85411784
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 hectoliter per seconds equals 0.1 base units, so dividing one by the other gives the direct gallon per millisecond-to-hectoliter per seconds factor of 37.85411784.
Simple example
1 gal/ms × 37.85411784 = 37.85411784 hL/s
1 gallon per millisecond = 37.85411784 hectoliter per seconds.
Real-world example
60 gal/ms × 37.85411784 = 2,271.24707 hL/s
60 gallons per millisecond = 2,271.24707 hectoliter per seconds.

Frequently asked questions
How many hectoliter per seconds are in 1 gallon per millisecond?
1 gallon per millisecond equals 37.85411784 hectoliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to hectoliter per seconds?
Multiply the gallon per millisecond value by 37.85411784. The converter above does this instantly to whatever precision you set.
How do I convert hectoliter per seconds back to gallon per millisecond?
Use the reverse factor: 1 hectoliter per seconds equals 0.0264172052 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a hectoliter per seconds?
Hectoliter per Seconds (hL/s) is a unit of flow rate.
Is the gallon per millisecond to hectoliter per seconds conversion exact?
Yes. Both gallon per millisecond and hectoliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 37.85411784 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.
