About Converting Hectoliter per Decades to Gallons per Millisecond
Hectoliter per Decades and Gallon 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
gallons per millisecond = hectoliter per decades × 8.371279e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoliter per decades equals 3.168874e-10 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct hectoliter per decades-to-gallon per millisecond factor of 8.371279e-11.
Simple example
1 hL/decade × 8.371279e-11 = 8.371279e-11 gal/ms
1 hectoliter per decades = 8.371279e-11 gallons per millisecond.
Real-world example
60 hL/decade × 8.371279e-11 = 5.022767e-9 gal/ms
60 hectoliter per decades = 5.022767e-9 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 hectoliter per decades?
1 hectoliter per decades equals 8.371279e-11 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert hectoliter per decades to gallon per millisecond?
Multiply the hectoliter per decades value by 8.371279e-11. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to hectoliter per decades?
Use the reverse factor: 1 gallon per millisecond equals 11,945,605,800 hectoliter per decades. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoliter per decades?
Hectoliter per Decades (hL/decade) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the hectoliter per decades to gallon per millisecond conversion exact?
Yes. Both hectoliter per decades and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 8.371279e-11 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.
