About Converting Gallon per Hours to Decaliters per Millisecond
Gallon per Hours and Decaliter 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
decaliters per millisecond = gallon per hours × 1.051503e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 decaliter per millisecond equals 10 base units, so dividing one by the other gives the direct gallon per hours-to-decaliter per millisecond factor of 1.051503e-7.
Simple example
1 gal/h × 1.051503e-7 = 1.051503e-7 daL/ms
1 gallon per hours = 1.051503e-7 decaliters per millisecond.
Real-world example
60 gal/h × 1.051503e-7 = 0.000006309 daL/ms
60 gallon per hours = 0.000006309 decaliters per millisecond.

Frequently asked questions
How many decaliters per millisecond are in 1 gallon per hours?
1 gallon per hours equals 1.051503e-7 decaliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to decaliter per millisecond?
Multiply the gallon per hours value by 1.051503e-7. The converter above does this instantly to whatever precision you set.
How do I convert decaliter per millisecond back to gallon per hours?
Use the reverse factor: 1 decaliter per millisecond equals 9,510,193.885 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a decaliter per millisecond?
Decaliter per Millisecond (daL/ms) is a unit of flow rate.
Is the gallon per hours to decaliter per millisecond conversion exact?
Yes. Both gallon per hours and decaliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.051503e-7 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.
