About Converting Gallon per Hours to Deciliters per Millisecond
Gallon per Hours and Deciliter 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
deciliters per millisecond = gallon per hours × 0.0000105150327333
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 deciliter per millisecond equals 0.1 base units, so dividing one by the other gives the direct gallon per hours-to-deciliter per millisecond factor of 0.0000105150327333.
Simple example
1 gal/h × 0.00001051503273 = 0.000010515 dL/ms
1 gallon per hours = 0.000010515 deciliters per millisecond.
Real-world example
60 gal/h × 0.00001051503273 = 0.000630902 dL/ms
60 gallon per hours = 0.000630902 deciliters per millisecond.

Frequently asked questions
How many deciliters per millisecond are in 1 gallon per hours?
1 gallon per hours equals 0.000010515 deciliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to deciliter per millisecond?
Multiply the gallon per hours value by 0.00001051503273. The converter above does this instantly to whatever precision you set.
How do I convert deciliter per millisecond back to gallon per hours?
Use the reverse factor: 1 deciliter per millisecond equals 95,101.93885 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 deciliter per millisecond?
Deciliter per Millisecond (dL/ms) is a unit of flow rate.
Is the gallon per hours to deciliter per millisecond conversion exact?
Yes. Both gallon per hours and deciliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00001051503273 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.
