About Converting Gallon per Days to Megaliter per Hours
Gallon per Days and Megaliter per Hours 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
megaliter per hours = gallon per days × 1.577255e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per days equals 4.381264e-8 base units, and 1 megaliter per hours equals 0.277777777778 base units, so dividing one by the other gives the direct gallon per days-to-megaliter per hours factor of 1.577255e-7.
Simple example
1 gal/d × 1.577255e-7 = 1.577255e-7 ML/h
1 gallon per days = 1.577255e-7 megaliter per hours.
Real-world example
60 gal/d × 1.577255e-7 = 0.0000094635 ML/h
60 gallon per days = 0.0000094635 megaliter per hours.

Frequently asked questions
How many megaliter per hours are in 1 gallon per days?
1 gallon per days equals 1.577255e-7 megaliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per days to megaliter per hours?
Multiply the gallon per days value by 1.577255e-7. The converter above does this instantly to whatever precision you set.
How do I convert megaliter per hours back to gallon per days?
Use the reverse factor: 1 megaliter per hours equals 6,340,129.257 gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
What is a megaliter per hours?
Megaliter per Hours (ML/h) is a unit of flow rate.
Is the gallon per days to megaliter per hours conversion exact?
Yes. Both gallon per days and megaliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 1.577255e-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.
