About Converting Megaliter per Days to Imperial gallons per Millisecond
Megaliter per Days and Imperial 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
imperial gallons per millisecond = megaliter per days × 0.00254594037383
This factor comes from each unit's defined relationship to the category's base unit: 1 megaliter per days equals 0.0115740740741 base units, and 1 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct megaliter per days-to-imperial gallon per millisecond factor of 0.00254594037383.
Simple example
1 ML/d × 0.002545940374 = 0.0025459404 imp gal/ms
1 megaliter per days = 0.0025459404 imperial gallons per millisecond.
Real-world example
60 ML/d × 0.002545940374 = 0.1527564224 imp gal/ms
60 megaliter per days = 0.1527564224 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 megaliter per days?
1 megaliter per days equals 0.0025459404 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert megaliter per days to imperial gallon per millisecond?
Multiply the megaliter per days value by 0.002545940374. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to megaliter per days?
Use the reverse factor: 1 imperial gallon per millisecond equals 392.782176 megaliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a megaliter per days?
Megaliter per Days (ML/d) is a unit of flow rate.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the megaliter per days to imperial gallon per millisecond conversion exact?
Yes. Both megaliter per days and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.002545940374 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.
