Frequently asked questions
What is the source unit in this conversion?
The source unit is imperial gallons per day (imp gal/d). The Imperial Gallon (imp gal) is a unit of volume. The Day (d) is a unit of time.
What is the destination unit in this conversion?
The destination unit is cubic millimeters per hour (mm3/h). The Cubic Millimeter (mm3) is a unit of volume. The Hour (h) is a unit of time.
How do I convert imperial gallons per day to cubic millimeters per hour?
Multiply the imperial gallons per day value by 189420 to get cubic millimeters per hour. For example, 10 imp gal/d × 189420 = 1.8942e+6 mm3/h.
Is the imperial gallons per day to cubic millimeters per hour conversion exact?
It's exact under the SI-based volume and time definitions used here, since both units convert to cubic meters per second through fixed, non-rounded factors.
Where is this conversion commonly used?
Flow rate conversions like this are used in plumbing, HVAC, irrigation, chemical processing, fuel and water metering, and engineering flow calculations.
Can I convert cubic millimeters per hour back to imperial gallons per day?

About this conversion
This page converts imperial gallons per day (imp gal/d) into cubic millimeters per hour (mm3/h), two units of volumetric flow rate.
The Imperial Gallon (imp gal) is a unit of volume. The Day (d) is a unit of time.
The Cubic Millimeter (mm3) is a unit of volume. The Hour (h) is a unit of time.
The formula is mm3/h = imp gal/d × 189420, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
