About Converting Imperial gallon per Seconds to Cubic Meter per Days
Imperial gallon per Seconds and Cubic Meter per Days 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
cubic meter per days = imperial gallon per seconds × 392.782176
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 cubic meter per days equals 0.0000115740740741 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-cubic meter per days factor of 392.782176.
Simple example
1 imp gal/s × 392.782176 = 392.782176 m3/d
1 imperial gallon per seconds = 392.782176 cubic meter per days.
Real-world example
60 imp gal/s × 392.782176 = 23,566.93056 m3/d
60 imperial gallon per seconds = 23,566.93056 cubic meter per days.

Frequently asked questions
How many cubic meter per days are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 392.782176 cubic meter per days, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to cubic meter per days?
Multiply the imperial gallon per seconds value by 392.782176. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per days back to imperial gallon per seconds?
Use the reverse factor: 1 cubic meter per days equals 0.0025459404 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
What is a cubic meter per days?
Cubic Meter per Days (m3/d) is a unit of flow rate.
Is the imperial gallon per seconds to cubic meter per days conversion exact?
Yes. Both imperial gallon per seconds and cubic meter per days are defined by fixed standards rather than physical artifacts, so the factor of 392.782176 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.
