About Converting Imperial gallon per Days to Metric cup per Seconds
Imperial gallon per Days and Metric cup per Seconds 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
metric cup per seconds = imperial gallon per days × 0.00021046712963
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per days equals 5.261678e-8 base units, and 1 metric cup per seconds equals 0.00025 base units, so dividing one by the other gives the direct imperial gallon per days-to-metric cup per seconds factor of 0.00021046712963.
Simple example
1 imp gal/d × 0.0002104671296 = 0.0002104671 metric cup/s
1 imperial gallon per days = 0.0002104671 metric cup per seconds.
Real-world example
60 imp gal/d × 0.0002104671296 = 0.0126280278 metric cup/s
60 imperial gallon per days = 0.0126280278 metric cup per seconds.

Frequently asked questions
How many metric cup per seconds are in 1 imperial gallon per days?
1 imperial gallon per days equals 0.0002104671 metric cup per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per days to metric cup per seconds?
Multiply the imperial gallon per days value by 0.0002104671296. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per seconds back to imperial gallon per days?
Use the reverse factor: 1 metric cup per seconds equals 4,751.335763 imperial gallon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per days?
Imperial gallon per Days (imp gal/d) is a unit of flow rate.
What is a metric cup per seconds?
Metric cup per Seconds (metric cup/s) is a unit of flow rate.
Is the imperial gallon per days to metric cup per seconds conversion exact?
Yes. Both imperial gallon per days and metric cup per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.0002104671296 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.
