About Converting Cubic yard per Days to Imperial gallon per Seconds
Cubic yard per Days and Imperial gallon 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
imperial gallon per seconds = cubic yard per days × 0.00194651108095
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per days equals 0.00000884901456 base units, and 1 imperial gallon per seconds equals 0.00454609 base units, so dividing one by the other gives the direct cubic yard per days-to-imperial gallon per seconds factor of 0.00194651108095.
Simple example
1 yd3/d × 0.001946511081 = 0.0019465111 imp gal/s
1 cubic yard per days = 0.0019465111 imperial gallon per seconds.
Real-world example
60 yd3/d × 0.001946511081 = 0.1167906649 imp gal/s
60 cubic yard per days = 0.1167906649 imperial gallon per seconds.

Frequently asked questions
How many imperial gallon per seconds are in 1 cubic yard per days?
1 cubic yard per days equals 0.0019465111 imperial gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per days to imperial gallon per seconds?
Multiply the cubic yard per days value by 0.001946511081. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per seconds back to cubic yard per days?
Use the reverse factor: 1 imperial gallon per seconds equals 513.7396904 cubic yard per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per days?
Cubic yard per Days (yd3/d) is a unit of flow rate.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
Is the cubic yard per days to imperial gallon per seconds conversion exact?
Yes. Both cubic yard per days and imperial gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.001946511081 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.
