About Converting Cubic yard per Days to Gallon per Seconds
Cubic yard per Days and 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
gallon per seconds = cubic yard per days × 0.00233766233766
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 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic yard per days-to-gallon per seconds factor of 0.00233766233766.
Simple example
1 yd3/d × 0.002337662338 = 0.0023376623 gal/s
1 cubic yard per days = 0.0023376623 gallon per seconds.
Real-world example
60 yd3/d × 0.002337662338 = 0.1402597403 gal/s
60 cubic yard per days = 0.1402597403 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic yard per days?
1 cubic yard per days equals 0.0023376623 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per days to gallon per seconds?
Multiply the cubic yard per days value by 0.002337662338. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic yard per days?
Use the reverse factor: 1 gallon per seconds equals 427.7777778 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 gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
Is the cubic yard per days to gallon per seconds conversion exact?
Yes. Both cubic yard per days and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.002337662338 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.
