About Converting Cubic Meter per Days to Gallon per Seconds
Cubic Meter 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 meter per days × 0.00305754690229
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per days equals 0.0000115740740741 base units, and 1 gallon per seconds equals 0.003785411784 base units, so dividing one by the other gives the direct cubic meter per days-to-gallon per seconds factor of 0.00305754690229.
Simple example
1 m3/d × 0.003057546902 = 0.0030575469 gal/s
1 cubic meter per days = 0.0030575469 gallon per seconds.
Real-world example
60 m3/d × 0.003057546902 = 0.1834528141 gal/s
60 cubic meter per days = 0.1834528141 gallon per seconds.

Frequently asked questions
How many gallon per seconds are in 1 cubic meter per days?
1 cubic meter per days equals 0.0030575469 gallon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per days to gallon per seconds?
Multiply the cubic meter per days value by 0.003057546902. The converter above does this instantly to whatever precision you set.
How do I convert gallon per seconds back to cubic meter per days?
Use the reverse factor: 1 gallon per seconds equals 327.0595781 cubic meter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per days?
Cubic Meter per Days (m3/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 meter per days to gallon per seconds conversion exact?
Yes. Both cubic meter per days and gallon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.003057546902 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.
