About Converting Megaliter per Days to Cubic foot per Seconds
Megaliter per Days and Cubic foot 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
cubic foot per seconds = megaliter per days × 0.408734568536
This factor comes from each unit's defined relationship to the category's base unit: 1 megaliter per days equals 0.0115740740741 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct megaliter per days-to-cubic foot per seconds factor of 0.408734568536.
Simple example
1 ML/d × 0.4087345685 = 0.4087345685 ft3/s
1 megaliter per days = 0.4087345685 cubic foot per seconds.
Real-world example
60 ML/d × 0.4087345685 = 24.52407411 ft3/s
60 megaliter per days = 24.52407411 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 megaliter per days?
1 megaliter per days equals 0.4087345685 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert megaliter per days to cubic foot per seconds?
Multiply the megaliter per days value by 0.4087345685. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to megaliter per days?
Use the reverse factor: 1 cubic foot per seconds equals 2.446575546 megaliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a megaliter per days?
Megaliter per Days (ML/d) is a unit of flow rate.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
Is the megaliter per days to cubic foot per seconds conversion exact?
Yes. Both megaliter per days and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 0.4087345685 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.
