About Converting Liter per Days to Cubic foot per Seconds
Liter 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 = liter per days × 4.087346e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per days equals 1.157407e-8 base units, and 1 cubic foot per seconds equals 0.028316846592 base units, so dividing one by the other gives the direct liter per days-to-cubic foot per seconds factor of 4.087346e-7.
Simple example
1 L/d × 4.087346e-7 = 4.087346e-7 ft3/s
1 liter per days = 4.087346e-7 cubic foot per seconds.
Real-world example
60 L/d × 4.087346e-7 = 0.0000245241 ft3/s
60 liter per days = 0.0000245241 cubic foot per seconds.

Frequently asked questions
How many cubic foot per seconds are in 1 liter per days?
1 liter per days equals 4.087346e-7 cubic foot per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert liter per days to cubic foot per seconds?
Multiply the liter per days value by 4.087346e-7. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per seconds back to liter per days?
Use the reverse factor: 1 cubic foot per seconds equals 2,446,575.546 liter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per days?
Liter per Days (L/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 liter per days to cubic foot per seconds conversion exact?
Yes. Both liter per days and cubic foot per seconds are defined by fixed standards rather than physical artifacts, so the factor of 4.087346e-7 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.
