About Converting Liter per Days to Cubic Kilometer per Days
Liter per Days and Cubic Kilometer per Days 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 kilometer per days = liter per days × 1e-12
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 kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct liter per days-to-cubic kilometer per days factor of 1e-12.
Simple example
1 L/d × 1e-12 = 1e-12 km3/d
1 liter per days = 1e-12 cubic kilometer per days.
Real-world example
60 L/d × 1e-12 = 6e-11 km3/d
60 liter per days = 6e-11 cubic kilometer per days.

Reverse conversion: Cubic Kilometer per Days to Liter per Days
1e-12 km3/d × 1e+12 = 1 L/d
1e-12 cubic kilometer per days = 1 liter per days.
liter per days = cubic kilometer per days × 1e+12

Frequently asked questions
How many cubic kilometer per days are in 1 liter per days?
1 liter per days equals 1e-12 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert liter per days to cubic kilometer per days?
Multiply the liter per days value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to liter per days?
Use the reverse factor: 1 cubic kilometer per days equals 1e+12 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 kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the liter per days to cubic kilometer per days conversion exact?
Yes. Both liter per days and cubic kilometer per days are defined by fixed standards rather than physical artifacts, so the factor of 1e-12 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.
