About Converting Milliliter per Days to Liter per Days
Milliliter per Days and Liter 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
liter per days = milliliter per days × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per days equals 1.157407e-11 base units, and 1 liter per days equals 1.157407e-8 base units, so dividing one by the other gives the direct milliliter per days-to-liter per days factor of 0.001.
Simple example
1 mL/d × 0.001 = 0.001 L/d
1 milliliter per days = 0.001 liter per days.
Real-world example
60 mL/d × 0.001 = 0.06 L/d
60 milliliter per days = 0.06 liter per days.
Conversion table
| Milliliter per Days (mL/d) | Liter per Days (L/d) |
|---|---|
| 0.1 mL/d | 0.0001 L/d |
| 1 mL/d | 0.001 L/d |
| 10 mL/d | 0.01 L/d |
| 60 mL/d | 0.06 L/d |
| 100 mL/d | 0.1 L/d |
| 1,000 mL/d | 1 L/d |
Reverse conversion: Liter per Days to Milliliter per Days
0.001 L/d × 1000 = 1 mL/d
0.001 liter per days = 1 milliliter per days.
milliliter per days = liter per days × 1000

Frequently asked questions
How many liter per days are in 1 milliliter per days?
1 milliliter per days equals 0.001 liter per days, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to liter per days?
Multiply the milliliter per days value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert liter per days back to milliliter per days?
Use the reverse factor: 1 liter per days equals 1,000 milliliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per days?
Milliliter per Days (mL/d) is a unit of flow rate.
What is a liter per days?
Liter per Days (L/d) is a unit of flow rate.
Is the milliliter per days to liter per days conversion exact?
Yes. Both milliliter per days and liter per days are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
