Milliliters to Liters formula
Converting milliliters to liters is a single multiplication by 0.001.
L = mL × 0.001
Put another way, one milliliter is exactly 1/1,000 of a liter.
Why this factor: the milliliter and the liter are both defined against the liter, so dividing one definition by the other gives 0.001 directly. Both definitions are set out in full below.
To go the other way, divide by 0.001 — or use the Liters to Milliliters converter, which is the same calculation reversed.
Worked example
Take 2 mL and multiply by the factor 0.001: the result is 0.002 L.
2 mL × 0.001 = 0.002 L
The converter above does this for any value you type, in either direction.
