How many litres are in a millilitre?
One millilitre is 0.001 litres. To convert any amount, multiply by 0.001. Going the other way, one litre is 1000 millilitres.
What is the formula to convert mL to L?
Multiply the millilitre figure by 0.001. So L = mL × 0.001. For a quick mental estimate, dividing by about 1000 gets you close enough for most everyday purposes.
What does a millilitre actually look like?
One millilitre is a fifth of a teaspoon. A millilitre is exactly one cubic centimetre, which is why medical equipment marked cc and mL means the same thing.
And what is a litre?
One litre is a large bottle of soft drink. The litre is exactly one cubic decimetre. It is not strictly an SI unit but is accepted for use with SI, and it is the fuel and beverage unit almost everywhere.
Is this conversion exact?
Yes. Since the 1959 international yard and pound agreement, the imperial and metric systems are related by exact definitions rather than measurements — the inch is exactly 25.4 mm and the pound exactly 0.45359237 kg. Everything derived from those, including this conversion, is therefore exact. Round at the end rather than partway through, since rounding mL before converting introduces an error the conversion then multiplies.

L = mL × 0.001
Worked example
10 mL = 0.01 L. For a sense of scale, one millilitre is a fifth of a teaspoon, and one litre is a large bottle of soft drink.

Getting it right
Check whether your source means US or imperial measures. An imperial gallon is about 20% larger than a US gallon, and an imperial fluid ounce is slightly smaller than a US one. Recipes and fuel-economy figures are where this bites hardest, because the numbers look plausible either way.
