1 mL = 0.001 L (milliliter → liter)
1 mL = 0.001 L
1 milliliter equals 0.001 liters. To convert milliliters to liters, multiply the milliliter value by 0.001. For quick reference: 1 mL = 0.001 L, 5 mL = 0.005 L, 10 mL = 0.01 L, 100 mL = 0.1 L.
Liters = Milliliters × 0.001Millilitres to litres divides by 1000. A 500 mL bottle is 0.5 L; a 330 mL can is 0.33 L. The conversion is a clean decimal shift and the two units cover different scales of the same metric system — millilitres for doses, recipes, and drinks; litres for bottles, tanks, and engine displacement. Keep millilitres for any recipe arithmetic, then express the total in litres only for a tidy final figure.
Pharmacists and lab technicians reach for this one when a formulation sheet is written in litres but a syringe or graduated cylinder only reads millilitres. A 500 mL IV bag is 0.5 L; a 1500 mL saline batch is 1.5 L; a 250 mL flask fill is 0.25 L. Because it's a plain decimal shift, the safest habit for dosing work is to keep three decimal places rather than rounding, since a dropped zero here means a tenfold dosing error.
Start with your value in milliliters.
Multiply the milliliter value by 0.001. This is the exact conversion factor from milliliters to liters.
The product is your value in liters. For example, 5 mL × 0.001 = 0.005 L.
The exact factor from milliliters to liters is 0.001.

A standard medicine dropper is 1 mL. A teaspoon holds 5 mL. A typical wine glass pour is 150 mL.
The milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter, or one cubic centimeter. It is the everyday unit for medication dosing, beverage sizes outside the US, and cooking in most of the world. Note that a US fluid ounce is 29.5735 mL, while a UK fluid ounce is 28.4131 mL.
The liter (L) is a metric unit of volume defined as exactly one cubic decimeter (1 dm³). Although not an SI base unit (the SI unit of volume is the cubic meter), it is the most common metric volume unit in everyday life, used for beverages, fuel, and chemistry. One liter of pure water at 4 °C weighs almost exactly one kilogram.
