Convert Litre to Millilitre
1 litre = 1,000 millilitre (mL). For example, 10 litre = 10,000 millilitre and 100 litre = 100,000 millilitre. Type any value below to convert litre to millilitre both ways — it runs entirely in your browser.
Quick answer: Litre to Millilitre
1 Litre = 1,000 Millilitre (L → mL). To convert litre to millilitre, multiply by 1,000. To convert millilitre to litre, multiply by 0.001. The converter at the top does this instantly and both ways; the sections below give the formula, worked examples, a full conversion chart and answers to the most common litre-to-millilitre questions.
How to convert Litre to Millilitre
To convert litre to millilitre, multiply the number of litre by the conversion factor 1,000, because 1 L = 1,000 mL. The conversion is linear, so the same factor works for any value — whole numbers, decimals or fractions. For the reverse direction, 1 mL = 0.001 L, so you divide by 1,000 (or multiply by 0.001) to turn millilitre back into litre.
mL = L × 1,000 ·
L = mL × 0.001
- Write down the value you want to convert, in litre.
- Multiply it by 1,000.
- The result is the same area/length/quantity expressed in millilitre.

Litre vs Millilitre: which is bigger?
A litre is the larger unit: one litre equals 1,000 millilitres. Put another way, you need 1,000 millilitres to make a single litre.
What is a Litre? History, origin and usage
The litre was introduced in France in 1795 as a republican measure equal to one cubic decimetre, its name derived from the older French litron, in turn from Byzantine Greek (where it had been a unit of weight) via Late Medieval Latin. In 1901 the litre was redefined as the volume of one kilogram of pure water at maximum density, making it very slightly larger than a cubic decimetre. In 1964 that awkward definition was abandoned and the litre returned to being exactly one cubic decimetre.
The litre is the everyday metric unit of volume across most of the world: fuel sold at the pump, bottled water and soft drinks, milk, engine and cooking oil, and car engine capacity. It is the unit people reach for whenever a volume is larger than a kitchen spoonful but smaller than a tankful.
The litre is not an official SI unit but is accepted for use alongside it. Its symbol may be written as a capital L precisely because a lowercase l is easily mistaken for the digit 1 in many fonts.
What is a Millilitre? History, origin and usage
The millilitre is the litre scaled by the metric prefix milli- (Latin mille, a thousandth), so it inherits the litre's origin in the 1795 French metric reforms. Because the litre was defined in relation to the metre, the millilitre became exactly one cubic centimetre when the litre was tied to the cubic decimetre. It has been part of the coherent metric vocabulary ever since the SI prefixes were standardised.
The millilitre is the workhorse small-volume unit almost everywhere outside the United States: medicine doses, syringes and IV bags, drink and food nutrition labels, perfume and cosmetics, and home cooking. Laboratories and pharmacies use it constantly for measuring liquids. In medicine the equivalent term cubic centimetre (cc) is still heard, especially for syringes.
One millilitre is identical in volume to one cubic centimetre, because a litre is exactly one cubic decimetre. A standard metric teaspoon is taken as five millilitres, which is why liquid-medicine dosing cups are graduated in millilitres rather than spoons.

Tips for converting Litre to Millilitre
- To go from litre to millilitre, multiply by 1,000; to go back, divide by 1,000 (or multiply by 0.001).
- For a quick mental estimate, remember that 1 litre ≈ 1,000 millilitre, so 10 litre ≈ 10,000 millilitre.
- The converter above keeps full precision; the tables round for readability, so use the tool for exact figures.
- Both fields update live as you type — change either side to convert in that direction.
How to use this Litre to Millilitre converter
Type a number into the Litre field and the equivalent in Millilitre appears instantly — there is no “convert” button to press and nothing is sent to a server, so it works offline once the page has loaded and is safe for any data. You can also type into the Millilitre field to convert the other way (millilitre to litre). Use the swap control to flip the two units, and copy the result with a single click. Because the calculation runs in your browser with full floating-point precision, the converter is more exact than the rounded figures shown in the reference chart above — use the chart for quick look-ups and the tool for precise work.
Accuracy and method
Every figure on this page — the formula, the worked examples, the conversion chart and the “convert to other units” tables — is computed from a single verified conversion factor (1 L = 1,000 mL), never copied from a hand-typed lookup table that could drift. That factor is derived from each unit’s definition in terms of a common base unit, and an automated check re-verifies all of the site’s factors on every update, so the numbers here stay correct over time. This matters for litre-to-millilitre conversions because a small rounding error in a published table compounds quickly at larger quantities; computing from the exact factor avoids that.
Sources
- BIPM — The International System of Units (SI Brochure) — the defining document for the SI, published by the International Bureau of Weights and Measures. It fixes the base unit that this conversion resolves to, which is why the factor here can be exact rather than approximate.
- NIST — Definitions of the SI base units — the US National Institute of Standards and Technology reference for the SI base units, used here as an independent cross-check on the base-unit definition.
Watch the system: a <strong>US</strong> gallon, quart, pint and fluid ounce are <strong>not</strong> the same size as the <strong>imperial (UK)</strong> ones — a US gallon is 3.785 L while an imperial gallon is 4.546 L, and a US fluid ounce (29.57 mL) is slightly larger than an imperial fluid ounce (28.41 mL). The units on this page are labelled US or Imperial so the result is unambiguous.
Frequently asked questions
- How many millilitre are in 1 litre?
- 1 litre = 1,000 millilitre (mL). To convert any number of litre to millilitre, multiply by 1,000.
- How do I convert litre to millilitre?
- Multiply the number of litre by 1,000. For example, 10 litre = 10 × 1,000 = 10,000 millilitre, and 25 litre = 25,000 millilitre.
- How many litre are in 1 millilitre?
- 1 millilitre = 0.001 litre. So to convert millilitre back to litre, multiply by 0.001.
- What is the formula to convert litre to millilitre?
- millilitre = litre × 1,000. The reverse formula is litre = millilitre × 0.001.
- How much is 100 litre in millilitre?
- 100 litre = 100,000 millilitre. (And 1000 litre = 1,000,000 millilitre.)
- Which is bigger, a litre or a millilitre?
- A litre is larger: 1 litre = 1,000 millilitre.
- Is this litre to millilitre converter accurate?
- Yes — every value is computed from the exact 1,000 mL per L factor (not rounded look-up tables), and the factors are re-verified automatically on every update.
- Can I convert millilitre to litre too?
- Yes. The converter works both ways — enter a value in either field. 1 millilitre = 0.001 litre.
