Litres To Milliliters – Definition with Examples

Phoebe Belza-Barrientos

Updated on January 6, 2026

Liters and milliliters are metric volume units used to measure liquid capacity. A liquid’s capacity is measured in milliliters, centiliters, liters, and kiloliters. While all of these units indicate the same quantity, their values differ. Today, we will explore how many ml in a liter and how we can use it in the real world. We will discuss how to measure liter to milliliters and provide you with practice problems and worksheets to help you learn more!

What is a liter?

The liter is the fundamental unit of measurement for liquid capacity and equals one cubic decimetre (1 liter = 1 dm3). The letter ‘l’ or L represents a liter.

What is a milliliter?

A milliliter is a small metric unit that represents liquid volume or capacity. It measures a smaller amount of liquid and is equivalent to 1000 milliliters (1 liter = 1000 milliliters). Milliliters are abbreviated ml. Now you know 1 liter equals how many milliliters, let’s explore further. 

According to SI terminology, the milliliter is based on the liter (US spelling), which is spelled “liter”. Originally part of the French metric system, the name “liter” was derived from the phrase “litron,” an early alternative to the French liter. Many tiny containers used in daily life are measured in milliliters, such as plastic bottles, cans, drinking glasses, juice and milk cartons, yogurt, toothpaste tubes, perfume/cologne bottles, etc. Measurement instruments such as graduated cylinders, beakers, pipettes, measurement cups, etc.

How to convert milliliters to liters?

When working with liquids, it’s often necessary to convert between liters (L) and milliliters (ml). Remember that 1 liter equals 1000 milliliters, so conversion is simple: just multiply the number of liters by 1000 to get milliliters.

As 1 liter equals 1000 ml, the conversion factor for converting liters to milliliters is 1000. 

• In order to convert liter to ml, multiply the quantity by 1000. For instance, if we convert 7 liters to ml. So, 7 × 1000 = 7000 ml. Therefore, 7 liters = 7000 ml.
• It is important to note, however, that when converting milliliters to liters, we multiply by 1000. For milliliter example, if we convert 9000 ml to L. So, 9000 ÷ 1000 = 9 liters. 

The table below will help you convert liter to milliliter

Tip: To convert milliliters back to liters, simply divide the number of milliliters by 1000.

How many liters in a milliliter?

A milliliter is equal to 0.001 liters, which means you divide the number of milliliters by 1000 to get liters. That the answer on the question how many ml are in a liter. Liters and milliliters are both metric units used to measure liquid volumes. Other metric liquid units include centiliters and kiloliters, each representing different scales of measurement. Although these units all measure volume, their numeric values differ. Converting between milliliters and liters is simple once you remember that 1000 milliliters make 1 liter.

How many ml are in a liter?

A liter is equal to 1000 milliliters, so multiplying L by 1000 (or equivalently moving the decimal point three places to the right) will convert 1L to ml. Liter to milliliters are metric volume units used to measure liquid volumes. There are four measurements of liquid capacity: milliliters, centiliters, liters, and kiloliters. Despite the fact that these units represent the same quantity, their values differ. After we figured out how many ml in L and vise versa let’s do some examples!
