Milk is a staple food item in many households, and it comes in a variety of sizes and packaging options. Small cartons of milk are a convenient way to purchase milk in smaller quantities, and they are ideal for single-person households or for those who do not consume milk frequently.

But how many milliliters are in a small carton of milk? And what are the different sizes of small cartons of milk available? This definitive guide will answer all your questions about the milliliters in small cartons of milk, helping you make informed decisions when purchasing this essential beverage.

Small Carton of Milk: Milliliter Measurements Explained

The milliliter (mL) is the metric unit of volume, and it is the most common unit used to measure the volume of liquids. Small cartons of milk typically range in size from 125 mL to 250 mL, although some brands may offer larger or smaller sizes.

The most common size of a small carton of milk is 180 mL. This size is convenient for single-serving use, and it is often found in school lunch boxes or at convenience stores. Larger sizes, such as 250 mL cartons, are better suited for households with multiple milk drinkers or for those who use milk in cooking.

Types of Small Milk Cartons

There are two main types of small milk cartons: gable-top cartons and rectangular cartons. Gable-top cartons have a pointed top that can be folded down to create a spout for pouring. Rectangular cartons have a flat top that can be cut open with scissors.

Gable-top cartons are more common in the United States and Canada, while rectangular cartons are more common in Europe and Asia. Both types of cartons are made of paperboard, which is a strong and recyclable material.

Nutritional Value of Milk

Milk is an excellent source of essential nutrients, including protein, calcium, and vitamin D. A single 180 mL serving of milk provides approximately:

  • 8 grams of protein
  • 276 milligrams of calcium
  • 100 IU of vitamin D

Milk is also a good source of riboflavin, vitamin B12, and potassium.

Storage and Handling of Small Milk Cartons

Small cartons of milk should be stored in the refrigerator at a temperature of 40°F (4°C) or below. Once opened, milk should be consumed within 7-10 days.

Environmental Impact of Milk Cartons

Milk cartons are made from paperboard, which is a recyclable material. However, the plastic coating on the inside of the carton can make it difficult to recycle. Some communities have special recycling programs for milk cartons, so it is important to check with your local waste management authority to see if recycling is an option in your area.

Alternatives to Small Milk Cartons

If you are looking for an alternative to small milk cartons, there are several options available:

  • Glass bottles: Glass bottles are reusable and recyclable, and they do not contain any harmful chemicals. However, they are heavier and more fragile than cartons.
  • Plastic jugs: Plastic jugs are lightweight and durable, but they are not recyclable in all communities. They can also leach harmful chemicals into the milk over time.
  • Powdered milk: Powdered milk is a shelf-stable alternative to fresh milk. It is available in cans or bags, and it can be reconstituted with water when needed.


Small cartons of milk are a convenient and affordable way to purchase milk in smaller quantities. They come in a variety of sizes, from 125 mL to 250 mL, and they are typically made from recyclable paperboard.
