What are Metric Units of Capacity?

Hello, Year 5! Today, we are going to learn about metric units of capacity. Capacity tells us how much liquid a container can hold. In the metric system, we have a few key units to measure capacity:

  • Millilitres (ml): This is a small unit. For example, a teaspoon can hold about 5 ml of liquid.
  • Litres (l): This is a larger unit. A big bottle of water usually holds 1 litre.

Comparing Millilitres and Litres

1 litre is equal to 1,000 millilitres. That means:

  • 1 l = 1,000 ml

Examples of Capacity

Here are some examples to help you understand:

  • A small juice box might hold 200 ml.
  • A standard bottle of soda is usually 2 l.
  • A swimming pool can hold thousands of litres of water!

Key Rules for Measuring Capacity

  • To convert litres to millilitres, multiply by 1,000.
    • For example: 3 l = 3 × 1,000 = 3,000 ml
  • To convert millilitres to litres, divide by 1,000.
    • For example: 500 ml = 500 ÷ 1,000 = 0.5 l

Tips and Tricks

  • Visualisation: Picture a 1-litre bottle. It helps you understand how much 1 litre is!
  • Use everyday items: Look at drink containers in your fridge. Check how many millilitres or litres they hold.
  • Practice conversions: Try converting between ml and l using simple numbers.
