This activity is about converting **measurements into larger units.**

__Things we need to know:__

g = grams

kg = kilograms

km - kilometres

m = metres

cm = centimetres

There are** 1,000 grams in 1 kilogram.**

To convert grams to kilograms, **divide by 1,000**

There are **1,000 metres in a kilometre**.

To convert metres to kilometres, **divide by 1,000**

There are **100 centimetres in one metre.**

To convert centimetres to metres, **divide by 100 ** (watch out for this one - we divide by 100, not 1,000)

**Top Tips:**

When dividing by 100, each digit moves 2 places to the right.

When dividing by 1,000, each digit moves 3 places to the right.

Decimal points do not move!

Let's have a go:

Convert 600 cm to m

We know that there are 100 cm in 1 m so we need to **divide 600 by 100**

**600 ÷ 100 = 6 m** (we must remember to add the correct unit of measure)

Here's another example:

5,500 m = _________ km

To convert metres to kilometres, we need to **divide by 1,000**

When we divide 5,500 by 1,000 we move 3 places to the right.

**Remember to add a decimal point.** (Imagine that there is a decimal point at the end of the number 4,500 - we don't show it if there isn't a digit after it! )

5,500 ÷ 1,000 = 5.5 **(not 55)**

Are you ready to give this a go?
