NZ Level 4 Mixed Unit Conversions
Lesson We've learned about volume and capacity. Even though they are very closely linked, they are slightly different.

• Volume is the amount of space a 3D object takes up.
• Capacity is the amount a container can hold.

Handy Conversions
 Volume Capacity $1$1 cm3 $=$= $1$1 mL $1000$1000 cm3 $=$= $1$1 L $1$1 m3 $=$= $1000$1000 L $1$1 m3 $=$= $1$1 kL

When you're converting between volume and capacity, just think which unit of measurement there will be more of to work out whether you need to multiply or divide. For example,

• if I'm converting from cubic centimetres to litres, I will need to divide because there are $1000$1000 cm3 in $1$1 L.
• if I'm converting from cubic metres to litres, I will need to multiply because there are $1$1 m3 is equivalent to $1000$1000 L.

• if I'm converting from kilolitres to cubic metres, I don't need to change anything! That's because $1$1 kL is equivalent to $1$1 m3.

#### Worked Examples
