We've learned about volume and capacity. Even though they are very closely linked, they are slightly different.
Volume | Capacity | |
$1$1 cm^{3} | $=$= | $1$1 mL |
$1000$1000 cm^{3} | $=$= | $1$1 L |
$1$1 m^{3} | $=$= | $1000$1000 L |
$1$1 m^{3} | $=$= | $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 metres to litres, I will need to multiply because there are $1$1 m^{3} 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 m^{3}.
Convert $6750$6750 cubic centimetres (cm^{3}) to litres (L).
Convert $8100$8100 litres (L) to cubic metres (m^{3}).
Use appropriate scales, devices, and metric units for length, area, volume and capacity, weight (mass), temperature, angle, and time
