An introduction to the measurement of weight in kilograms and height in centimetres, with a demonstration of how to read scales. At the South Pole, Dave needs to read the scales to weigh the penguins. The scales are marked in tens. To make reading the scales easier and more effective he adds up in fives. Next, the height of the penguins are measured in centimetres. This scale is also marked in tens.
