Aotearoa New Zealand uses the metric system for its measurements, eg, weight and height. This is in keeping with the International System of Units (SI). This means that weight is measures in grams and kilograms and length is measured in millimetres, centimetres and metres.
Some countries still use the imperial units of measure where weight is measured in pounds and stones and length is measured in feet and inches.
