Measures

Bayani Gaba-gaba

Measures connect mathematics to the physical world. Every time you read a thermometer, time a race, estimate the height of a building or calculate how fast a car is travelling, you are applying the ideas in this topic. Fluency with scales, units and compound measures is essential across science, geography and everyday life.

You will learn to read scales accurately, convert between 12-hour and 24-hour time, estimate real-world quantities sensibly, measure and describe angles using three-figure bearings, and work with the compound measures speed, density and pressure using their defining formulae.

A nurse reads a thermometer graduated in half-degree intervals. A pilot reports a heading of 072 degrees to air-traffic control. An engineer calculates whether a bridge can withstand a pressure of 850 kPa. Behind each of these tasks lies the same skill: extracting a reliable number from a measuring instrument or formula and knowing what it means.
