The document provides information on measurements and units of measurement. It includes: - Converting between different units like metres to kilometres - Calculating speeds, rates, volumes and surface areas using formulas - Measuring tools for different quantities like length, volume, mass - Examples of calculating speeds, volumes, areas of different shapes

2. Units of measurement Measuring unit Medium Distance Metre (m) Area Square metre (m 2 ) Volume Cubic metre (m 3 ) Volume Litre
