Understanding Metric vs Imperial Measurements

Metric System (Australia's Standard)

The metric system is Australia's official measurement system, used in science, industry, and daily life.

Common Metric Units:

  • Millimetre (mm): 1/1000 of a metre - used for small precise measurements
  • Centimetre (cm): 1/100 of a metre - common for everyday measurements
  • Metre (m): Base unit of length - room dimensions, height
  • Kilometre (km): 1000 metres - distances between cities

Benefits: Easy to convert (base 10), universally accepted, scientifically precise

Imperial System (Traditional)

The imperial system is still used in some countries and specific industries, making conversions essential.

Common Imperial Units:

  • Inch (in): 1/12 of a foot - small measurements, screen sizes
  • Foot (ft): 12 inches - human height, room dimensions
  • Yard (yd): 3 feet - fabric, sports fields
  • Mile (mi): 5,280 feet - long distances

Usage: Aviation, some construction, international trade
