1. Measurement Units and Examples

Key Concepts & Definitions

  • Length : measures distance and uses millimetres (mm), centimetres (cm), metres (m), and kilometres (km).
  • Mass : uses milligrams (mg), grams (g), and kilograms (kg).
  • Capacity : measures how much a container can hold and uses millilitres (mL) and litres (L).

Essential Points

  • Time is measured in seconds, minutes, and hours.

  • Examples of measurements are:

    • 3 m for length
    • 2,5 kg for mass
    • 750 mL for capacity
    • 45 minutes for time

L-M-C-T: length, mass, capacity, time

2. Unit Conversion Rules

★ Must-know

📌 When converting from a big unit to a small unit, multiply; when converting from a small unit to a big unit, divide.

  • The length conversion relationships are:
    • 1 km = 1 000 m
    • 1 m = 100 cm
    • 1 cm = 10 mm

Further detail

  • The mass conversion relationships are 1 kg = 1 000 g and 1 g = 1 000 mg.

  • The capacity conversion relationship is 1 L = 1 000 mL.
