  • Metric units and imperial conversions
    11 = 1000ml
  • To convert between two units of measure
    Know the relationship between the two units
  • Measuring systems
    • Metric system
    • Imperial system
  • Metric system
    • Based on the number 10
    • Most commonly used system
    • Forms the basis of the Système Internationale d'Unitès (SI)
    • Examples: metres, grams, litres
  • Imperial system
    • Older
    • Still used in some countries such as the United States of America
    • Examples: miles, pounds, pints
  • Converting between measuring units
    1. Write the conversion equation with '1' on the left hand side: 1 (unit A)=(conversion factor)(unit B)
    2. When converting from left to right (from unit A to unit B), multiply by the conversion factor
    3. When converting from right to left (from unit B to unit A), divide by the conversion factor
  • Metric unit conversions
    • Area: 1 cm² = 100 mm²
    • Mass: 1 g = 1000 mg, 1 kg = 1000 g
    • Length: 1 cm = 10 mm, 1 m = 100 cm, 1 km = 1000 m
    • Volume and capacity: 1 cm³ = 1000 mm³, 1 ml = 1000 ml, 1 ha = 10 000 m², 1 km² = 1 000 000 m²
  • Imperial unit conversions
    • Length: 1 foot = 12 inches, 1 yard = 3 feet, 1 mile = 1760 yards
    • Area: 1 foot² = 144 inch², 1 yard² = 9 feet², 1 acre = 4840 yards²
    • Volume and capacity: 1 foot³ = 1728 inch³, 1 gallon = 8 pints, 1 pint = 20 fluid ounces
    • Mass: 1 pound = 16 ounces, 1 stone = 14 pounds
  • Converting between metric and imperial units
    1. Length: 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 yard = 0.9144 m, 1 mile = 1.6093 km
    2. Area: 1 acre = 0.4047 hectare (ha)

    4. Mass: 1 ounce = 28.3495 g, 1 pound (lb) = 0.4536 kg
  • Conversion factor
    A multiplier (or divider) that can be used to change a measure from one unit into its equivalent measure in another unit
  • Metric System
    A system of measurement based on the number 10, most commonly used, and forms the basis of the Système Internationale d'Unitès (SI)
  • Basis of System
    The system is built around multiples of 10: 10, 100, 1000, and so on
