LAB 1 METRIC LENGTH REVIEW
  • ALL LENGTHS OR DISTANCES IN METRIC ARE BASED ON
    THE UNIT OF THE METRE
  • THE MOST COMMON PREFIXES CHANGE BY UNITS OF 1000

18
LAB 1 METRIC LENGTH REVIEW
  • EXAMPLES
  • 1 kilometre (1km) 1000 metres
  • 1 metre (1m) 1000 millimetres
  • 1 millimetre (1mm) 1000 micrometre
  • micrometre (1?m) 1000 nanometre (nm)

19
LAB 1 METRIC LENGTH REVIEW
  • The exception to the 1000 rule for distance
    conversions is cms
  • 1 metre is equal to 100 cm and 1 cm is equal to
    10 mm
  • 1 cm 10 mm

20
LAB 1 METRIC QUESTIONS
  • 2.6 mm is equal to
  • _______ cm
  • _______ ?m
  • _______ nm

21
LAB 1 METRIC QUESTIONS
  • 2.6 mm is equal to
  • 0.26 cm
  • 2600 ?m
  • 2600000 nm
