What to Focus On

  • Unit = Internationally accepted reference standard
  • Measurement result = Number + Unit
  • Base quantities: Length, Mass, Time, Electric current, Temperature, Amount of substance, Luminous intensity

  • SI established in 1971 for global uniformity
  • Seven base units: m, kg, s, A, K, mol, cd
  • Two supplementary units: rad (plane angle), sr (solid angle)

  • More significant figures = Higher precision
  • Non-zero digits are always significant
  • Zeros between non-zeros are significant

Common Mistakes to Avoid

Significant figures are only important in final answers, not during intermediate calculations

Dimensional analysis can determine the complete formula including numerical constants

All zeros in a number are significant figures
