Skin-Deep Look at Human Scales

Human beings like to measure things...by assigning numbers, we gain a sense of order and mastery. Some of the scales reflect inherent mathematical relationships (e.g. logarthmic or exponential), while other scales seem nominal by design.

Can you identify the following scales:

  • Saffir-Simpson Scale (5 levels)
  • Udden-Wentworth Scale (6 levels)
  • Glasgow Coma Score (15 levels)
  • Mohs Hardness Scale (10 levels)
  • Torino Impact Hazard Scale (10 levels)
  • Lab Biosafety Levels (4 levels)
  • Fujita Scale (7 levels)
  • Richter Scale (10 levels)
  • Stanford-Binet Scale (8 levels)
  • Diatonic Scale (7+ levels)
  • pH Scale (15 levels)
  • Specific Gravity Scale (22 levels)
