Units and Equations

• Mass can be measured in kg or g

  • g to kg = / 1000
  • kg to g = x 1000
• Length can have lots of units, including mm, cm, m and μm

  • mm to μm - x1000
  • μm to mm - /1000
  • μm to nm - x1000
  • nm to μm - /1000
  • μm to cm - /10,000
  • cm to μm - x10,000
• Time can be measured in minutes and seconds.

  • Min to S - x60
  • S to min - /60
• Volume can be measured in m^3, dm^3 and cm^3

  • m to dm - x1000
  • dm to m - /1000
  • dm to cm - x1000
  • cm to dm - /1000
• magnification - image/actual
• light intensity - 1/d^2
