  • Freezing point of water is 0°C
  • Boiling point of water is 100°C
  • Human body temperature is 37°C
• Fahrenheit Scale


  • Used in the US
  • Freezing point of water is 32°F
  • Boiling point of water is 212°F

• Anders Celsius

• Gabriel Fahrenheit

• Kelvin


  The SI unit for temperature
• Converting Celsius (°C) to Fahrenheit (°F)


  F = (C x 9/5) + 32
• Converting 26°C to °F

  • F = (26 x 9/5) + 32 = 78.8°F
• Converting Fahrenheit (°F) to Celsius (°C)

  C = 5/9 (F - 32)
• Converting 59°F to °C

  • C = 5/9 (59 - 32) = 15°C
