The four main temperature scales are:

  1. Celsius (°C) - Used globally, based on water's freezing (0°) and boiling (100°) points
  2. Fahrenheit (°F) - Commonly used in the U.S., freezing point at 32°, boiling at 212°
  3. Kelvin (K) - The SI unit, starts at absolute zero (-273.15°C)
  4. Rankine (°R) - Absolute scale using Fahrenheit-sized degrees, primarily used in engineering
