1. Celsius (°C):
Celsius temperature scale is also called centigrade temperature scale. The degree Celsius (°C) bases on 0 for the freezing point of water and 100 for the boiling point of water.
2. Fahrenheit (°F):
Fahrenheit temperature scale (°F) bases on 32 for the freezing point of water and 212 for the boiling point of water.
3. Kelvin (K):
According to Kelvin temperature scale, the temperature of absolute zero occurs at 0K = -273.15°C (or −459.67 °F), and the freezing point of water at sea-level atmospheric pressure occurs at 273.15K = 0°C.
