Temperature
Conversion
Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder.
Temperature Scales Explained
- Celsius (°C): Also known as centigrade, it is the most widely used temperature scale. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure.
- Fahrenheit (°F): Used primarily in the United States. Water freezes at 32°F and boils at 212°F.
- Kelvin (K): The base unit of temperature in the SI system. Zero Kelvin (0 K) is absolute zero, the theoretical temperature at which all thermal motion ceases. Note that Kelvin does not use a degree symbol (°).
[!TIP]
Fun Fact: At -40 degrees, the Celsius and Fahrenheit scales meet. That means -40°C is exactly the same temperature as -40°F. It’s just extremely cold!
