What are some common temperature units used worldwide?
Two common temperature units are used internationally: Celsius (°C) and Kelvin (K).
Celsius is widely used in many countries as the standard unit for measuring temperature. It is based on the freezing point of water at 0°C and the boiling point at 100°C under normal atmospheric pressure. Celsius is used in scientific research, weather forecasts, and general temperature measurements in many parts of the world.
Kelvin is another commonly used temperature unit, primarily in scientific and technical fields. It is the base unit of temperature in the International System of Units (SI) and is used in physics, chemistry, and engineering. The Kelvin scale starts from absolute zero, which is the point at which all molecular motion stops. Absolute zero is defined as 0 Kelvin (0 K), which is equivalent to -273.15°C.
While Celsius and Kelvin are the most widespread temperature units used globally, Fahrenheit is also used in a few countries like the United States. However, its usage is relatively limited compared to Celsius and Kelvin.
