Celsius (°C): The Celsius scale is one of the most widely used temperature scales in the world. In it, the freezing point of water is defined as 0 degrees Celsius (°C) and the boiling point of water is defined as 100 degrees Celsius (°C), both measured at normal atmospheric pressure at sea level. This scale is widely used in many countries to measure temperatures in everyday life, in domestic environments, in science and in many industries.
Fahrenheit (°F): The Fahrenheit scale is common in the United States and some other countries, although it is less used internationally. On this scale, the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point is 212 degrees Fahrenheit (°F), again, both measured at normal atmospheric pressure at sea level. The difference between Celsius and Fahrenheit is that values on the Fahrenheit scale are higher than the Celsius scale for the same temperature.
Kelvin (K): The Kelvin scale is an absolute temperature scale used primarily in science, especially physics and chemistry. Unlike the Celsius and Fahrenheit scales, Kelvin does not have negative values, since its zero point is known as "absolute zero", the lowest possible temperature, where molecules have no thermal movement. On the Kelvin scale, the freezing point of water is 273.15 Kelvin (K) and the boiling point is 373.15 Kelvin (K), both measured at normal atmospheric pressure at sea level.
These three temperature scales are widely used in different contexts and it is important to be aware of how to convert values between them if needed for international communication or to understand information in different measurement systems. Converting between Celsius and Kelvin is relatively straightforward (just add or subtract 273.15), but converting between Celsius and Fahrenheit requires a more complex formula.
