Celsius (°C)
Definition: Celsius (°C) is a temperature scale in which water freezes at 0°C and boils at 100°C under standard atmospheric conditions. It is used worldwide in scientific and everyday contexts.
History: The Celsius scale was developed in 1742 by Anders Celsius, with the original scale using the freezing point of water at 0°C and boiling at 100°C. It was later reversed to the current standard. The scale became the standard in scientific use by 1967, based on the Kelvin scale.
Current Use: Celsius is widely used for weather, cooking, and in scientific applications, especially in countries using the metric system. It is the standard temperature scale in most countries.
Kelvin (K)
Definition: Kelvin (K) is the SI base unit of temperature, starting from absolute zero (0 K) where molecular motion stops. It is used in scientific and engineering fields.
History: The Kelvin scale was introduced by William Thomson (Lord Kelvin) in 1848, using absolute zero as the zero point and based on Celsius increments. It revolutionized thermodynamics and became the standard for scientific temperature measurements.
Current Use: Kelvin is essential in scientific research, particularly in physics, thermodynamics, and chemistry. It is used to express temperatures in absolute terms, crucial for understanding molecular behavior and energy systems.
