Celsius to Kelvin: Comprehensive Guide for Scientific Research and Academic Studies
Scientific Definition and Scale Relationship
Celsius (°C) is a metric temperature scale where 0° represents the freezing point and 100° represents the boiling point of water at standard atmospheric pressure (1 atm). Kelvin (K) is the SI base unit for temperature, starting from absolute zero (0 K = -273.15°C), where all molecular motion theoretically ceases. The conversion follows the exact linear relationship: K = °C + 273.15.
Historical Development and Scientific Significance
The Celsius scale was originally proposed by Swedish astronomer Anders Celsius in 1742, initially with 0° as boiling point and 100° as freezing point, later inverted to today's standard form. The Kelvin scale was introduced by Scottish physicist William Thomson, Lord Kelvin in 1848, based on the revolutionary concept of absolute zero - the theoretical temperature at which all molecular motion ceases, providing a fundamental reference point for scientific calculations.
