Understanding the Celsius Scale

The Celsius scale defines 0°C as the freezing point of water and 100°C as the boiling point under standard atmospheric pressure. It is widely used for everyday and scientific measurements worldwide.

History of the Celsius Scale

Developed by Anders Celsius in 1742 with an inverted scale, it was reversed in 1743. Renamed from centigrade to Celsius in 1948, it aligns closely with the Kelvin scale for absolute measurements.

Understanding the Kelvin Scale

The Kelvin scale is an absolute thermodynamic temperature scale where zero represents the theoretical absence of all thermal energy, known as absolute zero. It is the base unit of temperature in the International System of Units (SI).

History of the Kelvin Scale

Proposed by William Thomson (Lord Kelvin) in 1848, the scale was refined in 1854 with James Joule. It was formally adopted in 1954, defining the triple point of water at 273.16 K. In 2019, it was redefined using the Boltzmann constant for greater precision.

The Conversion Formula Explained

The formula to convert Celsius to Kelvin is:

Where \( K \) is the temperature in Kelvin and \( C \) is in Celsius. This addition accounts for the offset between the relative Celsius scale and the absolute Kelvin scale.

Step-by-Step Calculation Example

For 25°C: Add 273.15 to get 298.15 K.

Comparison of Temperature Scales

Celsius is relative and common in daily life, while Kelvin is absolute and used in scientific contexts. The scales differ by a fixed offset of 273.15 degrees.

FAQ

What is the formula for Celsius to Kelvin? The formula is K = C + 273.15.

Why is Kelvin used in science? Kelvin is an absolute scale starting from zero thermal energy, making it ideal for thermodynamic equations and avoiding negative values.

Is there a quick way to estimate conversions? Add 273 to Celsius for an approximate Kelvin value, adjusting by 0.15 for precision.

What is the difference between Celsius and Kelvin intervals? The degree intervals are identical; only the zero point differs by 273.15.

Can temperatures be negative in Kelvin? No, Kelvin starts at absolute zero (0 K), so negative values are not possible.
