Kelvin to Celsius Converter

Kelvin

The Kelvin (K) is the SI unit of temperature used in scientific contexts to measure absolute temperature. It is named after the physicist William Thomson, Lord Kelvin. The Kelvin scale starts at absolute zero, the theoretical point where molecular motion ceases, and increments are equivalent to those on the Celsius scale. Kelvin is crucial in scientific research and engineering, particularly in fields like thermodynamics and quantum mechanics, where absolute temperature measurements are essential.

Celsius

A degree Celsius (°C) is a unit of temperature measurement in the metric system. It is used to quantify temperature based on the freezing point of water at 0°C and the boiling point at 100°C under standard atmospheric conditions. Celsius is widely used around the world for everyday temperature readings, weather forecasts, and scientific research. This scale is integral to the International System of Units (SI) and is commonly used in most countries, excluding the United States, where Fahrenheit is more prevalent.

How to convert Kelvin to Celsius?

To convert a temperature from Kelvin (K) to Celsius (°C), we use the formula:

Celsius = Kelvin − 273.15

Let's go through the conversion step by step for 20 K:

1. Start with the Kelvin temperature:
   Kelvin = 20
2. Subtract 273.15:
   20 − 273.15 = ؜-253.14999999999998
3. Final Result:
   20 K = ؜-253.14999999999998°C

Therefore, 20 Kelvin is equivalent to ؜-253.14999999999998 degrees Celsius.
