About Kelvin to Celsius Conversion

Kelvin (K) and Celsius (°C) are both units used to measure temperature, but they belong to different systems. The Kelvin scale is part of the absolute thermodynamic temperature scale used mainly in scientific and engineering contexts. Celsius, on the other hand, is commonly used in daily life, weather reports, and general temperature measurements.

The key difference between Kelvin and Celsius is the starting point. The Celsius scale sets 0°C as the freezing point of water and 100°C as the boiling point, while the Kelvin scale starts from absolute zero — the point where all molecular motion stops — which is 0 K or -273.15°C.

Kelvin to Celsius Formula

To convert Kelvin to Celsius, use this simple formula:

°C = K - 273.15

For example:

300 K = 300 - 273.15 = 26.85°C

Why Convert Kelvin to Celsius?

• 👩‍🔬 Scientific calculations and thermodynamic formulas often use Kelvin.
• 🌡️ Converting to Celsius makes results relatable to daily human experience.
• 📚 Many academic textbooks and labs report data in Celsius for interpretation.
• 🔬 Physics, chemistry, astronomy, and biology frequently switch between both scales.

Common Conversions

• 0 K = -273.15°C (Absolute Zero)
• 273.15 K = 0°C (Freezing point of water)
• 373.15 K = 100°C (Boiling point of water)
• 310.15 K = 37°C (Average human body temperature)

What is Kelvin?

The Kelvin scale was developed by Lord Kelvin in the 19th century. It is used in the International System of Units (SI) and is based on the thermodynamic absolute zero point. In scientific communities, Kelvin is essential for measurements involving physical laws and theories.

Unlike Celsius or Fahrenheit, Kelvin does not use the term "degree." Instead, temperatures are simply stated as "Kelvin," for example, "300 Kelvin."
