Enter any temperature value in Kelvin (must be 0 or greater)

Quick Reference:

  • Absolute zero is 0K (-273.15°C)
  • Water freezes at 273.15K (0°C)
  • Room temperature is about 293-298K (20-25°C)
  • Body temperature is 310.15K (37°C)
  • Water boils at 373.15K (100°C)

The Kelvin to Celsius Converter is a simple tool that allows users to convert temperatures from Kelvin (K) to Celsius (°C). The Kelvin scale is widely used in scientific applications, while Celsius is commonly used in everyday weather reports and temperature measurements.

Understanding the Kelvin and Celsius Scales

The Kelvin scale is an absolute temperature scale used in physics and engineering. It starts at absolute zero (0 K), the theoretical lowest possible temperature. The Celsius scale, on the other hand, is based on the freezing and boiling points of water, making it more familiar for everyday temperature readings.

Kelvin to Celsius Conversion Formula

Converting Kelvin to Celsius is straightforward. The formula is:

$$ \text{Celsius} (°C) = \text{Kelvin} (K) - 273.15 $$

This means that to get a temperature in Celsius, you simply subtract 273.15 from the Kelvin value.

How to Use the Kelvin to Celsius Converter

  • Enter the temperature in Kelvin into the input field.
  • Click the “Convert” button to see the result in Celsius.
  • The result will be displayed instantly along with a temperature description.
  • Use the “Reset” button to clear the input and start over.

Examples of Kelvin to Celsius Conversion

Here are some common temperature conversions:

Kelvin (K) Celsius (°C)
0 K -273.15°C (Absolute Zero)
273.15 K 0°C (Freezing Point of Water)
310.15 K 37°C (Normal Human Body Temperature)
373.15 K 100°C (Boiling Point of Water)

Why Convert Kelvin to Celsius?

There are several reasons to convert Kelvin to Celsius:

  • Scientific Research: Many scientific equations and experiments require Kelvin measurements, but results may need to be expressed in Celsius for clarity.
  • Weather and Climate: Weather reports commonly use Celsius, while scientific climate studies often use Kelvin.
  • Engineering Applications: Engineers may work with Kelvin in thermodynamic calculations but convert to Celsius for practical use.

Key Takeaways

  • The Kelvin scale starts at absolute zero (0 K), while the Celsius scale is based on water’s freezing and boiling points.
  • The formula for conversion is simple: K - 273.15 = °C.
  • Our Kelvin to Celsius Converter makes the process quick and easy.
