Enter any temperature value in Celsius

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)
  • Water boils at 373.15K (100°C)

Converting Celsius to Kelvin is simple, but using a reliable converter makes it even easier. Whether you're a student, scientist, or anyone needing quick temperature conversions, our Celsius to Kelvin Converter ensures accuracy and convenience.

How the Converter Works

The Celsius to Kelvin conversion follows a straightforward mathematical formula. Since the Kelvin scale is an absolute temperature scale, it starts from absolute zero, making it widely used in scientific applications.

$$ K = C + 273.15 $$

Where:

  • K = Temperature in Kelvin
  • C = Temperature in Celsius

By adding 273.15 to a Celsius temperature, you obtain the equivalent temperature in Kelvin.

Steps to Use the Celsius to Kelvin Converter

Frequently Asked Questions About the Celsius to Kelvin Conversion

1. Why do we add 273.15 when converting Celsius to Kelvin?

The Kelvin scale starts from absolute zero, which is -273.15°C. To shift Celsius values to the Kelvin scale, we add 273.15.

2. Is there a difference between Kelvin and Celsius scales?

Yes, the Celsius scale is based on water's freezing and boiling points, while Kelvin is an absolute scale starting from absolute zero.

3. Can the Kelvin scale have negative values?

No, since the Kelvin scale starts at absolute zero (0 K), it cannot have negative values.

4. Is 0°C the same as 0 K?

No, 0°C is equivalent to 273.15 K. The Celsius scale has negative values, while Kelvin starts at zero.

5. Who uses the Kelvin scale?

Kelvin is widely used in scientific fields such as physics, chemistry, and astronomy, where absolute temperature measurements are required.
