Celsius to Kelvin Converter
Celsius to Kelvin Converter
The Celsius to Kelvin Converter is a free online tool that instantly converts temperature values from Celsius (°C) to Kelvin (K). Whether you’re a student, scientist, engineer, or simply curious, this calculator helps you understand temperature in the Kelvin scale — a critical unit used in physics, chemistry, and thermodynamics.
What is Celsius to Kelvin Conversion?
The Celsius and Kelvin scales are both metric temperature scales, but while Celsius is commonly used in everyday life, Kelvin is the standard unit in scientific fields. The Kelvin scale starts at absolute zero — the point where molecular motion theoretically stops. To convert Celsius to Kelvin, you simply add 273.15 to the Celsius value.
Formula Used
Kelvin (K) = Celsius (°C) + 273.15
For example, 25°C is equal to 298.15 K.

Frequently Asked Questions (FAQs)
1. What is the Kelvin scale used for?
The Kelvin scale is used in scientific research, especially in physics and thermodynamics, because it starts from absolute zero, the coldest possible temperature.
2. Why do scientists prefer Kelvin over Celsius?
Kelvin provides an absolute reference point (zero Kelvin) and is part of the International System of Units (SI), making it ideal for formulas and calculations.
3. Can Kelvin be negative?
No, Kelvin values are never negative because the scale starts from absolute zero (0K), where all thermal motion ceases.
4. Is 273.15K always equal to 0°C?
Yes. This is a fixed scientific value and forms the basis of the Kelvin scale.
5. How accurate is this calculator?
This tool uses the standard conversion formula, so it is accurate to two decimal places unless the input is unrealistic or mistyped.
