Conversion Formula
Celsius → Fahrenheit: °F = (°C × 9/5) + 32 Fahrenheit → Celsius: °C = (°F − 32) × 5/9 Celsius → Kelvin: K = °C + 273.15 Kelvin → Celsius: °C = K − 273.15
About Celsius to Kelvin Conversions
Converting Celsius (°C) to Kelvin (K) is one of the most common unit conversions. Enter any temperature below for an instant answer.
This conversion uses a non-linear (reciprocal) relationship, so a simple multiplication factor does not apply. The formula section below explains the method, and the reference table shows common converted values.
For reference: this page provides a °C-to-K conversion table covering common values, the exact mathematical formula, and frequently asked questions.
Frequently Asked Questions
How do I convert Celsius to Kelvin?
This conversion is non-linear. Use the calculator above for accurate results, or refer to the formula section on this page.
How many Kelvin are in 1 Celsius?
The relationship between Celsius and Kelvin is non-linear. Use the calculator above or the reference table on this page for specific values.
Is Celsius larger or smaller than Kelvin?
The size relationship between Celsius and Kelvin depends on the input value because this conversion is non-linear (reciprocal).
When would I use Kelvin instead of Celsius?
Use K when the context requires it — Celsius for science and most of the world, Fahrenheit for everyday use in the United States, and Kelvin for scientific calculations where absolute temperature (no negative values) is important.
