Enter a value in any field to instantly convert between **Celsius (°C)**, **Kelvin (K)**, and **Fahrenheit (°F)**. Celsius (°C) Kelvin (K) Fahrenheit (°F) Calculation Steps: Enter a value to see the step-by-step conversion. How to Convert Celsius to Kelvin The conversion from Celsius (°C) to Kelvin (K) is the simplest temperature conversion because the *size* of one degree Celsius is identical to the size of one Kelvin. The only difference is their "zero" point. The Formula (Celsius to Kelvin) To convert from Celsius to Kelvin, you simply add 273.15. K = °C + 273.15 Example: Convert 100°C (the boiling point of water) to Kelvin. 100 °C + 273.15 = 373.15 K The Formula (Kelvin to Celsius) To convert from Kelvin to Celsius, you subtract 273.15. °C = K - 273.15 What is Absolute Zero? The Kelvin scale is an "absolute" scale, meaning its zero point (0 K) is **Absolute Zero**. This is the theoretical temperature at which all atomic and molecular motion ceases. There is no temperature colder than 0 K, which is why the Kelvin scale has no negative numbers. Celsius and Fahrenheit are "relative" scales, as their zero points (0°C and 0°F) were set for convenience (e.g., the freezing point of water).
