Formula used: K = °C + 273.15
What is Celsius to Kelvin Calculator?
A Celsius to Kelvin Calculator is a fast online tool that helps you convert any temperature value from degrees Celsius (°C) to Kelvin (K). It is especially useful for students, teachers, and professionals who work with temperature scales in science or engineering.
Celsius is a common unit for measuring temperature, with water freezing at 0°C and boiling at 100°C. Kelvin, on the other hand, is the SI unit for thermodynamic temperature, starting at absolute zero. This calculator instantly provides you the Kelvin equivalent of any given Celsius value.
Formula or Logic Behind Celsius to Kelvin Calculator
The conversion from Celsius to Kelvin is simple and based on an internationally accepted formula:
K = °C + 273.15
This means you just add 273.15 to your Celsius temperature to get the Kelvin value. For example, 25°C + 273.15 = 298.15 K. This formula ensures that 0 K represents absolute zero, the coldest possible temperature.
Common Celsius to Kelvin Conversion Table
