Convert K to °C with our scientific temperature converter. Essential for physics, chemistry, and engineering applications.
To convert Kelvin to Celsius, subtract 273.15 from the temperature. For example: 293.15 K = 293.15 - 273.15 = 20°C. Common conversions: 273.15 K = 0°C (freezing point), 373.15 K = 100°C (boiling point), 0 K = -273.15°C (absolute zero).
This converter uses the standard formula (°C = K - 273.15) for converting Kelvin to Celsius.
This Temperature Converter converts Kelvin to Celsius using the standard formula °C = K - 273.15. It provides instant, accurate conversions following international temperature measurement standards.

Canadian students and educators frequently encounter Kelvin values when reading NASA climate datasets, CERN particle physics reports, or Environment Canada's upper-atmosphere research. Converting those figures to Celsius makes the data immediately relatable -- a classroom in Toronto can grasp that 288 K means roughly 15°C, a pleasant spring afternoon, far more intuitively than the raw Kelvin figure.
The Kelvin to Celsius conversion is frequently needed when working with scientific data and laboratory measurements. While Kelvin is the SI base unit for thermodynamic temperature used in scientific work, Celsius is more familiar for everyday applications and is the standard in Canada.
Both scales use the same degree size, with Kelvin simply shifted down by 273.15 units to start at absolute zero instead of water's freezing point. This makes the conversion straightforward - just a simple subtraction to translate between the scientific absolute scale and the practical relative scale.
Converting Kelvin to Celsius is simple with our converter. Follow these easy steps to translate scientific temperature measurements into the familiar Celsius scale.

The SI base unit of thermodynamic temperature, an absolute scale beginning at zero (absolute zero). Used universally in scientific research and calculations.
A relative temperature scale based on water's properties, with 0°C at the freezing point and 100°C at the boiling point. The everyday temperature scale used in Canada.
Temperature measured from absolute zero (0 K), the lowest possible temperature. Kelvin provides absolute temperature measurements.
The unique temperature and pressure where water can exist as solid, liquid, and gas simultaneously. It occurs at 273.16 K (0.01°C), used to define the Kelvin scale.
