Celsius to Kelvin Converter
Convert temperature from Celsius to Kelvin.
Calculator
Formula
Explanation
While the formula is straightforward, it’s worth noting that in some contexts, particularly for quick approximations, the value 273 is used instead of 273.15 (e.g., 25°C ≈ 298 K). However, this introduces a slight error of 0.15 K and is less precise. The exact formula, K = °C + 273.15, is universally accepted for scientific and engineering applications where accuracy is critical. No other variations of the formula exist, as the Kelvin and Celsius scales have a fixed linear relationship.

Frequently Asked Questions
How do I convert Celsius to Kelvin using the calculator?
To convert Celsius to Kelvin, simply enter the temperature in Celsius into the calculator. The tool will automatically add 273.15 to the Celsius value to provide the equivalent temperature in Kelvin (K = °C + 273.15).
Why does the Kelvin scale start at 273.15 when converting from Celsius?
The Kelvin scale is an absolute temperature scale where 0 K (absolute zero) is the lowest possible temperature. Since 0°C is equivalent to 273.15 K, the conversion formula adds 273.15 to the Celsius value to align with the Kelvin scale.
Can the Celsius to Kelvin converter handle negative temperatures?
Yes, the converter can handle negative Celsius values. For example, -40°C is equal to 233.15 K. However, Kelvin values cannot be negative because absolute zero (0 K) is the lowest possible temperature.
Is there a limit to the Celsius values that can be converted to Kelvin?
Theoretically, there is no upper limit to the Celsius values that can be converted to Kelvin. However, extremely high temperatures may exceed the calculator's display capabilities or practical scientific relevance. The lower limit is -273.15°C, which equals 0 K (absolute zero).
What are some common applications of converting Celsius to Kelvin?
Converting Celsius to Kelvin is essential in scientific fields like physics, chemistry, and astronomy, where absolute temperature measurements are required. It is also used in thermodynamics, gas law calculations, and cryogenics research.
About This Calculator
Celsius to Kelvin Converter
The Celsius to Kelvin Converter is a simple yet essential tool for converting temperature measurements between the Celsius (°C) and Kelvin (K) scales. Kelvin is the base unit of temperature in the International System of Units (SI) and is widely used in scientific research, thermodynamics, and engineering. The conversion is straightforward, as the two scales are offset by a fixed value: 273.15. To convert Celsius to Kelvin, simply add 273.15 to the Celsius temperature. For example, 25°C is equal to 298.15 K (25 + 273.15).
This converter is particularly useful for students, researchers, and professionals who need accurate temperature conversions for experiments, calculations, or data analysis. Unlike the Celsius scale, which sets the freezing point of water at 0°C, the Kelvin scale starts at absolute zero (0 K), the theoretical temperature at which all thermal motion ceases. By using this converter, you can seamlessly switch between these two important temperature scales with precision and ease.
