Kelvin (K)

Temperature

SI definition

Traceable to the kelvin, defined by fixing the Boltzmann constant at 1.380 649 × 10⁻²³ J/K. Celsius and Fahrenheit are exact affine transforms of the kelvin scale.

Celsius (°C)

Temperature

SI definition

t/°C = T/K − 273.15. The degree Celsius has exactly the same magnitude as the kelvin.

How to Convert Kelvin to Celsius

This conversion uses an offset formula, so it cannot be described by a single multiplication factor.

الصيغة: °C = K - 273.15

العكس: K = °C + 273.15

مثال خطوة بخطوة

Start with your value in Kelvin. For example: 5 K
Apply °C = K - 273.15
The result is: -268.15 °C

حول Kelvin

The Kelvin scale is the SI unit of temperature that starts at absolute zero (−273.15°C). It is used extensively in scientific research.

حقيقة ممتعة: At 0 Kelvin (absolute zero), all molecular motion stops. It has never been fully achieved in a laboratory.

الاستخدامات الشائعة: physics, astronomy, chemistry.

حول Celsius

The Celsius scale sets 0°C as the freezing point and 100°C as the boiling point of water at standard pressure. It is used by most countries worldwide.

حقيقة ممتعة: Anders Celsius originally proposed a scale where 100° was freezing and 0° was boiling—it was later reversed!

الاستخدامات الشائعة: weather, cooking, science.
