Kelvin (K)

Definition:
The Kelvin scale is the SI base unit of temperature used in physics, chemistry, and engineering.
It starts from absolute zero (0 K), the lowest possible temperature where all molecular motion stops.

Key Facts About Kelvin

• Exact value: 0 K = -273.15°C
• Relationship to other units: 1 K = 1°C difference
• Common abbreviation: K
• Notation tips: Kelvin values are written without the degree symbol.

Degree Celsius (°C)

Definition:
The Degree Celsius scale measures temperature relative to the freezing and boiling points of water.
It’s the most widely used temperature scale in daily life, weather forecasting, and scientific studies.

Key Facts About Degree Celsius

• Exact value: 0°C = 273.15 K 
• Relationship to other units: 1°C = 1 K difference
• Common abbreviation: °C
• Notation tips: Always include the degree symbol (°) before the “C”.

Kelvin to Degree Celsius Conversion Formula

Formula:

°C = K - 273.15

K to °C Conversion Examples

Example 1: 273.15 K to °C
Step 1: Formula = °C = K - 273.15
Step 2: Substitute = 273.15 - 273.15
Step 3: Result = 0°C

Example 2: 298.15 K to °C
Step 1: °C = K - 273.15
Step 2: Substitute = 298.15 - 273.15
Step 3: Result = 25°C

Example 3: 373.15 K to °C
Step 1: °C = K - 273.15
Step 2: Substitute = 373.15 - 273.15
Step 3: Result = 100°C

Degree Celsius to Kelvin Conversion Formula

Formula:

K = °C + 273.15

°C to K Conversion Examples

Example 1: 0°C to K
Step 1: Write the formula = K = °C + 273.15
Step 2: Substitute = 0 + 273.15
Step 3: Result = 273.15 K

Example 2: -40°C to K
Step 1: K = °C + 273.15
Step 2: Substitute = -40 + 273.15
Step 3: Result = 233.15 K

Example 3: 100°C to K
Step 1: K = °C + 273.15
Step 2: Substitute = 100 + 273.15
Step 3: Result = 373.15 K
