What is Celsius (°C)?
The Celsius scale is a metric system unit for temperature. It is based on the freezing and boiling points of water.
Key Facts About Celsius
- 0 °C = Freezing point of water.
- 100 °C = Boiling point of water (at 1 atm).
- Abbreviation: °C.
- Used in: Weather forecasts, cooking, and daily measurements.
What is Kelvin (K)?
The Kelvin scale is the SI base unit for temperature, primarily used in science. It starts from absolute zero, the theoretical lowest possible temperature.
Key Facts About Kelvin
- 0 K = Absolute zero = -273.15 °C.
- No negative values exist in Kelvin.
- Abbreviation: K.
- Used in: Physics, chemistry, thermodynamics, and space science.
Celsius to Kelvin Conversion Formula
Formula:
K = °C + 273.15
Celsius to Kelvin Conversion Example
- 0 °C to K
Step 1: Formula = K = °C + 273.15
Step 2: Substitute = 0 + 273.15
Step 3: Result = 273.15 K
- 25 °C to K
Step 1: K = °C + 273.15
Step 2: Substitute = 25 + 273.15
Step 3: Result = 298.15 K
- 100 °C to K
Step 1: K = °C + 273.15
Step 2: Substitute = 100 + 273.15
Step 3: Result = 373.15 K
Kelvin to Celsius Conversion Formula
Formula:
°C = K - 273.15
Kelvin to Celsius Conversion Example
- 273.15 K to °C
Step 1: Formula = °C = K - 273.15
Step 2: Substitute = 273.15 - 273.15
Step 3: Result = 0 °C
- 300 K to °C
Step 1: °C = K - 273.15
Step 2: Substitute = 300 - 273.15
Step 3: Result = 26.85 °C
- 373.15 K to °C
Step 1: °C = K - 273.15
Step 2: Substitute = 373.15 - 273.15
Step 3: Result = 100 °C
