The conversion formula from Celsius to Kelvin is:
K = °C + 273
K = °C - 273
K = °C + 32
K = °C - 32

The relationship between the Celsius and Fahrenheit scales is given by the formula:
°F = (9/5) × °C + 32
°F = (5/9) × °C - 32
°C = (9/5) × (°F - 32)
°C = (5/9) × (°F + 32)

The Kelvin scale is an absolute temperature scale because:
It has a fixed zero point at absolute zero
It uses the properties of water for reference
It is widely used in everyday life
It is based on the properties of gases
