How to convert Celsius to Kelvin
Temperature scales have different zero points, so you cannot simply multiply. Use this formula:
Worked example: 37 °C to K
- Start with the value: 37 °C
- Apply the formula above.
- Result: 37 °C = 310.15 K

About Celsius and Kelvin
What is a celsius (°C)?
The Celsius scale sets 0 °C as the freezing point and 100 °C as the boiling point of water at sea level. Bangladesh uses Celsius for weather.
What is a kelvin (K)?
Kelvin is the SI unit of temperature. It starts at absolute zero (0 K = −273.15 °C) and is used in physics and chemistry.
Quick mental trick: to estimate °F from °C, double the Celsius value and add 30 (e.g. 30 °C ≈ 90 °F). Normal body temperature is 37 °C (98.6 °F); a fever starts around 38 °C (100.4 °F).
Where celsius to kelvin conversion is used
Temperature conversions are needed for weather reports, cooking and baking, body temperature, science labs and air-conditioner settings. Converting between Celsius and Kelvin is especially common when you compare products, read foreign specifications, or fill in forms that expect a specific unit.
