Celsius to Kelvin

Celsius to Kelvin FAQ

What is the formula to convert Celsius to Kelvin?

To convert Celsius to Kelvin, you use the formula: $$ K = C + 273.15 $$ where ( K ) is the temperature in Kelvin and ( C ) is the temperature in Celsius.

Why do we add 273.15 when converting Celsius to Kelvin?

We add 273.15 when converting Celsius to Kelvin because 0 Kelvin (absolute zero) is equivalent to -273.15 degrees Celsius. This value represents the lowest limit of the thermodynamic temperature scale.

How do you convert 25 degrees Celsius to Kelvin?

To convert 25 degrees Celsius to Kelvin, you apply the formula: $$ K = 25 + 273.15 = 298.15 \text{ K} $$

What is the Kelvin temperature scale used for?

The Kelvin temperature scale is used in scientific measurements and calculations because it is an absolute scale starting at absolute zero, where molecular motion stops. This scale is essential in thermodynamics, physics, and other sciences.

Can temperatures in Kelvin be negative?

No, temperatures in Kelvin cannot be negative. The Kelvin scale starts at absolute zero (0 K), the lowest possible temperature, where all thermal motion ceases. Thus, any temperature in Kelvin is always a positive value or zero.
