1. What is the Kelvin Scale?

The Kelvin scale is an absolute temperature scale where 0 K represents absolute zero, the theoretical lowest possible temperature. It's widely used in scientific measurements and calculations.

2. Conversion Formula

The conversion from Celsius to Kelvin is straightforward:

Where:

• \( K \) — Temperature in Kelvin
• \( °C \) — Temperature in Celsius

3. Importance of Kelvin

Details: Kelvin is essential in scientific work because it's an absolute scale with no negative values. It's used in physics, chemistry, astronomy, and other sciences where precise temperature measurements are required.

4. Using the Calculator

Tips: Simply enter the temperature in Celsius degrees and click calculate. The converter will display the equivalent temperature in Kelvin.

5. Frequently Asked Questions (FAQ)

Q1: Why is 273.15 used in the conversion?
A: This is the exact difference between the Celsius and Kelvin scales, as absolute zero is -273.15°C.

Q2: Are Celsius and Kelvin degree sizes the same?
A: Yes, a 1°C change equals a 1 K change, only the zero points differ.

Q3: When should I use Kelvin instead of Celsius?
A: Use Kelvin for scientific calculations, especially when dealing with gas laws, thermodynamics, or any situation where absolute temperature matters.

Q4: What is absolute zero in Kelvin?
A: Absolute zero is 0 K, the temperature at which all thermal motion ceases.

Q5: Can temperature be negative in Kelvin?
A: No, the Kelvin scale has no negative values as it starts at absolute zero.
