Celsius to Kelvin Calculator

Convert temperatures from Celsius (°C) to Kelvin (K) with our accurate calculator. This tool is essential for scientific calculations, thermodynamics, and understanding absolute temperature scales.

Understanding Celsius and Kelvin

Celsius and Kelvin are two important temperature scales:

• Celsius (°C): Based on water’s freezing (0°C) and boiling (100°C) points
• Kelvin (K): The SI unit of temperature, based on absolute zero

Key points about Kelvin:

• No negative values (starts at absolute zero)
• Used extensively in scientific calculations
• No degree symbol (just “K”)
• Zero Kelvin = -273.15°C (absolute zero)

Conversion Formula

The formula to convert Celsius to Kelvin is:

$$\text{Kelvin} = \text{Celsius} + 273.15$$

Common reference points:

• Water freezing: 0°C = 273.15K
• Room temperature: 20°C = 293.15K
• Water boiling: 100°C = 373.15K

Common Use Cases

1. Scientific Research

   • Chemical reactions
   • Physical properties
   • Thermodynamic calculations

2. Engineering

   • Heat transfer
   • Material properties
   • System design

3. Education

   • Physics experiments

Technical Notes

• The calculator prevents entry of temperatures below absolute zero (-273.15°C)
• Results are rounded to 2 decimal places
• The Kelvin scale has no negative values
• For scientific work, verify results with calibrated instruments
• Remember: temperature differences are the same in both scales (a change of 1°C = a change of 1K)
