Convert kelvin to celsius Online

Convert Temperature Units Online with Kelvin (K) to Celsius (°C) Conversion

Convert Kelvin to Celsius using the exact conversion factor. This page provides the formula, reference values, and practical context for engineering, technical calculations, and professional measurement use.

Conversion Formula

°C = K − 273.15

Temperature conversions use an offset formula, not a single multiplier. Apply the relationship shown above (for example Kelvin (K) to Celsius (°C)) so absolute scale differences (such as the 273.15 K offset for Celsius) are handled correctly.

Example

Convert 1 K to C.

  • Step 1: Write the formula: °C = K − 273.15
  • Step 2: Substitute: K = 1
  • Step 3: Result: -272.15 C
So, 1 K = -272.15 C.
