About this conversion
Kelvin to Celsius converts scientific temperatures back to the more intuitive Celsius scale. The Kelvin scale (SI base unit) starts at absolute zero — 0 K = −273.15°C — and uses the same degree size as Celsius, making the conversion trivial: just subtract 273.15. Scientists routinely work in Kelvin and convert to Celsius when reporting results for general audiences. Key reference temperatures: 0 K = −273.15°C (absolute zero), 273.15 K = 0°C (ice point), 293 K = 19.85°C (standard room temperature in physics), 310.15 K = 37°C (body temperature), 373.15 K = 100°C (steam point), 5,778 K ≈ 5,505°C (solar surface). Colour temperature in photography is given in Kelvin: daylight is ~5,500 K, incandescent bulbs ~2,700 K.
