How to convert degrees Celsius to kelvins

Temperature scales start from different zero points, so the conversion is not a single multiplication. Use the formula above: K = °C + 273.15. For example, 20 c is 293.15 k.

Quick estimate

Work through the formula above for exact results; for weather temperatures, “double and add 30” (°C to °F) or “take 30 and halve” (°F to °C) gets within a few degrees.

Where it comes up

Temperature conversions come up in weather forecasts, cooking and oven settings, body temperature and science classes.
