Frequently Asked Questions
How do I convert Kelvin to Fahrenheit?
Subtract 273.15, multiply by 9/5, then add 32: °F = (K − 273.15) × 9/5 + 32. For example, 300 K → 26.85 °C → 80.33 °F.
What is 300 K in Fahrenheit?
300 K is 80.33 °F — a warm room or a mild summer day. Ordinary room temperature of 293 K is about 68 °F.
What is the boiling point of water in Kelvin?
373.15 K at standard pressure, which is 100 °C or 212 °F. Freezing is 273.15 K.
Where is Kelvin actually used?
In physics, chemistry and astronomy, where an absolute scale is required — gas laws and thermodynamic equations only work with absolute temperature. It also describes the colour temperature of light bulbs: 2700 K is warm white, 6500 K is daylight.
