**Temperature Converter — Convert °C, °F, K, °R Instantly**

Temperature conversion is one of the most frequently searched unit conversions online. Our converter handles all four major temperature scales simultaneously with instant updates.

**Formulas**

°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
°R = K × 9/5

Frequently Asked Questions

°F = (°C × 9/5) + 32. Example: 20°C = (20 × 1.8) + 32 = 68°F.
Absolute zero (0 K = −273.15°C = −459.67°F) is the lowest possible temperature where all molecular motion stops.
Yes. The Kelvin scale uses the same degree size as Celsius but starts at absolute zero. K = °C + 273.15.
98.6°F (37°C). Normal range is 97°F–99°F. Fever is generally above 100.4°F (38°C).
Room temperature is typically 20–22°C (68–72°F). ISO standard defines it as 23°C (73.4°F).
