Frequently Asked Questions
To convert Celsius to Fahrenheit, multiply the temperature by 1.8 (or 9/5) and add 32. For example, (20°C × 1.8) + 32 = 68°F. This tool does this calculation for you instantly.
To convert Fahrenheit to Celsius, subtract 32 from the temperature and then multiply by 0.5556 (or 5/9). The formula is: C = (F - 32) * 5/9.
Kelvin (K) is the SI base unit for thermodynamic temperature. It starts at absolute zero (0 K), the theoretical point where all molecular motion stops, making it essential for scientific calculations where negative temperatures are problematic.
Historically, the scale was called "Centigrade" because it had 100 degrees between freezing and boiling water. In 1948, it was officially renamed to "Celsius" to honor astronomer Anders Celsius, but the values remain identical.
Average normal body temperature is typically cited as 98.6°F (37°C). However, modern studies suggest it can vary slightly, often ranging between 97°F (36.1°C) and 99°F (37.2°C).
Yes, the converter handles negative values correctly. For example, -40°C is equal to -40°F, which is the only point where the two scales intersect.
