To convert Celsius to Fahrenheit, use the formula: °F = (°C × 9/5) + 32. For example, 20°C = (20 × 9/5) + 32 = 68°F.
To convert Fahrenheit to Celsius, use the formula: °C = (°F - 32) × 5/9. For example, 68°F = (68 - 32) × 5/9 = 20°C.
Celsius and Fahrenheit are two different temperature scales. Celsius is based on the freezing (0°C) and boiling (100°C) points of water, while Fahrenheit sets these points at 32°F and 212°F respectively. Celsius is used worldwide in most countries, while Fahrenheit is primarily used in the United States.
The United States is the only major country that still uses Fahrenheit for everyday temperature measurements. A few other countries like the Bahamas, Belize, and the Cayman Islands also use Fahrenheit alongside Celsius.
The normal human body temperature of 98.6°F is exactly 37°C when converted. The difference in decimal places is due to the different scales and measurement precision between the two systems.
Our temperature converter provides results accurate to one decimal place, which is sufficient for most everyday applications. For scientific or medical purposes requiring higher precision, more specialized equipment may be needed.
