Celsius and Fahrenheit are two different temperature scales. To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 and then add 32. For example, 25°C is converted by calculating (25 × 9/5) + 32, which equals 77°F. To convert Fahrenheit back to Celsius, subtract 32 from the Fahrenheit temperature and multiply the result by 5/9. These formulas allow the converter to calculate the result quickly and accurately.
