Converting temperatures from Fahrenheit to Celsius is a common task in various fields, including science, engineering, and daily life. The formula to convert Fahrenheit (°F) to Celsius (°C) is: °C = (°F - 32) × 5/9. For example, to convert 68°F to Celsius: (68 - 32) × 5/9 = 20°C. This means that 68 degrees Fahrenheit is equivalent to 20 degrees Celsius. Understanding this conversion is essential, especially in regions where both temperature scales are used. For a quick approximation, subtract 30 from the Fahrenheit value and then divide by 2; however, this method is less precise than using the exact formula. citeturn0search1 Accurate temperature conversion ensures clear communication and understanding across different measurement systems.
