What is the formula for converting Celsius to Fahrenheit?

The formula for converting Celsius to Fahrenheit is correctly represented by the expression in the chosen option: F = (C × 9/5) + 32.

This formula works by first taking the Celsius temperature, multiplying it by the conversion factor of 9/5, which adjusts the scale to account for the different increments of temperature. After scaling the Celsius value, 32 is added, which aligns the zero point of the Fahrenheit scale with its corresponding temperature in Celsius. This adjustment is crucial because the freezing point of water is 0°C (32°F) and the boiling point is 100°C (212°F).

The other formulas presented do not accurately portray the relationship between Celsius and Fahrenheit. For instance, multiplying by 5/9 would incorrectly suggest the relationship is inversed. Additionally, the expression C + 32 multiplied by 9/5 does not correspond to the standard conversion process, and the option that simply subtracts 32 would not yield the correct conversion to Fahrenheit. Understanding this formula is essential for aviation maintenance applications, where accurate temperature readings can influence safety and performance.
