To convert Celsius to Fahrenheit, which formula should be used?

To convert Celsius to Fahrenheit, the correct formula is (Celsius × 9/5) + 32. This formula effectively translates the temperature from the Celsius scale, which is based on the freezing and boiling points of water (0°C and 100°C, respectively), to the Fahrenheit scale, which is based on a different standard where water freezes at 32°F and boils at 212°F.

In this formula, the multiplication by 9/5 (or 1.8) adjusts the Celsius temperature to the Fahrenheit scale, and then adding 32 shifts the result to account for the different starting point of the Fahrenheit scale. This ensures that the relative temperatures are accurately represented across both scales, allowing for precise temperature conversions.

Understanding this formula is part of fundamental temperature conversion knowledge, which is crucial in various applications, including scientific calculations, cooking, and weather forecasting.
