What is the formula for converting Fahrenheit to Celsius?

The formula for converting Fahrenheit to Celsius is indeed C = (F - 32) / 1.8. This formula is derived from the relationship between the two temperature scales.

When converting Fahrenheit to Celsius, you first subtract 32 from the Fahrenheit temperature. This subtraction adjusts for the difference in the starting points of the two scales; for example, 32°F is equivalent to 0°C, serving as the freezing point of water. After this adjustment, you divide the result by 1.8 because the size of the degree in Celsius is different from the degree in Fahrenheit. Specifically, a change of one degree Celsius corresponds to a change of 1.8 degrees Fahrenheit.

This relationship captures how the two scales are calibrated differently, enabling an accurate conversion between them. Understanding this formula is essential for anyone needing to switch temperature readings, whether in scientific contexts or everyday life.
