140 degrees in Fahrenheit is 60 degrees Celsius. There is a mathematical formula, °C = (°F - 32) × 5/9, which can be used to convert any temperature in Fahrenheit to Celsius.Continue Reading
Write the equation with the appropriate temperature for Fahrenheit that you wish to convert. It appears as the following equation: °C = (140°- 32) × 5/9.
The next step is to solve the numbers within the parenthesis by subtracting 32 from your Fahrenheit temperature. This may result in a negative number. In our example the parenthesis results in 108. Here is an example: °C = (140°- 32) × 5/9.
Multiply 108 by 5 and divide the resulting answer by 9. In this equation, 108 times 5 results in 540. The 540 is then divided by 9 which results in 60 degrees.
