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.
- Rewrite the problem with the appropriate number
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.
- Solve the parenthesis
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 by the fraction
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.
