In order to convert 120 degrees Celsius to its equivalent temperature in degrees Fahrenheit, you need to apply the equation (9/5)C + 32 = F, where C is the temperature in degrees Celsius and F is the temperature in degrees Fahrenheit. The values 9/5 and 32 are constant, and they do not change regardless of the numeric value of the temperature. In this case, C = 120, so the formula becomes [(9/5) x (120)] + 32. The answer is 248 degrees Fahrenheit.
- Multiply the temperature in degrees Celsius by nine
To convert any temperature, take it in degrees Celsius and multiply it by nine. This factor is constant because it is the numerator of the constant improper fraction 9/5. In this case, multiply 120 degrees Celsius by nine. This will result in a figure of 1080.
- Divide the product by five
Divide 1080 by the denominator, five. The divisor in this equation is constant regardless of what temperature is involved. The resulting equation for this example is 1080 ÷ 5 = 216.
- Add 32 to the quotient
This number, 32, is another constant for this equation. You need to add 32 to the quotient, which in this case is 216. The final answer is therefore 248 degrees Fahrenheit, which is the equivalent of 120 degrees Celsius.
