-18 degree Fahrenheit is how many degree celsius?

Answer 1

The formula to convert Celsius degrees to Fahrenheit is 9/5C + 32. Multiply 18 degrees Celsius times 9; then divide the answer by 5; then add 32. So 18 degrees Celsius would be 64.4 degrees Fahrenheit.

Answer 2

The formula to convert Fahrenheit to Celsius (or Centigrade) is of the form:

Centigrade = 5/9 (Fahrenheit - 32).

So, C = 5/9 ( -18 - 32)

C = 5/9 ( -50)

C = -250/9

C = -27.777

So, your answer is 18 degrees Fahrenheit equals -27.777 degrees Centigrade.

Hope this helps.

Answer 3

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32
In this case, the answer is about -0.4 degrees Fahrenheit.

Answer 4

Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32
In this case, the answer is about -0.4 degrees Fahrenheit.

Answer 5

To convert from C to F, multiply the C temperature by 9/5 and then add 32: 18oC = (9/5 x 18) + 32 = 32.4 + 32 = 64.4oF
