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.

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.

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.

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

How many degree Fahrenheit are there in 10 degree Celsius?

18°F The degree intervals on the Celsius scale number 100 between the freezing and boiling points of water (0° and 100°), whereas there are 180 intervals between them in the Fahrenheit scale (32° and 212°). So the conversion between scales is 1° C = 1.8°F (9/5°). A change of 10°C is equal to a change of 18°F. (10x1.8=18)


How many Fahrenheit degrees are in a celsius degree?

A "degree" in Celsius is 1.8 times as large an interval as a "degree" in Fahrenheit. So changes in temperature will be 1.8 times as large on the Fahrenheit scale than on the Celsius scale. Explanation In Fahrenheit, freezing is 32° and boiling is 212° so there are 180 degrees in between. In the Celsius system there are only 100 (larger) degrees between those marks, so the ratio is 180/100 or 1.8 Fahrenheit degrees = 1 Celsius degree. Example : Water freezes at 0 °C, which is the same as 32 °F. If the water temperature is raised by 10 degrees to 10° C, the Fahrenheit scale will indicate a change of 18 degrees, to 50 °F. Conversion Formulas °F = (1.8 x °C) +32 and °C = (°F-32) / 1.8
