Question

convert 30 degree Celsius to degree Fahrenheit and 80 degree fahrenheit to degree Celsius

Answer 1

To convert temperatures in degrees Celsius toFahrenheit, multiply by 1.8 (or 9/5) and add 32.

Answer 2

(i) 45°C in °F

Fahrenheit = (Celsius * 1.8) + 32

Fahrenheit = (45 * 1.8) + 32

           = (81) + 32

           = 113

∴ 45°C  = 113°F

(ii) 80°F in °C

Celsius= (Fahrenheit - 32) / 1.8

           = (80 - 32) / 1.8

           = (48) / 1.8

           =  26.6666667

∴ 80°F = 26.6666667°C
