The conversion from deg C to Deg F is 9/5(degC) + 32. I don't understand the question as posed.
2 C = 36,5 F
8 C = 46,4 F
2 C - 8 C is -6 C = 21,2 F
(if it was two degrees Celsius yesterday and the temperature dropped eight degrees overnight it would now be minus six degrees Celsius or about twenty one degrees Fahrenheit)
28 degrees Fahrenheit is -2.22 degrees Celsius.
28 degrees Celsius = 82.4 degrees Fahrenheit.
28 Fahrenheit is approximately -2.2 degrees Celsius.
28 degrees Fahrenheit is approximately -2 degrees Celsius.
28-30 degrees Celsius is approximately 82.4-86 degrees Fahrenheit.
28 degrees Fahrenheit is -2.22 degrees Celsius.
28 degrees Celsius = 82.4 degrees Fahrenheit.
28 degrees Fahrenheit = -2.2 degrees Celsius.
28 Fahrenheit is approximately -2.2 degrees Celsius.
28 degrees Celsius = 82.4 degrees Fahrenheit
-28 degrees Celsius is equal to -18.4 degrees Fahrenheit.
28 degrees Celsius = 82.4 degrees Fahrenheit
28 degree Celsius = 82.4 degree Fahrenheit
-28 degrees Celsius = -18.4 degrees Fahrenheit.
28 degrees Celsius is equivalent to 82.4 degrees Fahrenheit.
28 degrees Fahrenheit is approximately -2 degrees Celsius.
28 degrees Celsius = 82.4 degrees Fahrenheit
