80°F = 262/3°C
To convert Celsius to Fahrenheit, the formula is F = 9/5C + 32.
If the Fahrenheit reading is 3 times the Celsius reading then F = 3C, so
3C = 9/5C + 32 : 6/5C = 32 : C = 262/3. Then F = 3C = 3 x 262/3 = 80

A Celsius degree is 1.8 times the size of a Fahrenheit degree, or 80% larger.
A Celcius degree is 1.8 times as large as a Fahrenheit degree.
To convert a temperature given in Celsius to the same temperature in Fahrenheit degrees: -- multiply 'C' by 1.8 -- add 32 to the answer. 98.6 Celsius = (98.6 times 1.8) plus 32 = 177.48 + 32 = 209.48 Fahrenheit
Multiply 225 times 1.8 then add 32. 437 degrees Fahrenheit
To convert from Celsius to Fahrenheit, first multiply by 1.8, and then add 32. 15 times 1.8 is 27, and 27 plus 32 is 59. Therefore, 15 degrees Celsius equals 59 degrees Fahrenheit.
