Conversion

I have been giving out some incorrect information here. The question is what does a 2 degree Celsius increase convert to in Fahrenheit. Here is the correct formula -

°F to °C Deduct 32, then multiply by 5, then divide by 9

°C to °F Multiply by 9, then divide by 5, then add 32

Example: 68F: 68 - 32 = 36; 36 * 5 = 180; 180/9 = 20C
20 + 2 = 22; 22 * 9 = 198; 198/5 = 39.6; 39.6 + 32 = 71.6F

Recapping: a 2 degree Celsius increase on 68 degrees Fahrenheit equals 71.6 degrees Fahrenheit. The question surrounds the increase in temperatures due to global warming.
