By using a thermometer or taking your hands to your head and if It's hot, bingo. Fever.

I define fever as anything over 99 degrees F, but that's because my normal temp is around 97. Most people define a fever as being anything over 101. Although 100-101 is also sometimes considered a "Low Grade fever" The average normal body temperature is 98.6 Hope this is helpful.
