What is the normal temperature for a human in fairehnheit and Celsius?

Answer 1

Most sources list 37 deg C and 98.6 deg F as normal.

This is an old figure established in the 1800's and most likely not accurate. The true normal probably is a range affected by gender, age, time of day, place in menstrual cycle and other factors. According to recent research 98.6F/ 37C is probably either at the high end of normal or frankly high with most people being lower most of the time.
