The human body temperature 
is gauged using two scales. A healthy body registers 
at 98.4°F on the Fahrenheit scale, within the range of 
95–110°F on a doctor’s thermometer. 
On the Celsius scale, the standard body 
temperature is 37°C.

In 1715, German physicist Gabriel Daniel Fahrenheit created a
precise thermometer utilizing mercury within 
a glass tube. The scale on the thermometer 
was named after him. Nowadays, temperature 
readings are commonly taken on the Celsius scale.
