Taking a temperature. Boy with a digital thermometer in his mouth. The reading on the thermometer says that the boy's body temperature is at 98.8 degrees Fahrenheit, which is about 37 degrees Celsius and is normal. A body temperature above 37 degrees Celsius would indicate that the boy has a fever (pyrexia), although temperatures vary with time and from person to person.
