Definition of Fahrenheit

1. Adjective. Describing a temperature scale originally defined as having 0 °F as the lowest temperature obtainable with a mixture of ice and salt, and 96 °F as the temperature of the human body, and now defined with 32 °F equal to 0 °C, and each degree Fahrenheit equal to 5/9 of a degree Celsius or 5/9 kelvin. ¹

Medical Definition of Fahrenheit

1. A measurement of temperature commonly used in the U.S.A. Normal body temperature is considered to be 98.6 degrees Fahrenheit or 37 degrees Celsius. Body temperature can vary 1/2 to 1 degree Fahrenheit above or below 98.6 f. And still be considered normal. Body temperature varies with many factors including level of activity. To convert a Fahrenheit temperature to Celsius use: C = (F-32) x 5/9. To convert a Celsius temperature to Fahrenheit use: F = (C x 9/5) + 32 (27 Sep 1997)
