Question: The temperature of body of a healthy man is 98.4°F. What would be the reading in Celsius scale?

Given,

Temperature in Fahrenheit scale, F = 98.4°F

Temperature in Celsius scale, C = ?

We know,

C / 5 =  F-32 / 5

C / 5 =  (98.4 – 32) / 9

or, C = 36.89 °C

Ans: 36.89 °C

 

Note: There are three scales of temperature in use — Celsius, Fahrenheit and Kelvin scale. The units of temperature of these three scales are °C, °F and K respectively. The lower fixed point in Celsius scale is 0°C, in Fahrenheit scale 32°F and in Kelvin scale it is 273K. The upper fixed point in Celsius scale is 100°C, in Fahrenheit scale 212°F and in Kelvin scale it is 373K.
