Question

What's your normal body temperature? It may not be 98.6°F, the oft-quoted average that was determined in the nineteenth century. A more recent study has reported an average temperature of 98.2°F. What is the difference between these averages, expressed in Celsius degrees?

Answer 1

the difference is 98.6 - 98.2 = 0.4°F

Since °C = 9/5 °F, that's 0.4*1.8 = 0.72°C
