Yes, a child with a body temperature of 38.7 degrees Celsius does have a fever. The normal body temperature is typically around 98.6 degrees Fahrenheit (37 degrees Celsius). Therefore, a temperature of 38.7 degrees Celsius is above the normal range, indicating that the child is experiencing a fever.
To convert the temperature from degrees Celsius to Kelvin, you can use the formula:
K = °C + 273.15
In this case:
K = 38.7 + 273.15 = 311.85
So, the child’s temperature in Kelvin is approximately 311.85 K.
