How to calculate fever Fahrenheit to Celsius?

In a Digital Thermometer, you can make changes from Fahrenheit to Celsius but in the case of a glass thermometer, some have both Fahrenheit and Celsius or It has just Celsius or Fahrenheit.

We are not able to understand how much temperature means, To solve this you can do step manually.

First We Will check How to calculate Manually Method

Convert Fahrenheit to Celsius

Formula (°F − 32) × 5/9 = °C

“F” indicates to Fahrenheit

“C” indicates to Celsius

We will show you some calculation

102 °F Fahrenheit to Celsius?

(102°F – 32) × 5/9 = 38.89°C

103 °F Fahrenheit to Celsius?
(103°F − 32) × 5/9 = 39.44°C

Convert Celsius to Fahrenheit

Formula (°C × 9/5) + 32 = °F

“C” indicates to Celsius

“F” indicates to Fahrenheit

39.4 °C to Fahrenheit ?
(39.4°C × 9/5) + 32 = 102.92°F
38.1 °C to Fahrenheit ?
(38.1°C × 9/5) + 32 = 100.58°F

Through this way you can convert Fahrenheit to Celsius.


The Body temperature rises because of the Hypothalamus which is part of the brain.

Fever is a response toward viruses, flu, bacteria infection. In most cases, the fever goes in 2 to 3 days.

In a child fever can be serious so consult with a doctor, some immunization also causes fever.
