How to Convert Fahrenheit to Celsius in JavaScript in Hindi.

How to Convert Fahrenheit to Celsius in JavaScript in Hindi.

Here is how to convert °F to °C. This is actually Fahrenheit to Celsius and not Fahrenheit to Celcius, though the mis-spellings of the temperature scales are common. So are the temperature scales, which are used to measure room temperature, body temperature, set thermostats, and take scientific measurements. 

Temperature Conversion Formula

  1. Take the °F temperature and subtract 32.
  2. Multiply this number by 5.
  3. Divide this number by 9 to obtain your answer in °C.
The formula to convert °F to °C is:
T(°C) = (T(°F) - 32) × 5/9
which is
T(°C) = (T(°F) - 32) / 1.8
