## 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
