How to convert Fahrenheit to Celsius
Temperature scales have different zero points, so you cannot simply multiply. Use this formula:
Worked example: 37 °F to °C
- Start with the value: 37 °F
- Apply the formula above.
- Result: 37 °F = 2.77778 °C

About Fahrenheit and Celsius
What is a fahrenheit (°F)?
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F. It is used in the US and on many medical thermometers (normal body temperature is 98.6 °F).
What is a celsius (°C)?
The Celsius scale sets 0 °C as the freezing point and 100 °C as the boiling point of water at sea level. Bangladesh uses Celsius for weather.
Quick mental trick: to estimate °F from °C, double the Celsius value and add 30 (e.g. 30 °C ≈ 90 °F). Normal body temperature is 37 °C (98.6 °F); a fever starts around 38 °C (100.4 °F).
Where fahrenheit to celsius conversion is used
Temperature conversions are needed for weather reports, cooking and baking, body temperature, science labs and air-conditioner settings. Converting between Fahrenheit and Celsius is especially common when you compare products, read foreign specifications, or fill in forms that expect a specific unit.
