18 Fahrenheit to Celsius – What is 18 °F in °C?
18°F is equal to -7.78°C. To convert Fahrenheit to Celsius, you can use the formula C = (F - 32) x 5/9. In this case, C = (18 - 32) x 5/9, which simplifies to C = -7.78. So if you have a temperature of 18°F and need to know the equivalent temperature in Celsius, it is -7.78.
On our website, you can find a temperature converter and formula for converting Fahrenheit to Celsius. Celsius, also known as centigrade, is denoted by the symbol °C, while Fahrenheit is denoted by °F. In this article, we'll provide you with all the information you need to know about temperature conversion, including the conversion of 18 °F to °C.
A brief overview of Celsius and Fahrenheit scales
The Celsius and Fahrenheit scales are the primary temperature scales used in different countries and industries. The Celsius scale is based on water's freezing and boiling points, with 0 degrees Celsius (°C) being the freezing point and 100 degrees Celsius (°C) being the boiling point.
On the other hand, the Fahrenheit scale is also based on water's freezing and boiling points, with 32 degrees Fahrenheit (°F) being the freezing point and 212 degrees Fahrenheit (°F) being the boiling point. The ability to convert temperatures from one scale to another, such as from 18 Fahrenheit to Celsius, is crucial for accurate measurement and effective communication in various fields.
Fahrenheit to Celsius Conversion Formula
The formula for converting Fahrenheit to Celsius is:
°C = (°F - 32) ÷ 1.8
In this formula, there are two key variables: °C and °F.
°F represents the temperature in degrees Fahrenheit that we want to convert to Celsius.
°C represents the temperature in degrees Celsius that we get after converting the temperature from Fahrenheit to Celsius using the formula.
This formula is widely accepted and approved by scientific organizations and experts in the field of thermodynamics. The formula is based on the relationship between the Celsius and Fahrenheit scales, which are two common temperature scales used in the world.
The Fahrenheit scale was invented by Daniel Gabriel Fahrenheit in the early 18th century. The Celsius scale, on the other hand, was developed in the mid-18th century by Anders Celsius.

Comparison between Celsius and Fahrenheit scales
|Temperature Scale||Freezing Point||Boiling Point||Conversion Formula||18°F to °C Conversion|
|Celsius (C)||0°C||100°C||°C = (°F - 32) ÷ 1.8||18°F = -7.78°C|
|Fahrenheit (F)||32°F||212°F||°C=(°F-32)÷1.8||18°C= 64.4°F|
As you can see, the conversion formula for Fahrenheit to Celsius is °C = (°F - 32) ÷ 1.8, while the conversion formula for Celsius to Fahrenheit is °F = (°C × 1.8) + 32. Therefore, to convert 18 degree Fahrenheit to Celsius, you can use the formula °C = (18°F - 32) ÷ 1.8, which gives you a result of -7.78°C.
