Celsius and Fahrenheit are two important temperature scales. The Fahrenheit scale is used primarily in the United States, while Celsius is used throughout the world. The two scales have different zero points and the Celsius degree is bigger than the Fahrenheit.
However, there is one point on the Fahrenheit and Celsius scales where the temperatures in degrees are equal. This is -40 °C and -40 °F. If you can't remember the number, there is a simple algebraic method to find the answer.
Key Takeaways: When Does Fahrenheit Equal Celsius?
Celsius and Fahrenheit are two temperature scales.
The Fahrenheit and Celsius scales have one point at which they intersect. They are equal at -40 °C and -40 °F.
The simple method to find when two temperature scales are equal to each other is to set the conversion factors for the two scales equal to each other and solve for temperature.
Rather than converting one temperature to another (which is not helpful because it assumes you already know the answer), you can set degrees Celsius and degrees Fahrenheit equal to each other using the conversion formula between the two scales:
°F = (°C * 9/5) + 32 °C = (°F - 32) * 5/9
It does not matter which equation you use; simply use x instead of degrees Celsius and Fahrenheit. You can solve this problem by solving for x:
°C = 5/9 * (°F - 32) x = 5/9 * (x - 32) x = (5/9)x - 17.778 1x - (5/9)x = -17.778 0.444x = -17.778 x = -40 degrees Celsius or Fahrenheit
Working using the other equation, you get the same answer:
You can set two scales equal to each other to find when any of them intersect. Sometimes it's easier to just look up the equivalent temperature. This handy temperature conversion scale may help you out.
You can also practice converting between temperature scales:
The Celsius scale, also known as the centigrade scale, is a temperature scale based on 0o for the freezing point of water and 100o for the boiling point of water. This scale was first introduced by (and is named after) the Swedish physicist, astronomer, and engineer Anders Celsius.
, Celsius and Fahrenheit used in the world. There is a point on both scales where the temperatures in degrees
degrees
A degree can be defined as a set change in temperature measured against a given scale; for example, one degree Celsius is one-hundredth of the temperature change between the point at which water starts to change state from solid to liquid state and the point at which it starts to change from its liquid to gaseous state ...

The Fahrenheit and Celsius scales have one point at which they intersect. They are equal at -40 °C and -40 °F. The simple method to find when two temperature scales are equal to each other is to set the conversion factors for the two scales equal to each other and solve for temperature.
This means Celsius is 1.8 times larger than Fahrenheit. To put another way, 1 degree Fahrenheit is 5/9 degree Celsius. Despite the pretty large differences between one another, these two temperature scales intersect at -40 degrees, meaning that -40 degrees Fahrenheit is the same as -40 degrees Celsius.
Both scales have their own thermometer for measurements. Fahrenheit scale is proposed by taking 32 °F as a freezing point of water and 212 °F as a boiling point of water. Whereas in the Celsius scale 0 °C is the freezing point of water and 100 °C is the boiling point of water.
The relation between Celsius and Fahrenheit is proportional. Both have a different freezing point of water and both follow the varied unit difference between each scale.
For example, if we need to convert 40 degrees Fahrenheit to Celsius, we will substitute the value of Fahrenheit in the formula to get, °C = (40° - 32) × 5/9 = 4.4°C. This means, 40° F = 4.4°C.
What is the Formula to Convert Fahrenheit to Celsius? The Fahrenheit to Celsius formula is expressed as °C = (°F - 32) × 5/9; in which the value of F (Fahrenheit) is substituted and we get the value in Celsius. This formula converts the given temperature value from Fahrenheit to Celsius.
The Fahrenheit and Celsius scales converge at -40°. Ie, Temperature which shows the same measurement in Celsius and Fahrenheit= -40°. The formula used to convert Celsius(C) into Fahrenheit(F) is: F = 9 5 × C + 32.
Remember, Kelvin temperature is not expressed using degrees, just a capital letter K. This is basically the same as saying Kelvin equals the Celsius value plus 273.15. Remember to check your work. The only temperature where the Kelvin and Fahrenheit values will be equal is at 574.25.
