The answer is: 209.44 degrees Celsius or 209.44° C
Let's look into the conversion between Fahrenheit and Celsius scales in detail.
Calculate 409° Fahrenheit to Celsius (409F to °C)
The answer to 409°F to C. This calculator will help you know how hot or cold 409F is in Celcius. The F to C formula is (F − 32) × 5/9.
Temperatures, across the world, are measured either in Fahrenheit(the US temperature scale) or Celsius(the metric scale), two of the most popular and widely used scales.
Temperature Conversion - Degrees Fahrenheit into Degrees Celsius
Fahrenheit to celsius conversion formula is all about converting the temperature denoting in Fahrenheit to Celsius. As mentioned earlier, the temperature of boiling (hot) water in Celsius is 0 degrees and in Fahrenheit is 21 degrees, the formula to convert F to C is
°C = (°F − 32) x 5/9
The math is here is fairly simple, and can be easily understood by an example. Let's say we need to 409 Fahrenheit to Celsius
How To Convert 409 F to C?
To convert 409 degrees Fahrenheit to Celsius, all one needs is to put in the values in the converter equation-
°C = (°F − 32) x 5/9
C = 209.44 degrees
Thus, after applying the formula to convert 409 Fahrenheit to Celsius, the answer is -
409°F = 209.44°C
409 degrees Fahrenheit equals 209.44 degrees Celsius!

How to Convert From Fahrenheit to Celsius and Celsius to Fahrenheit - Quick and Easy Method
What is the formula to calculate Fahrenheit to Celsius?
The F to C formula is
(F − 32) × 5/9 = C
When we enter 409 for F in the formula, we get
(409 − 32) × 5/9 = 209.44 C
To be able to solve the (409 − 32) × 5/9 equation, we first subtract 32 from 409, then we multiply the difference by 5, and then finally we divide the product by 9 to get the answer in Celsius.
What is the simplest way of converting Fahrenheit into Celsius?
The boiling temperature of water in Fahrenheit is 21 and 0 in Celsius. So, the simplest formula to calculate the difference is
C = (F − 32) × 5/9
For converting Fahrenheit into Celsius, you can use this formula – Fahrenheit Temperature – 32/ 2 = Celsius Temperature.
But this is not the only formula that is used for the conversion as some people believe it doesn’t give out the exact number.
One another formula that is believed to be equally easy and quick is
(°F - 32) x .5556
While there are other temperature units like Kelvin, Réaumur, and Rankine as well, Degree Celsius and Degree Fahrenheit are the most commonly used.
While Fahrenheit is primarily used in the US and its territories, Celsius has gained more popularity in the rest of the world. For those using these two different scales, the numbers that denote that temperature are quite different.
For example, water freezes at Zero Degree Celsius and boils at 100 degrees, the readings are 32-degree Fahrenheit as the freezing point of water and 212 degrees for boiling.
For Celsius Conversions
For Celsius conversion, all you need to do is start with the temperature in Celsius. Subtract 30 from the resultant figure, and finally, divide your answer by 2!

History of The Two Most Popular Temperature Units
The Fahrenheit temperature scale is named after the German physicist Daniel Gabriel Fahrenheit in 1724 and was originally used for temperature measurement through mercury thermometers that he invented himself.
Meanwhile, the Celsius scale was originally called centigrade but later came to be named after Swedish astronomer Anders Celsius in 1742. But when the scale was first introduced, it was quite the reverse of what it is today. Anders labeled 0 Degree Celsius as the boiling point of water, while 100 denoted the freezing point.
However, after Celsius passed away, Swedish taxonomist Carl Linnaeus flipped it to the opposite, the same as it is used today.
While this is the formula that is used for the conversion from Fahrenheit to Celsius, there are few diversions and it is not always a perfect conversion either making it slightly more difficult than what appears to be.
All said and done, one must understand that since both the scales are offset, meaning that neither of them is defined as starting from zero, there comes a slightly complicated angle to the above-mentioned formula.
Besides, the two scales do not start with a zero, and they both add a different additional value for every unit of heat. This is why it is not every time possible to get an exact value of the conversion by applying the formula.
