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 Celsius into Degrees Fahrenheit
Celsius to Fahrenheit conversion formula is all about converting the temperature denoting in Celsius to Fahrenheit. As mentioned earlier, the temperature of boiling (hot) water in Celsius is 0 degrees and in Fahrenheit is 21 degrees, the formula to convert C to F is
F = C x (9/5) + 32
The math is here is fairly simple, and can be easily understood by an example. Let’s say we need to 81 Celsius to Fahrenheit!
How To Convert 81 C to F?
To convert 81 degrees Celsius to Fahrenheit, all one needs is to put in the values in the converter equation-
F = 81 x (9/5) +32
F = 177.8 degrees
Thus, after applying the formula to convert 81 Celcius to Fahrenheit, the answer is –
81°C = 177.8°F
81 degrees Celsius equals 177.8 degrees Fahrenheit!
Frequently asked questions about converting 81 Degrees Celsius into Degrees Fahrenheit
How much is 81 degrees in Celsius to Fahrenheit?
81C to F = 177.8 °F
What is the formula to calculate Celsius to Fahrenheit?
The C to F formula is
(C × 9/5) + 32 = F
When we enter 81 for C in the formula, we get
(81 × 9/5) + 32 = 177.8 F
To solve (81 × 9/5) + 32 = F, we first multiply 9 by 81, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.
What is the simplest way of converting Celsius into Fahrenheit?
The boiling temperature of water in Celsius is 0 and 21 in Fahrenheit. So, the simplest formula to calculate the difference is
F = C X (9/5) + 32
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 –
Celsius Temperature X 2 + 32 = Fahrenheit
For converting Fahrenheit into Celsius, you can use this formula – Fahrenheit Temperature – 30 / 2 = Celsius Temperature.
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 is 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 Fahrenheit conversion, all you need to do is start with the temperature in Fahrenheit. Subtract 30 from the resultant figure, and finally, divide your answer by 2!

How to Convert From Fahrenheit to Celsius and Celsius to Fahrenheit - Quick and Easy Method
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 Celsius to Fahrenheit, 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.
