Fahrenheit to Celsius Formula, Examples | Convert F to C
Nevertheless where you are in the world, knowing the outside temperature is relevant to prepare for the day or having knowledge for a vacation. Within the three different units to calculate temperature, Celsius and Fahrenheit are typically most used. As a mathematical theory, it’s straightforward to observe the usefulness of converting from one to the other.
Let’s look at where these units come from and the equation to convert from Fahrenheit to Celsius. If you get this right, later when you travel, you can promptly convert these units without an online converter!
What Is Temperature?
The first matter to be aware about Fahrenheit and Celsius is that they are scales of measuring temps.
Temperature is the volume employed to calculate the hotness or coldness of things. It is measured with three main scales: Celsius, Fahrenheit, and Kelvin. The Celsius and Fahrenheit scales are used in majority parts of the world for daily life, whereas the Kelvin temp unit is more commonly employed in a scientific context.
The Fahrenheit and Celsius temps are distinct measures due to the fact they are based on the theories of distinct people.
The Celsius unit was invented by Anders Celsius, a Swedish scientist. He invented this scale with water, founding temp values in accordance to the freezing point and boiling point of water. He designated 100 degrees Celsius to indicate when water boils and 0 to the freezing point of water.
The Fahrenheit scale was created by Daniel Gabriel Fahrenheit, a German scientist. His scale was founded on brine's freezing and boiling point, that is salty water. He assigned the point when water freezes at 32, while the moment when it boils is 212 degrees Fahrenheit.
Majority of countries measure temperature in Celsius, but English-speaking countries, namely the United States and England, use the Fahrenheit temperature scale.
What Is the Formula for Converting Fahrenheit to Celsius?
Now that we understand more regarding the Fahrenheit and Celsius measures, let's focus on how the conversion within them works. As we saw previously, Celsius was created with the freezing and boiling temperatures of water being 0 and 100 degrees Celsius. These units are as same as 32 F for freezing and 212 F for boiling in Fahrenheit.
Formula to Convert to Celsius scale
Using water's properties, we can set a relationship with the temps in the Celsius and Fahrenheit scales. Bear in mind that the boiling point of water is when it reaches 100 degrees Celsius. We also understand that the boiling point of water in Fahrenheit is 212 degrees. From this, we can make the following equation:
100 Celsius = 212 Fahrenheit
We can solve this equation for Celsius and get the following equation:
Celsius = (Fahrenheit - 32) * (5/9)
This is the equation for conversion from Fahrenheit and Celsius. To utilize it, replace the temperature in Fahrenheit that you want to convert to Celsius.
Example
Let's make sure that this formula works as intended. Let’s solve for 212 F to C.
C = (212 F - 32) * (5/9)
C = 180 * 5/9
C = 100
As expected: 212 degrees F = 100 degrees C
How to Convert from Fahrenheit to Celsius
Now that we know the formula to convert Fahrenheit to Celsius, let's practice] it step-by-step.
Steps to convert Fahrenheit to Celsius
1) Primarily, take the temp in Fahrenheit that you want to convert, and deduct 32 from it.
2) Then, multiply that number by 5/9.
3) The ensuing value is the equivalent temperature in Celsius.
Example 1
We can moreover use the conversion formulas to understand the regular body temp from Fahrenheit to Celsius.
98.6 F to C
Replace this given temp into the Celsius formula:
C = (98.6 F - 32) * (5/9)
C = 66.6 * 5/9
C = 37
As we've just seen, a regular human body temperature is 98.6 degrees F, or its same in the Celsius scale, 37 degrees C.
Example 2
Let's use the Celsius conversion equation to transform a single degree Fahrenheit to Celsius. As normally, we will have to plug the numbers into the Celsius formula:
C = (1 F - 32) * (5/9)
By working out the entire formula, we will get the answer as a Celsius temp of:
C = (- 31) * (5/9)
C = -17.22
One degree Fahrenheit is even colder when you understand that it similar to -17.22 degrees Celsius!
