Fahrenheit to Celsius Formula, Examples | Convert F to C
Nevertheless where you are in the world, having knowledge of the outdoor temperature is relevant to prepare for the day or to pack for a vacation. Out of the three scales to measure temp, Fahrenheit and Celsius are typically most used. As a mathematical theory, it’s easy to see the usefulness of converting from one to the other.
Let’s take a look where these units come from and the equation to convert from Fahrenheit to Celsius. If you get this right, in future when you go for a trip, you can promptly convert these units without using a converter online!
What Is Temperature?
The primary matter to be aware about Celsius and Fahrenheit is that they are scales of metering temperatures.
Temperature is the volume utilized to measure the warmth or coldness of an object. It is calculated with three main units: Fahrenheit, Kelvin and Celsius. The Fahrenheit and Celsius scales are employed in majority parts of the world for routine life, while the Kelvin temp unit is more frequently employed in a scientific environment.
The Celsius and Fahrenheit temps are distinct scales as they are in accordance with the theories of different people.
The Celsius unit was founded by Anders Celsius, a Swedish scientist. He invented this scale with water, founding temp units 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 temp of water.
The Fahrenheit scale was invented by Daniel Gabriel Fahrenheit, a German physicist. His measurement was based on brine's freezing and boiling temp, that is salty water. He allocated the point when water freezes at 32, while the temp when it boils is 212 degrees Fahrenheit.
Majority of countries calculate temperature in Celsius, but English-speaking countries, namely England and the United States, use the Fahrenheit temperature scale.
What Is the Formula for Converting Fahrenheit to Celsius?
Now that we learned more about the Celsius and Fahrenheit measures, let's focus on how the conversion between them functions. As we observed previously, Celsius was created with the freezing and boiling points of water being 0 and 100 degrees Celsius. These measures 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 base a relationship with the temps in the Fahrenheit and Celsius units. Keep in mind that the boiling point of water is when it gets to 100 degrees Celsius. We also understand that the boiling point of water in Fahrenheit is 212 degrees. From here, we can create the following equation:
100 Celsius = 212 Fahrenheit
We can solve this formula for Celsius and achieve the following formula:
Celsius = (Fahrenheit - 32) * (5/9)
This is the equation for conversion from Fahrenheit and Celsius. To use it, substitute the temp in Fahrenheit that you want to convert to Celsius.
Example
Let's make sure that this formula functions. Let’s solve for 212 F to C.
C = (212 F - 32) * (5/9)
C = 180 * 5/9
C = 100
As intended we get: 212 degrees F = 100 degrees C
How to Convert from Fahrenheit to Celsius
Now that we learned the formula to convert Fahrenheit to Celsius, let's practice] it one-by-one.
Steps to convert Fahrenheit to Celsius
1) Primarily, take the temp in Fahrenheit that you have to convert, and deduct 32 from it.
2) Next, multiply that value by 5/9.
3) The resulting number is the equivalent temperature in Celsius.
Example 1
We can moreover use the conversion equations to learn the regular body temp from Fahrenheit to Celsius.
98.6 F to C
Plug this provided 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 equivalent in the Celsius unit, 37 degrees C.
Example 2
Let's use the Celsius conversion equation to transform a single degree Fahrenheit to Celsius. As normally, we would have to plug the value into the Celsius formula:
C = (1 F - 32) * (5/9)
By figuring out the entire formula, we will get the answer as a Celsius temperature of:
C = (- 31) * (5/9)
C = -17.22
One degree Fahrenheit seems even colder when you understand that it similar to -17.22 degrees Celsius!
