We are used to using temperature in everyday life: we measure the degrees of air to decide what clothes to wear, it is also important to know the temperature of food so as not to get burned or, conversely, not to freeze. But we are used to estimating everything in degrees Celsius, and there are other units for measuring temperatures, for example, Kelvin, degrees Reaumur, Hooke, Newton. And if the ones just named are used only in physics, then in Celsius and Fahrenheit we measure everything in ordinary life. In this article, we will understand why Fahrenheit is needed? How do I convert Fahrenheit to other temperature units?
Why use Fahrenheit?
Fahrenheit and Celsius are relative units of temperature. In Celsius, 0 ºC is the freezing point of water, and +100 ºC is the boiling point of water. A degree Fahrenheit is equal to 1.8 (9/5) degrees Celsius. The melting temperature of ice in Fahrenheit is +32 ºF. 1°F equals1/180 of the temperature difference between water boiling and ice melting at atmospheric pressure.
Which scale to use is a matter of habit. Fahrenheit is heavily used in the US and UK, and most of the world measures temperatures in Celsius.
In the US, Fahrenheit has been used almost since the formation of the state. Once the government wanted to introduce the use of Celsius as the world standard, and began to show the weather forecast in them, but the people did not understand and did not accept such drastic changes. A lot of complaints poured into the government, which is why they decided to leave everything as it is.
How to convert Fahrenheit to Celsius?
Many of us love to travel and the US and UK are very attractive countries. Arriving there, we will see Fahrenheit, which is unusual for us. So how do you convert Celsius degrees to Fahrenheit? The formula is quite difficult, not everyone can calculate in the mind, but it is worth remembering:
yºF=xºC9/5+32
For example, you need to convert 10 ºC to Fahrenheit. To begin with, we multiply 10 by 9/5, it turns out 90/5, which is 18. Then we add 32 to the resulting value and we get that 10 ºC=50 ºF.
If you need to convert from Fahrenheit to Celsius, then subtract 32 from Fahrenheit, and then multiply by 5/9.
For example: subtract 32 from 50 ºF, we get 18. 18 multiplied by 5 is 90. 90 divided by 9, we get 10 ºC.
How to convert Fahrenheit to Kelvin?
Kelvins are actively used inthermodynamics. Zero is the minimum temperature at which life is possible. 0 K=-273 ºC. First, let's figure out how to convert Kelvin to Celsius and vice versa. From the fact that 0 K=-273 ºC, it follows: x ºC=y K - 273.
We are given 300 Kelvin, which means it equals 27 ºC.
To get Kelvin from Celsius, you just need to add 273.
We have 10 ºC, add 273 so we get 283 K.
But how do you convert Fahrenheit to Kelvin? Everything is very simple. We know the conversion formula from Celsius to Fahrenheit and from Celsius to Kelvin. It turns out that you just need to substitute one formula into another:
yºF=(K-273)9/5+32
xK=yºF5/9+242
Let's calculate how to convert Fahrenheit to Kelvin. We have 50 ºF. Multiply by 5/9, we get 27.8. Add 242, equals 269.8 K.
It is worth noting that it is more correct not to use the phrase "Degrees Kelvin", it is better to use just "Kelvin".
Conclusion
