How do we convert -13 Celsius to Fahrenheit?
It can be very useful to know it, especially if we use Fahrenheit in every day life and then we go somewhere where Celsius are used the most.
So, the formula for conversion from Celsius to Fahrenheit is:
Fahrenheit (°F) = (Celsius * 1.8) + 32
Step by step explanation how to calculate this conversion
1. You have the temperature given in Celsius and you want to get it in Fahrenheit. First thing that you do is multiply that temperature in Celsius with 1.8.
If you don’t have a calculator or you are in some test where you aren’t allowed to use it, sometimes it may be easier to work with fraction instead of this decimal number. You can then instead multiply the temperature in Celsius you have with 9/5 (which is of course equal to 1.8). This may be useful if the temperature is a number that can be divided by 5 easily, so then we don’t have decimal points or fractions, we just lose the 5 from the denominator and divide the temperature with 5.
So it is clearer, this is the situation:
Temperature in Celsius is -13 °C.
First way would be to multiply it with 1.8.
The other way would be to multiply it with 9/5.
Then it would be -13 * (9/5) = -23.4.
This other way was in this particular case a lot easier, we didn’t need a calculator and it can be even done in the head if we are just converting some temperature while talking or doing something else, where we don’t have a pen and piece of paper or calculator.
2. Next, we add 32 to the number we got, that is -23.4 + 32 = 8.6 °F. It’s simple and there is no other explanation needed. When we do it, we got the temperature in Fahrenheit that we were looking for!
It’s less common, but there is one more formula that people use to convert Celsius to Fahrenheit:
Step by step it would go like this:
1. We add 40 to the temperature in Celsius.
2. Then we multiply the number we got with 1.8. Again, like in the first way of converting Celsius to Fahrenheit if it is easier to calculate we can multiply with 9/5 (because it is equal to 1.8).
3. And in the end we subtract 40 from the number we got. Then we get our temperature in Fahrenheit!
Before we only showed when it is easier and more practical to use fraction than decimal number, but now let’s see how we could do one full example:
Let’s have the temperature in Celsius that is -13 °C. How many Fahrenheit is it?
First way to convert Celsius to Fahrenheit:
- -13 * 1.8 = -23.4
- -23.4 + 32 = 8.6
Second way to convert Celsius to Fahrenheit:
- -13 + 40 = 27
- 27 * 1.8 = 48.6
- 48.6 - 40 = 8.6
We see that we got the same result, which was expected. As always, different ways to calculate something shouldn’t change the result. This can also be a good way to double-check if you converted it correctly, if it turns out to be the same number in both ways, it should be right.
Q&As on converting -13 degrees Celsius to Fahrenheit
Q. Which temperature is colder -13 °F or -13 °C?
A. The temperature in degrees Fahrenheit is colder, so -13 °F is colder than -13 °C.
Q. Which temperature is warmer -13 °F or -13 °C?
A. The temperature in degrees Celsius is warmer, so -13 °C is warmer than -13 °F.
Q. What is -13 degrees C equal to in Fahrenheit?
A. -13 degrees C equal to 8.6 degrees in Fahrenheit.
Let’s go through some other questions that may come to our mind when thinking about this:
Q. Is Celsius and Fahrenheit useful to know?
A. Let’s just imagine the next situation. You live in the US and normally, every day you use Fahrenheit as temperature unit. For example, when it is really cold outside, it is around 30 degrees Fahrenheit. When it is very warm outside, it is around 80 degrees Fahrenheit. Then you want to go on a vacation somewhere in Europe and want to know what kind of clothes to bring, but there is only local forecast, which is in Celsius. You see that it will be around 30 degrees Celsius when you go. If you didn’t know how to convert it, you may end up bringing sweaters and all the other warm clothes, when you would actually need shorts and T-shirts.
Q. Why can’t we just add 32 to temperature in Celsius and get temperature in Fahrenheit?
A. It would be nice and a lot easier. This is a very common question, but it’s not possible in any way. If that would be true, that would mean that the scales just have different starting point, that the divisions on both scales are the same.
For a moment, let’s assume that this is true. That would mean that between the same temperatures like boiling and freezing of water, the difference would be the same without consideration of the scale. Let’s check if it is true.
On Celsius scale: 100 - 0 = 100
On Fahrenheit scale: 212 - 32 = 180
That shows us that 180 divisions on Fahrenheit scale are equal to 100 divisions on Celsius scale meaning that we can’t just simply add 32. We have to scale it somehow to get to another scale. From here we can also see why we are multiplying with 1.8 (180/100=1.8).
Q. Are there any tips and tricks that could help us convert these units faster?
A. As we mentioned a couple of times, it can be difficult to do calculations for this conversion, because these numbers are not whole and there can appear mistakes. There isn’t any magical trick that could help you calculate this easy, but there are some tricks that could help you:
One of them is what we mentioned in the step by step conversion: if the temperature can be divided by 5, to use the fraction instead of decimal number.
Also, if you are just trying to convert temperatures approximately, like in the example we had before, to see what kind of clothes to wear, you can use an approximation. Instead of multiplying with 1.8, you can use 2 and then your calculations will be much easier..
IMPORTANT: You can’t use this method when you want to get a precise conversion, you use it just when you need to get an idea of temperature. If you are doing any scientific calculation or doing any work for school or test, you have to use the precise formula with 1.8.
By practice and with time, this becomes natural and you don’t even have to think “What is the formula for conversion…”, it just comes to your mind without much thinking.
What is Celsius (°C) and Fahrenheit (°F)?
Celsius (°C) and Fahrenheit (°F) are one of the units used to describe temperature. There is also one more unit that is used for temperature, which is Kelvin (K).
Someone may wonder why there are so many units and which one to use. There are no differences between these units, they are all used to describe same thing and which one you will use depends of the country you are in or if you are using it in every day situation or scientific calculation. Common similar example are units of length: meters and feet. If you are in Europe, you will use meters and if you are in US, you will use feet. So, in this particular case here is how the things are:
- If you need to include temperature in some scientific calculation, you are most likely going to use Kelvin
- If you are in US, you will use Fahrenheit
- If you are in Europe, you will use Celsius
Weird fact is that Celsius is SI unit for temperature, but in scientific calculations, we use Kelvin. It’s because it’s easier for calculations, but it still sounds weird.
Which is better: Celsius or Fahrenheit?
If you check some forum, you can find a lot of people arguing about which unit is better to use. As we said in the beginning, it really matters only from where you are based. The argument that both sides have is that the scale they are using represents the temperatures in a way that it’s easier for people to understand if it is cold or hot and at what degree.
But it is more about what we are used to, if we are used to from the childhood that the temperature of 30 degrees means that we should wear as many layers as possible (if we are in Fahrenheit), then it will be natural to us that those values represent cold weather. But also, the other person that wants to visit the pool as soon ad it is 30 degrees (if we are in Celsius) could never see that as a good way of showing that it is cold outside.
Conclusion: It depends on perspective and there is none significant distinction between these units.
Some common mistakes on Celsius & Fahrenheit
