How to Convert Temperature: Easy Methods for Fahrenheit, Celsius & Kelvin

Knowing how to convert temperature can be a pretty useful when dealing with recipes or weather reports in different units. In this article, we’ll look at the basics of temperature conversion, introduce various units of temperature and highlight the key formulas you need to switch between them.

How to Convert Temperature

Are you trying to figure out how to convert temperature measurements between Celsius, Fahrenheit, and Kelvin? No worries, you’ve come to the right place. We’re going to keep this pretty simple, so let’s dive right in.

With temperature conversion, it’s just a matter of using the right formulas.

Below are the three essential formulas you’ll need:

1. Celsius to Fahrenheit: F = C × 9/5 + 32
2. Fahrenheit to Celsius: C = (F – 32) × 5/9
3. Celsius to Kelvin: K = C + 273.15

Now, let’s say you have a temperature reading of 25°C and want to convert it to Fahrenheit.

To do this, simply follow the first formula:

F = 25 × 9/5 + 32 ≈ 77°F (Celsius to Fahrenheit)

Easy, right? The same goes for converting Fahrenheit to Celsius. Here’s an example to convert 68°F to Celsius:

C = (68 – 32) × 5/9 ≈ 20°C (Fahrenheit to Celsius)

Converting between Celsius and Kelvin is also a breeze. To convert 20°C into Kelvin:

K = 20 + 273.15 = 293.15 K

And there you have it!

These three formulas will ensure that you never get puzzled by temperature conversions again.

Once you’ve got these formulas nailed down, temperature conversions will be an absolute breeze.

Units of Temperature

You might wonder, “What are the different units of temperature, and how do I convert them?”

Let’s go through them all step by step, and, hopefully, by the end, you’ll be able to convert temperatures like a proper pro!

Celsius

First up is the Celsius scale.

The Celsius scale, named after Anders Celsius, who introduced it way back in 1742. This is probably the most common temperature unit around the world. It’s probably the one we are also most familiar with – think of your kettle and you’ll probably think of it boiling your water to a 100°C.

The freezing point of water in this scale is at 0°C (zero degrees Celsius), and the boiling point is at 100°C.

Converting Celsius to the other two units is straightforward, and here’s the formula to help you out:

• To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32
• To convert Celsius to Kelvin: K = °C + 273.15

Fahrenheit

Now, let’s move on to Fahrenheit.

This unit, named after Daniel Gabriel Fahrenheit, is more commonly used in the United States.

On this scale, the freezing point of water is at 32°F (thirty-two degrees Fahrenheit), while the boiling point is at 212°F.

Converting Fahrenheit to the other temperature units can be done using these formulas:

• To convert Fahrenheit to Celsius: °C = (°F - 32) × 5/9
• To convert Fahrenheit to Kelvin: K = (°F + 459.67) × 5/9

Kelvin

And last, but not least, we have the Kelvin scale, which is primarily used in scientific research. It’s named after Lord Kelvin, who introduced it in 1848.

This unit is unique because it begins at absolute zero (0 K), the lowest possible temperature where all molecular motion stops.

Unlike the other two units, Kelvin doesn’t use “degrees” before its symbol, just “K.” When you want to convert temperatures to and from Kelvin, use these formulas:

• To convert Kelvin to Celsius: °C = K - 273.15
• To convert Kelvin to Fahrenheit: °F = (K × 9/5) - 459.67

So there you have it! Now you’re familiar with the three most common temperature units and how to convert them.

How to Convert Celsius to Fahrenheit

The easy way to convert Celsius to Fahrenheit is by using a (relatively) simple formula.

To convert any temperature in Celsius to Fahrenheit, this is the formula to use:

Fahrenheit = (Celsius × 9/5) + 32

Let’s break it down. Here’s what you need to do:

1. Multiply the Celsius temperature by 9/5: This is the conversion factor that relates the two temperature scales.
2. Add 32: Why 32? That’s because the freezing point of water in Fahrenheit is at 32°F, while in Celsius, it’s at 0°C.

Now, let’s put it into practice! Say you want to convert 25°C to Fahrenheit. Here’s the step-by-step process:

1. Multiply 25 by 9/5: (25 × 9/5) = 45
2. Add 32 to the result: 45 + 32 = 77

Voilà! 25°C is equal to 77°F.

How to Convert Fahrenheit to Celsius

Converting temperatures between these two common scales is actually a piece of cake.

Let’s dive right in and learn how to do it together.

The formula for converting Fahrenheit to Celsius is also pretty straightforward:

Celsius = (Fahrenheit - 32) × 5/9

Now, let’s break it down step by step.

1. Subtract 32: Start by taking the Fahrenheit temperature and subtracting 32. This will help account for the difference at the starting point of each scale (0°C = 32°F).
2. Multiply by 5/9: Next, multiply the result from the previous step by 5/9. This part of the formula is essential because it scales the difference in temperature according to the relation between the two units (1°C = 9/5°F).

Alright, let’s put this formula to the test! Say you want to convert 68°F into Celsius. Here’s how it works:

1. Subtract 32 from the Fahrenheit temperature: 68 - 32 = 36
2. Multiply the result by 5/9: 36 × 5/9 ≈ 20

68°F is approximately 20°C. Easy-peasy, right?

To make this process even easier, you can use this handy little table to look up common Fahrenheit-to-Celsius conversions quickly.

Now that you’ve got the hang of it, you should be able to convert any Fahrenheit temperature to Celsius. So next time you’re talking to your international friends about the weather, you’ll be able to switch smoothly between temperature scales. 😉

How to Convert Celsius to Kelvin

The formula to convert Celsius to Kelvin is possibly the simplest in this article:

K = C + 273.15

Here, K represents the temperature in Kelvin and C denotes the temperature in Celsius.

Just add 273.15 to your Celsius temperature, and voilà, you have the Kelvin equivalent!

Let’s look at an example – imagine you want to convert 25°C (a fairly warm day) to Kelvin. Using the formula above, you’ll find the temperature to be:

K = 25 + 273.15 = 298.15 K

3. Your celsius temperature 25 + 273.15 = 298.15 k (the Kelvin temperature equivalent)

How to Convert Kelvin to Celsius

The formula used to convert Kelvin to Celsius is:

Celsius = Kelvin - 273.15

As you might have noticed, it’s the opposite of the formula that we use to convert Celsius to Kelvin.

Now, all that’s required is plugging in the Kelvin temperature and we can convert it by doing some simple subtraction. Subtract 273.15 from the Kelvin temperature, and you’ll have your answer in Celsius.

If you have a temperature of 300 Kelvin. To convert it to Celsius, just follow the formula:

Celsius = 300 - 273.15

Celsius ≈ 26.85

And there you have it! 300 Kelvin is approximately 26.85 degrees Celsius.
