Temperature Converter Online

A temperature converter is a simple online tool that helps you change a temperature from one unit to another.

You may need to convert:

• Celsius to Fahrenheit
• Fahrenheit to Celsius
• Celsius to Kelvin
• Kelvin to Celsius
• Fahrenheit to Kelvin
• Kelvin to Fahrenheit

Temperature is part of everyday life. We use it when checking the weather, cooking food, traveling, studying, and working.

With Multiconverts, you can enter a temperature, choose the unit you have, choose the unit you want, and get the result quickly.

What Is Temperature?

Temperature tells us how hot or cold something is.

For example:

• Ice is cold.
• Boiling water is hot.
• A warm room has a higher temperature than a cold room.

We usually measure temperature using Celsius, Fahrenheit, or Kelvin.

The same temperature can have different numbers depending on the unit.

For example:

0°C = 32°F

The temperature is the same, but the number is different.

What Is a Temperature Converter?

A temperature converter changes a temperature from one scale to another.

For example, you may see the weather reported as:

86°F

If you normally use Celsius, you can convert it to:

30°C

The temperature has not changed. Only the way it is written has changed.

A temperature converter does the calculation for you.

Main Temperature Units

The three main temperature scales are:

• Celsius
• Fahrenheit
• Kelvin

Each scale has a different way of measuring temperature.

Celsius

Celsius is one of the most common temperature scales in the world.

It uses the symbol:

°C

Celsius is commonly used for:

• Weather
• Cooking
• Science
• Daily temperatures

Some important Celsius temperatures are:

0°C – Water freezes.

20°C – A mild room temperature.

37°C – About normal human body temperature.

100°C – Water boils at standard atmospheric pressure.

For example, if the weather is 30°C, it is usually considered hot.

Fahrenheit

Fahrenheit uses the symbol:

°F

It is commonly used for everyday temperatures in the United States.

Some useful examples are:

32°F = 0°C

68°F = 20°C

86°F = 30°C

98.6°F = 37°C

212°F = 100°C

If you travel between countries, you may need to convert Fahrenheit to Celsius or Celsius to Fahrenheit.

Kelvin

Kelvin is commonly used in science.

Its symbol is:

K

Unlike Celsius and Fahrenheit, Kelvin does not normally use the degree symbol.

For example:

0°C = 273.15 K

Kelvin is useful when working with scientific measurements and very low temperatures.

The Kelvin scale starts at absolute zero, which is 0 K.

Celsius to Fahrenheit

Celsius to Fahrenheit is one of the most common temperature conversions.

The formula is:

°F = (°C × 9/5) + 32

For example, let’s convert 20°C to Fahrenheit:

20 × 9/5 + 32 = 68°F

Therefore:

20°C = 68°F

Another example:

30°C = 86°F

This conversion is useful when reading weather information from the United States.

Fahrenheit to Celsius

To convert Fahrenheit to Celsius, use this formula:

°C = (°F − 32) × 5/9

For example:

68°F

First subtract 32:

68 − 32 = 36

Then multiply by 5/9:

36 × 5/9 = 20°C

Therefore:

68°F = 20°C

Celsius to Kelvin

To convert Celsius to Kelvin, add 273.15.

The formula is:

K = °C + 273.15

For example:

20°C + 273.15 = 293.15 K

Therefore:

20°C = 293.15 K

Kelvin to Celsius

To convert Kelvin to Celsius, subtract 273.15.

The formula is:

°C = K − 273.15

For example:

300 K − 273.15 = 26.85°C

Therefore:

300 K = 26.85°C

Fahrenheit to Kelvin

You can also convert Fahrenheit to Kelvin.

The formula is:

K = (°F − 32) × 5/9 + 273.15

For example:

68°F = 293.15 K

This conversion can be useful when working with scientific information.

Kelvin to Fahrenheit

To convert Kelvin to Fahrenheit, use:

°F = (K − 273.15) × 9/5 + 32

For example:

293.15 K = 68°F

Common Temperature Conversions

Here are some common temperature values:

Celsius	Fahrenheit	Kelvin
-40°C	-40°F	233.15 K
0°C	32°F	273.15 K
10°C	50°F	283.15 K
20°C	68°F	293.15 K
25°C	77°F	298.15 K
30°C	86°F	303.15 K
37°C	98.6°F	310.15 K
40°C	104°F	313.15 K
100°C	212°F	373.15 K

These examples can help you understand the relationship between the three temperature scales.

Why Do People Need a Temperature Converter?

A temperature converter can be useful in many everyday situations.

Weather

Weather websites may use Celsius or Fahrenheit.

For example, you may see:

95°F

If you normally use Celsius, you can convert it to:

35°C

This makes it easier to understand the weather.

Travel

Different countries may use different temperature scales.

A temperature converter can help you understand local weather during a trip.

Cooking

Recipes may use a different temperature unit from the one you normally use.

For example, an oven recipe may say:

400°F

You can convert it to Celsius:

400°F ≈ 204.44°C

This helps you set the correct oven temperature.

School

Students often work with Celsius, Fahrenheit, and Kelvin in math and science.

A temperature converter can help check calculations and understand the differences between the scales.

Science

Scientists commonly use Kelvin when working with temperature.

Celsius and Fahrenheit may also be used depending on the subject.

How to Use a Temperature Converter

Using an online temperature converter is easy.

Step 1: Enter the Temperature

Enter the number you want to convert.

For example:

25

Step 2: Select the Starting Unit

Choose the unit you currently have.

For example:

Celsius

Step 3: Select the Unit You Want

Choose the unit you need.

For example:

Fahrenheit

Step 4: Check the Result

The converter calculates the new temperature.

For example:

25°C = 77°F

You can then use the result for your recipe, travel plans, school work, or other needs.

Temperature Converter Examples

Example 1: Weather

The weather is 30°C.

You want to know the temperature in Fahrenheit.

30°C = 86°F

So the temperature is 86°F.

Example 2: Weather in the United States

The weather is 95°F.

You want to know the temperature in Celsius.

95°F ≈ 35°C

So the temperature is about 35°C.

Example 3: Cooking

A recipe says to set the oven to 350°F.

You want to know the temperature in Celsius.

350°F ≈ 176.67°C

So the oven temperature is about 177°C.

Example 4: Science

A scientific measurement is:

300 K

To convert it to Celsius:

300 − 273.15 = 26.85°C

So:

300 K = 26.85°C

Celsius vs Fahrenheit

Celsius and Fahrenheit use different numbers for the same temperature.

For example:

0°C = 32°F

10°C = 50°F

20°C = 68°F

30°C = 86°F

40°C = 104°F

This is why it is important to know which scale is being used.

A number by itself may not tell you how hot or cold something is.

For example:

30

could mean:

30°C

or:

30°F

These are very different temperatures.

Celsius vs Kelvin

Celsius and Kelvin have the same size between temperature steps, but their starting points are different.

For example:

0°C = 273.15 K

100°C = 373.15 K

To change Celsius to Kelvin, add 273.15.

To change Kelvin to Celsius, subtract 273.15.

Fahrenheit vs Celsius

Fahrenheit and Celsius use different scales.

For example:

32°F = 0°C

68°F = 20°C

86°F = 30°C

104°F = 40°C

The difference between the two scales is why a formula is needed for conversion.

Important Temperature Points

Some temperatures are useful to remember.

Water Freezing

At standard atmospheric pressure:

0°C = 32°F = 273.15 K

Water Boiling

At standard atmospheric pressure:

100°C = 212°F = 373.15 K

Human Body Temperature

A commonly used reference for normal human body temperature is approximately:

37°C = 98.6°F = 310.15 K

Actual body temperature can vary from person to person.
