## What is the Kelvin scale?

The **Kelvin scale**, developed by William Thomson (also known as Lord Kelvin) in the 18th century, is an **absolute temperature scale**, which uses **absolute 0 as its null point**. Meaning, there are no colder temperatures than 0 kelvin. Unlike other temperature units, kelvin doesn't come with the `degree (°)`

symbol. So we only use its abbreviation `K`

to define a value in kelvin.

Another unique thing about kelvin as a temperature unit is that we can express kelvins in the International System of Units (SI) multiples using **metric prefixes**. That is, we can say that **one kilokelvin (kK) is equal to 1000 kelvins (K)**, or **one millikelvin (mK) is equal to 0.001 kelvin**.

## Kelvin conversion formulas

Converting temperature values from kelvin to other temperature units such as degrees Celsius or degrees Fahrenheit only requires some basic mathematical operations like multiplication and addition or subtraction. Here are the different formulas for converting kelvin to other units where `T(K)`

is the **temperature in kelvin**, `T(°C)`

is a **temperature in degrees Celsius**, etc.:

__Kelvin to degrees Celsius__

`T(°C) = T(K) - 273.15`

__Kelvin to degrees Fahrenheit__

`T(°F) = 1.8 × T(K) - 459.67`

__Kelvin to degrees Rankine__

`T(°R) = 1.8 × T(K)`

__Kelvin to degrees Delisle__

`T(°De) = -1.5 × T(K) + 559.725`

__Kelvin to degrees Newton__

`T(°N) = 0.33 × T(K) - 90.1395`

__Kelvin to degrees Réaumur__

`T(°Ré) = 0.8 × T(K) - 218.52`

__Kelvin to degrees Rømer__

`T(°Rø) = 0.525 × T(K) - 135.90375`

## How to use our kelvin converter

To use our kelvin calculator, all you have to do is **enter a value in the Kelvin scale** to instantly show its corresponding equivalent values in other units of temperature.

You can also enter temperature values in, let's say, degrees Celsius or degrees Rankine to find its equivalent value in the Kelvin scale.

As an added feature, you can use the temperature in the Kelvin field at the end of the tool to display another temperature variable in the Kelvin scale. You can use this feature to **explore the entire SI multiples of the Kelvin scale** so you can also convert temperatures in kelvin to, say, gigakelvin or picokelvin.

### What is 500 kelvins in Fahrenheit?

**500 kelvins is equal to 440.33°F**. To determine the equivalent temperature value of 500 kelvins in degrees Fahrenheit, we first have to:

- Multiply the temperature in kelvins by 1.8:
**500 kelvins × 1.8 = 900**. - Then, we subtract 459.67 from the calculated value:
**900 - 459.67 = 440.33**. - Finally, attach the
**degree unit**,**°**, and the**Fahrenheit unit modifier**,**F**, to get**440.33°F**.

### How do I convert kelvin to Celsius?

You can use this equation to convert kelvin to degrees Celsius: **kelvin temperature = degrees Celsius temperature + 273.15**. So let's say we want to convert a room temperature of 20°C to kelvin. We can calculate it by substituting these values to our equation such that **kelvin temperature = 20°C + 273.15** = **293.15°C**

### What is the boiling point of water in kelvins?

The boiling point of water is **373.15 K**. We can get that value by converting the boiling point of water from 100 degrees Celsius to kelvin. To convert 100 degrees Celsius to kelvin, we add 273.15 to it to get 373.15 kelvins.
