# Celsius Converter

The Celsius converter helps you convert from the Celsius scale (or the Centigrade scale) to any other temperature scale such as Kelvin, Fahrenheit, and so on. You could also do the reverse, i.e, convert from any of the temperature scales to find the equivalent temperature in the Celsius scale.

Read on to learn more about what the Celsius scale is and the formulas governing the conversion between the Celsius scale and other units of temperature.

## What is the Celsius scale?

The Celsius scale, invented in 1742 by the Swedish astronomer **Anders Celsius**, is based on the freezing and boiling points of water. The **freezing point of water** is set as **0° C**, and the **boiling point of water is set as 100° C**. The range of temperature values between these two bounds is divided into 100 degrees, thus giving it the alternative name, **centigrade scale**.

## Conversion between Celsius and other temperature scales

The conversion between the Celsius scale and other units of temperature is fairly straightforward and is governed by simple mathematical formulae, as shown below:

*Note:* Here, `T(°C)`

denotes the **temperature in degrees Celsius**, `T(°F)`

denotes the **temperature in Fahrenheit**, and so on.

**Degrees Celsius to Kelvin**

$T(K)\ =\ T(°C)\ +\ 273.15$

**Degrees Celsius to degrees Fahrenheit**

$T(°F)\ =\ \frac{9\ ×\ T(°C)}{5}\ +\ 32$

**Degrees Celsius to degrees Rankine**

$T(°R)\ =\ \frac{9\ ×\ T(°C)}{5}\ +\ 491.67$

**Degrees Celsius to degrees Delisle**

$T(°De)\ =\ -1.5\ ×\ T(°C)\ +\ 150$

**Degrees Celsius to degrees Newton**

$T(°N)\ =\ 0.33\ ×\ T(°C)$

**Degrees Celsius to degrees Réaumur**

$T(°Ré)\ =\ 0.8\ ×\ T(°C)$

**Degrees Celsius to degrees Rømer**

$T(°Rø)\ =\ 0.525\ ×\ T(°C)\ +\ 7.5$

## How do I use the Celsius converter?

To use the Celsius converter, you need to do the following:

- Enter the temperature in Celsius scale.
*Tada!*You will directly get the equivalent temperatures in other units!- Alternatively, you can also enter the temperature in other units, and get the equivalent temperature in degrees Celsius!

You can convert between the Celsius scale and any of the following scales of temperature:

- Kelvin scale;
- Fahrenheit scale;
- Rankine scale;
- Delisle scale;
- Newton scale;
- Réaumur scale; and
- Rømer scale.

## FAQ

### How do I convert from Celsius to Fahrenheit?

To convert the temperature from Celsius to Fahrenheit, do the following:

**Multiply**the Celsius temperature**by the fraction**.`9/5`

**Add 32**to the resulting number.*Voila!*You'll get the equivalent temperature in the**Fahrenheit scale**!

### What is 100° C in the Kelvin scale?

100° C is equivalent to **373 K** in the Kelvin scale. You can convert from the **Celsius scale to the Kelvin scale** by simply **adding 273** to the Celsius temperature!
