# Celsius To Kelvin Formula

Before learning the Celsius formula, let us recall what are Kelvin and Celsius. These are two different units of temperature. The Celsius scale was invented by Anders Celsius and the temperature in Celsius is represented in °C. Kelvin scale was invented by Lord Kelvin and the temperature in Kelvin is represented in K. Let's move ahead and check out the Celsius to Kelvin formula.

## What Is Celsius To Kelvin Formula?

The Celsius to Kelvin formula is used to change the unit of temperature from Celsius to Kelvin. There is actually nothing much that is complicated about this formula. The temperature can be converted from Celcius to Kelvin just by adding the number 273.15 to it. Here is the Celsius to Kelvin formula.

### Celsius To Kelvin Formula

The Celcius to Kelvin formula is,

T (K) = T (°C) + 273.15

where,

- T(°C) = Temperature in Celsius
- T (K) = Temperature in Kelvin

## Celsius To Kelvin Formula Derivation

Let us observe the freezing point and the boiling point of water in both Celsius and Kelvin scales.

Celsius Scale | Kelvin Scale | |
---|---|---|

Freezing point |
0°C | 273.15 K |

Boiling point |
100°C | 373.15 K |

If we observe, each temperature in the Kelvin scale is exactly 273.15 more than the corresponding temperature in the Celsius scale. Thus, the temperature in Kelvin is obtained by adding 273.15 to the corresponding temperature in the Celsius scale. Thus, if T(°C) is the temperature in Celsius and T (K) is the temperature in Kelvin then the Celsius to Kelvin formula is,

T (K) = T (°C) + 273.15

## Examples Using Celsius To Kelvin Formula

**Example 1: **Convert 15°C into Kelvin.

**Solution: **

T(°C) = 15°C (Given)

T(K) =?

By using the Celsius to Kelvin formula,

T (K) = T (°C) + 273.15

T (K) = 15 + 273.15 = 288.15 K

**Answer:** 15°C = 288.15 K.

**Example 2: **We know that the boiling point of water is 100°C. Can you convert it into Kelvin?

**Solution: **

T(°C) = 100°C (Given)

T(K) = ?

By using the Celsius to Kelvin formula,

T (K) = T (°C) + 273.15

T (k) = 100 + 273.15 = 373.15 K

**Answer: **The boiling point of water (100°C) = 373.15 K.

**Example 3: **If the temperature of a pizza that is in the oven is 520 K, then what is its temperature in Celsius?

**Solution:**

T (K) = 520 K (Given)

T(°C) = ?

By using the Celsius to Kelvin formula,

T (K) = T (°C) + 273.15

520 = T (°C) + 273.15

Subtracting 273.15 from both sides,

T (°C) = 246.85

**Answer: **The temperature of pizza in Celsius is 246.85°C.

## FAQs on Celsius To Kelvin Formula

### What Is Celsius To Kelvin Formula?

The Celsius to Kelvin Formula is used to convert the temperature from Celsius to Kelvin. This formula says T (K) = T (°C) + 273.15 where T(°C) is the temperature in Celsius and T (K) is the temperature in the Kelvin.

### How To Derive the Celsius To Kelvin Formula?

If we observe any temperature in terms of Celsius and Kelvin (for example, the boiling point of water in Celsius and Kelvin is 100°C and 373.15 K respectively), the temperature in Celsius is obtained by adding 273.15 to the temperature in Kelvin. Thus, the Celsius to Kelvin formula is, T (K) = T (°C) + 273.15 where

- T(°C) is the temperature in Celsius
- T (K) is the temperature in Kelvin

### What Are the Applications of Celsius To Kelvin Formula?

The Celsius to Kelvin formula, as its name suggests, is used to convert the temperature in Celsius to the temperature in Kelvin. Thus, it is widely used in the fields of Math, Physics, and Chemistry.

### What Is Zero Degree Celsius in Kelvin Using Celsius To Kelvin Formula?

According to the Celsius to Kelvin formula, by adding 273.15, the temperature in Celsius can be converted to the temperature in Kelvin. Thus, 0°C = 0 + 273.15 = 273.15 K.
