**1 K in Celsius = -272.15°C, the kelvin to celsius converter enables seamless calculation between the Kelvin scale in Celsius scale with °C = K – 273.15 formula. **

The Kelvin scale, established by **Lord William Thomson Kelvin**, represents the **absolute temperature scale** used extensively in **scientific measurements** and calculations. This scale begins at **absolute zero** (-273.15°C), making it particularly valuable for scientific applications where negative temperatures are impractical.

When working with

thermodynamic calculationsin chemistry, a temperature of350 Kelvinneeds to be converted to Celsius for practical understanding. Usingkelvin to celsius calculation, we can quickly determine that350K equals 76.85°C.

## Kelvin to Celsius Conversion Formula

The conversion between **Kelvin in Celsius** is expressed through a **simple subtraction formula**:

**°C = K - 273.15**

Where:

- °C represents the temperature in Celsius
- K represents the temperature in Kelvin
**273.15**is the constant difference between the scales

Consider converting **400 Kelvin** to Celsius:

```
°C = 400 - 273.15
°C = 126.85°C
```

## How to Convert Kelvin to Celsius?

**Converting degree kelvin to celsius involves three-step process:**

**Identify** the temperature in Kelvin

**Subtract** 273.15 from the Kelvin value

**Express** the result in degrees Celsius (°C)

To convert **298 Kelvin** to Celsius:

**°C = 298 - 273.15
°C = 24.85°C**

**0 Kelvin**=**-273.15°C**(Absolute zero)**1 Kelvin**=**-272.15°C****10 Kelvin**=**-263.15°C****50 Kelvin**=**-223.15°C****100 Kelvin**=**-173.15°C****273 Kelvin**=**-0.15°C****273.15 Kelvin**=**0°C**(Water freezing point)**350 Kelvin**=**76.85°C****351 Kelvin**=**78.85°C****373 Kelvin**=**100°C**(Water boiling point)

To convert 300 K to Celsius:

- Temperature in Kelvin = 300 K
- 300 – 273.15 = 26.85
- Therefore, 300 K = 26.85°C

## What is the Formula for 273 Kelvin to Celsius?

The conversion of **273 Kelvin** follows the standard formula:

**°C = 273 - 273.15
°C = -0.15°C**

This calculation is slight difference between **273K** and the commonly referenced **273.15K**, which equals **0°C**.

This calculation shows that 273 K is slightly below the freezing point of water, which occurs at 273.15 K (0°C).

## Is 273 Kelvin the Same as 0 Degrees Celsius?

No, **273 Kelvin** is not exactly equal to **0 degrees Celsius**. The precise equivalent of **0°C is 273.15K**. This small difference of **0.15 degrees** is crucial in scientific calculations where precision is essential. For example:

**273K = -0.15°C
273.15K = 0°C**

## Is 1K Equal to 1°C?

No, **a one-unit change in Kelvin is not equivalent to a one-degree** change in Celsius in absolute terms.

The **size of one unit** is the same in both scales (a one-degree change in Celsius equals a one-Kelvin change), their starting points differ by 273.15 units. This means:

- A change of 1 K = A change of 1°C
- But: 1 K ≠ 1°C in absolute temperature

## Kelvin to Celsius Example Problems

**Room Temperature**:

293.15K to °C

°C = 293.15 – 273.15 =

20°C

**Water Boiling Point**:

373.15K to °C

°C = 373.15 – 273.15 =

100°C

**Water Freezing Point**:

273.15K to °C

°C = 273.15 – 273.15 =

0°C
