When we convert temperatures from Kelvin to Celsius, we find that 293 Kelvin is equal to 19.85 degrees Celsius, and 470 Kelvin is equal to 196.85 degrees Celsius.

The Kelvin scale and the Celsius scale are two different ways to measure temperature. Kelvin is commonly used in scientific and technical contexts, while Celsius is more commonly used in everyday life. To convert the above temperatures one must use the formula mentioned below.

°C = K – 273.15

Where,

°C = denotes temperature in Celsius

K = denotes temperature in Kelvin

## What is Celsius?

Celsius is a unit of temperature measurement in the metric system. It is named after the Swedish astronomer Anders Celsius, who proposed the Celsius scale in 1742.

## Conversion Of Temperatures From Kelvin To Celsius

To convert a temperature from Kelvin to Celsius, you need to subtract 273.15 from the given temperature in Kelvin. This is because the Kelvin scale starts at absolute zero, which is the point where there is no heat energy, and it is equivalent to -273.15 degrees Celsius.

So, by subtracting 273.15, we can align the two scales. Positive temperatures in Kelvin will correspond to positive temperatures in Celsius, and the numerical values will be reduced by 273.15 units.

For example: let’s say we have a temperature of 293 Kelvin (293 K). To convert it to Celsius, we subtract 273.15 from it:

°C = 293 – 273.15

°C = 19.85

So, 293 Kelvin is equal to 19.85 degrees Celsius.

Solution

To convert temperatures from Kelvin (K) to Celsius (°C), you can use the formula:

°C = K – 273.15

## Convert 293 K to Celsius Scale

To convert 293 K to Celsius Scale,

Let’s apply this formula to the given temperature

°C = K – 273.15

°C = 293 – 273.15

°C = 19.85

Therefore, 293 K is equal to 19.85°C.

## Convert 470 K to Celsius Scale

To convert 470 K to Celsius Scale,

Let’s apply this formula to the given temperature

°C = K – 273.15

°C = 470 – 273.15

°C = 196.85

Therefore, 470 K is equal to 196.85°C.

Summary

## Convert the following temperatures to the Celsius scale. (a) 293 K (b) 470 K

After converting the following temperatures to the Celsius scale 293 K is equivalent to 19.85°C and 470 K is equivalent to 196.85°C. It is based on the properties of water, where 0 degrees Celsius (0°C) is defined as the freezing point of water, and 100 degrees Celsius (100°C) is defined as the boiling point of water at standard atmospheric pressure.
