**The Kelvin Scale**

The Kelvin scale is a temperature scale that is often used in scientific and engineering applications. It is based on the absolute zero point, which is defined as the temperature at which all molecular motion ceases. On the Kelvin scale, the temperature is measured in kelvin (K) units.

**The Celsius Scale**

The Celsius scale is a commonly used temperature scale that is based on the freezing and boiling points of water. On the Celsius scale, the temperature is measured in degrees Celsius (°C) units.

**Converting Kelvin to Celsius**

To convert a temperature from Kelvin to Celsius, you can use the following formula:

°C = K - 273.15

where °C represents the temperature in degrees Celsius and K represents the temperature in Kelvin.

**Applying the Formula**

Now, let's apply the formula to convert a given temperature of 270 K to degrees Celsius.

°C = 270 - 273.15

To simplify the calculation, we first subtract the decimal part:

0.15 - 0.15 = 0

Next, we subtract the whole number parts:

270 - 273 = -3

Therefore, the Celsius temperature equivalent to 270 K is -3°C.

**Explanation**

The Kelvin scale starts from absolute zero, where there is no molecular motion. As the temperature increases, molecular motion also increases. The Celsius scale, on the other hand, is based on the freezing and boiling points of water. 0°C represents the freezing point of water, and 100°C represents the boiling point of water at sea level.

To convert a temperature from Kelvin to Celsius, we subtract 273.15 from the Kelvin temperature. This is because 0°C on the Celsius scale is equivalent to 273.15 K on the Kelvin scale. By subtracting this value, we can find the corresponding temperature in degrees Celsius.

In this case, the given temperature is 270 K. By subtracting 273.15 from 270, we find that the corresponding Celsius temperature is -3°C. The negative sign indicates that the temperature is below freezing point.

In summary, the corresponding Celsius temperature for 270 K is -3°C.
