273.15 Kelvin (K)

0 Celsius (°C)

Kelvin : The Kelvin (symbol: K) is a unit of measurement for temperature, which also is one of the seven base units in the International System of Units (SI). The Kelvin is the major unit of measurement in the physical sciences, but is often used in conjunction with the degree Celsius.

Celsius : Celsius, also known as centigrade, is a unit of measurement for temperature. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval, a difference between two temperatures or an uncertainty. In 1948, the 9th CGPM and the CIPM formally adopted "degree Celsius".

FAQ about Kelvin to Celsius Conversion

0 degrees Kelvin is equal to -273.15 degrees Celsius:

0 K = -273.15 °C

The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:

T(°C) = T(K) - 273.15

373.15 Kelvin is equal to 100 Celsius:

373.15K = 373.15K - 273.15 = 100°C

0 Celsius is equal to 273.15 Kelvin:

0°C = 0°C + 273.15 = 273.15K

T(°C) = 303.15(K) - 273.15 = 30°C

What is the boiling point of water in Celsius and Kelvin?
Gulshan Oct 11, 2016 at 20:45 pm
Hi Wilber,
The freezing point of water is the temperature at which water changes its state from liquid to solid. The freezing point of water is different in Celsius and Kelvin scales.

In Celsius, the freezing point of water is 0°C. This means that at this temperature, water will freeze and turn into ice if it is cooled below 0°C.

In Kelvin, the freezing point of water is 273.15 K. The Kelvin scale is an absolute temperature scale that starts at absolute zero. On this scale, the size of one degree is the same as one Celsius degree, but the zero point is shifted. The Kelvin scale starts at zero (0 K), equivalent to -273.15°C. So, the freezing point of water in Kelvin is 273.15 K.

So, to summarize:
The freezing point of water in Celsius = 0°C
The freezing point of water in Kelvin = 273.15 K

What is the boiling point of water in Celsius and Fahrenheit?
Gulshan Nov 13, 2015 at 11:24 am
Hi Iyaad, The boiling point of water is the temperature at which water changes its state from liquid to gas. The boiling point of water is different in Celsius and Fahrenheit scales. In Celsius, the boiling point of water is 100°C, which means that water will boil and turn into steam at this temperature when heated at standard atmospheric pressure (sea level). In Fahrenheit, the boiling point of water is 212°F, which means that water will boil and turn into steam at this temperature when heated at standard atmospheric pressure (sea level).
So, to summarize:

The boiling point of water in Celsius = 100°C

The boiling point of water in Fahrenheit = 212°F

Does any country use the Kelvin temperature scale?
Gulshan Feb 19, 2014 at 21:23 pm
Hi Jeff, Kelvin is only used for scientific computing. It is more convenient to use Celsius. Most countries use Celsius while the US uses Fahrenheit. So Celsius to Fahrenheit is a commonly used converter.
