Because the difference between the freezing point of water and the boiling point of water is 100° on both the Celsius and Kelvin scales, the size of a degree Celsius (°C) and a kelvin (K) are precisely the same. In contrast, both a degree Celsius and a kelvin are 9/5 the size of a degree Fahrenheit (°F).

The temperature at which the Fahrenheit scale and Kelvin scale gives the same reading is 301.43∘C in Celsius scale.

Celsius and Fahrenheit are degree scales. The degree symbol is not used to report temperature using the Kelvin scale, instead, they are noted as Kelvins. Water boils at 100 degrees Celsius or 212 degrees Fahrenheit, or 373.15 Kelvins. Water freezes at 0 degrees Celsius or 32 Degrees Fahrenheit, or 273.15 Kelvins.

The Four Types of Temperature Scales

• Fahrenheit Scale. ••• The Fahrenheit scale of temperature is the common form of temperature measurement used in the United States and some parts of the Caribbean.
• Celsius Scale. ••• Outside the United States, most of the world uses the Celsius scale to measure temperatures.
• Kelvin Scale. •••
• Rankine Scale. •••

There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin. Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts.

Temperature is not considered a dimension in the sense of space and time, because it doesn’t easily mix with space and time in an obvious way.

The three main temperature scales are Celsius, Fahrenheit, and Kelvin.

In thermodynamics: Temperature. … Fahrenheit scale is called the Rankine (°R) scale. These scales are related by the equations K = °C + 273.15, °R = °F + 459.67, and °R = 1.8 K. Zero in both the Kelvin and Rankine scales is at absolute zero.

The Kelvin (K) scale, an absolute temperature scale (obtained by shifting the Celsius scale by −273.15° so that absolute zero coincides with 0 K), is recognized as the international standard for scientific temperature measurement.

The unit difference between these two is the same but different starting point. Here, K = temperature on the Kelvin scale. D = temperature on the Celsius scale….Relation Between Celsius and Kelvin Scale.

The kelvin is now defined by fixing the numerical value of the Boltzmann constant k to 1.380 649×10−23 J⋅K−1. Hence, one kelvin is equal to a change in the thermodynamic temperature T that results in a change of thermal energy kT by 1.380 649×10−23 J.

The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy.

Historically, both scales center around defined points such as the melting point of ice, the temperature of the human body or the boiling point of water. The kelvin unit is not expressed in degrees like Celsius or Fahrenheit are. It is used by itself to describe temperature.

The major difference is that when water freezes, a Celsius thermometer will read 0°C, and a Kelvin thermometer will read 273.15 K. The scales differ by 273.15. Thus, to convert from °C to K simply add 273; if a thermometer reads 31°C then the temperature in Kelvin is 304K.

The correct one is just K, not degrees K. The confusion arises due to the other common temperatures scale, the Celsius scale (based on the old Centigrade scale). However, Kelvin, the SI unit of temperature, is based on the triple point of water (The temperature where water can exist in all 3 states).

On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values.

But what about absolute hot? It’s the highest possible temperature that matter can attain, according to conventional physics, and well, it’s been measured to be exactly 1,420,000,000,000,000,000,000,000,000,000,000 degrees Celsius (2,556,000,000,000,000,000,000,000,000,000,000 degrees Fahrenheit).

Negative absolute temperatures (or negative Kelvin temperatures) are hotter than all positive temperatures – even hotter than infinite temperature.

As such, absolute zero is, in essence, when all movement stops. The temperature is reached at -459.67 degrees Fahrenheit (-273.15 degrees Celsius). We’ve come pretty close to reaching this temperature. As such, it seems that the highest possible known temperature is 142 nonillion kelvins (1032 K.).

Facts about fahrenheit (f) In this scale, the freezing point of water is 32 degrees Fahrenheit (written “32 °F”), and the boiling point is 212 degrees, placing the boiling and freezing points of water exactly 180 degrees apart. Negative 40 degrees Fahrenheit (-40 °F) is equal to negative 40 degrees Celsius (-40 °C).
