Unit of Temperature

Unit of Temperature

In this article, we introduce the Unit of Temperature and the method of converting each of these units to each other.

Many devices have been invented to accurately measure temperature. It all started with the establishment of a temperature scale. This scale transformed the measurement of temperature into meaningful numbers.

What is the temperature?

Temperature is a measure of the internal thermal energy state of a substance. It represents how much vibrational energy exists in the molecules of a liquid or solid, or the translational energy (speed of movement) of molecules in a gas.

Fahrenheit

The degree Fahrenheit ( ^o F) is the unit of temperature used by most people in the United States in describing weather.

The scale derives its name from a German-born physicist, Daniel Gabriel Fahrenheit, who is recognized as having invented it. At standard Earth-atmospheric sea-level pressure, pure water freezes at 32 ^o F and boils at +212 ^o F.

Celsius scale

The Celsius scale, previously known as the centigrade scale, is a temperature scale used by the International System of Units (SI).

As an SI derived unit, it is used by all countries except the United States, the Bahamas, Belize, the Cayman Islands, and Liberia.

It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale.

The degree Celsius (°C) can refer to a specific temperature on the Celsius scale or a unit to indicate a difference between two temperatures or uncertainty.

Before being renamed to honor Anders Celsius in 1948, the unit was called centigrade, from the Latin centum, which means 100, and grades, which means steps.

Kelvin Scale

The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area.

While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement.

As a result, the Kelvin Scale does not use degrees, but simply a number followed by “K” for Kelvin.

The Kelvin Scale begins at absolute zero (equivalent to -273.15° C), which is the temperature at which all objects stop moving, and ends at the triple point of water (equivalent to 0.01°C), which is the temperature at which water exists in all three states of matter simultaneously.

temperature unit conversion

 From Celsius to Fahrenheit

• [°F] = [°C] ×9/5   + 32

From Fahrenheit to Celsius

• [°C] = ([°F] − 32) ×5/9

From Celsius to Kelvin

• [K] = [°C] + 273.15

From Kelvin to Celsius

• [°C] = [K] − 273.15

From Kelvin to Fahrenheit

• [°F] = [K] × 9/5   − 459.67

From Fahrenheit to Kelvin

• [K] = ([°F] + 459.67) *5/9
