Temperature

What is Temperature?

Temperature is a measure of how hot or cold something is. It is a fundamental concept in science and is used in various fields such as physics, chemistry, and meteorology.

Units of Temperature

There are different units of temperature measurement, but the most commonly used ones are Celsius (°C), Fahrenheit (°F), and Kelvin (K).

Celsius (°C)

The Celsius scale is based on the freezing and boiling points of water, where 0°C is the freezing point and 100°C is the boiling point at standard atmospheric pressure.

Fahrenheit (°F)

The Fahrenheit scale is also based on the freezing and boiling points of water, but uses different reference points. 32°F is the freezing point and 212°F is the boiling point at standard atmospheric pressure.

Kelvin (K)

The Kelvin scale is based on absolute zero, the lowest possible temperature. Absolute zero is 0 Kelvin, which is equivalent to -273.15°C. The Kelvin scale is commonly used in scientific research and calculations.

Converting Between Temperature Scales

To convert between Celsius and Fahrenheit, you can use the following formulas:

Fahrenheit to Celsius: C = (F - 32) * 5/9

Celsius to Fahrenheit: F = (C * 9/5) + 32

To convert between Celsius and Kelvin, you can use the following formula:

Kelvin = Celsius + 273.15

Temperature Measurement Devices

There are various devices used to measure temperature, such as thermometers, infrared thermometers, and thermocouples. These devices provide accurate readings of temperature in different environments and for various applications.
