When it comes to temperature measurement, there are two commonly used scales: Fahrenheit and Celsius. While both are used to measure the same physical quantity, temperature, they differ in the way they are defined and their numerical values.
In this article, we will discuss the science behind temperature conversion and provide a step-by-step guide on how to convert temperatures from Fahrenheit to Celsius and vice versa. Whether you are a student, a scientist, or a professional in the field of thermodynamics, this article will provide you with a comprehensive understanding of temperature conversion.
Fahrenheit to Celsius Formula Scale
The Fahrenheit scale, developed by physicist Daniel Gabriel Fahrenheit in 1724, is a temperature scale that defines the freezing point of water as 32°F and the boiling point of water as 212°F at standard atmospheric pressure.
One of the main advantages of the Fahrenheit scale is that it is more intuitive than the Celsius scale. For example, room temperature is typically around 68°F to 72°F, which is a range that is easily recognizable to most people.
Celsius to Fahrenheit Scale
The Celsius scale, also known as the centigrade scale, was developed by Swedish astronomer Anders Celsius in 1742. Unlike the Fahrenheit scale, the Celsius scale defines the freezing point of water as 0°C and the boiling point of water as 100°C at standard atmospheric pressure.
The Celsius scale is widely used in scientific and engineering applications, particularly in the field of thermodynamics. This is because the Celsius scale provides a more convenient and consistent measurement of temperature compared to the Fahrenheit scale.
Converting Fahrenheit to Celsius
The conversion formula for converting temperatures from Fahrenheit to Celsius is simple and straightforward. The formula is as follows:
°C = (°F - 32) × 5/9
To use this formula, simply subtract 32 from the temperature in Fahrenheit and then multiply the result by 5/9. The resulting value will be the temperature in Celsius.
Here’s an example:
Let's say you want to convert 68°F to Celsius. °C = (68°F - 32) × 5/9 °C = (36) × 5/9 °C = 20°C
As you can see, 68°F is equivalent to 20°C on the Celsius scale.
Converting Celsius to Fahrenheit
To convert temperatures from Celsius to Fahrenheit, you can use the following formula:
°F = (°C × 9/5) + 32
To use this formula, simply multiply the temperature in Celsius by 9/5 and then add 32. The resulting value will be the temperature in Fahrenheit.
Here’s an example:
Let's say you want to convert 20°C to Fahrenheit. °F = (20°C × 9/5) + 32 °F = (36) + 32 °F = 68°F
As you can see, 20°C is equivalent to 68°F on the Fahrenheit scale.
Convert Celsius to Kelvin
Celsius (°C) and Kelvin (K) are two of the most commonly used units of measurement for temperature. While Celsius is widely used in everyday life, Kelvin is more commonly used in scientific and industrial settings. Understanding the conversion between these two units can be useful for many practical applications, including weather forecasting, cooking, and heating and cooling systems. In this article, we’ll explore the basics of Celsius and Kelvin, the conversion formula between the two, and provide some useful tips and tricks to help you convert temperatures accurately and easily.
How to Convert Fahrenheit to Kelvin
The formula to convert Fahrenheit to Kelvin is relatively simple. The conversion formula is as follows:
K = (°F + 459.67) ÷ 1.8
To convert a temperature from Fahrenheit to Kelvin, simply add 459.67 to the temperature in Fahrenheit and then divide the result by 1.8. The resulting number will be the temperature in Kelvin.
Example of Fahrenheit to Kelvin Conversion
Let’s say you want to convert 68°F to Kelvin. Using the formula above, you would perform the following calculation:
K = (68 + 459.67) ÷ 1.8 K = 527.67 ÷ 1.8 K = 293.15 K
So, 68°F is equivalent to 293.15 K.
How to Convert Kelvin to Celsius
The formula to convert Kelvin to Celsius is relatively simple. The conversion formula is as follows:
°C = K – 273.15
To convert a temperature from Kelvin to Celsius, simply subtract 273.15 from the temperature in Kelvin. The resulting number will be the temperature in Celsius.
Example of Kelvin to Celsius Conversion
Let’s say you want to convert 293.15 K to Celsius. Using the formula above, you would perform the following calculation:
°C = 293.15 – 273.15 °C = 20°C
So, 293.15 K is equivalent to 20°C.
Temperature conversion is a fundamental concept in the field of thermodynamics and is used in a variety of applications. Whether you are a student, a scientist, or a professional in the field of thermodynamics, it is important to understand how to convert temperatures from one scale to another.
