### Key Takeaways:

• The Celsius and Fahrenheit scales are the two most commonly used temperature scales.
• Understanding the formulas for converting between Celsius and Fahrenheit is crucial.
• To convert 100 degrees Fahrenheit to Celsius, use the formula °C = (°F – 32) / 1.8.
• Double-checking your calculations and using online conversion tools can ensure accuracy.
• Remember to consider the limitations and differences between the Celsius and Fahrenheit scales when converting temperatures.

## Understanding the Celsius and Fahrenheit Scales

When it comes to measuring temperature, two scales dominate: Celsius (°C) and Fahrenheit (°F). While Celsius is used extensively worldwide, Fahrenheit is primarily utilized in the United States. Understanding these temperature scales is essential for accurate temperature conversion.

The Celsius temperature scale, also known as the centigrade scale, was developed by Swedish astronomer Anders Celsius. It is based on the freezing and boiling points of water, with 0°C representing the freezing point and 100°C signifying the boiling point at sea level.

On the other hand, the Fahrenheit temperature scale was devised by Daniel Gabriel Fahrenheit, a Polish-German physicist. In this scale, the freezing point of water is marked as 32°F, while the boiling point is set at 212°F at sea level.

While both scales measure temperature, they have different interval sizes between degrees. One degree Celsius is equivalent to 1.8 degrees Fahrenheit, making Fahrenheit intervals larger than Celsius intervals. This means that a change of 1 degree Fahrenheit corresponds to a smaller change in Celsius.

It’s worth noting that 0°C and 32°F indicate the same temperature; however, the numerical values differ due to the variation in scale intervals.

Converting temperatures between Celsius and Fahrenheit requires a conversion formula, which will be discussed in later sections. Being familiar with these scales and their differences will enable you to accurately convert temperatures and interpret them in various contexts.

Now, let’s take a closer look at the conversion formulas, starting with converting Celsius to Fahrenheit.

Now that we have a better understanding of the Celsius and Fahrenheit scales, let’s move on to exploring the formula for converting Celsius to Fahrenheit in the next section.

## Celsius to Fahrenheit Formula

Converting temperatures from Celsius to Fahrenheit is a straightforward process that uses a simple formula. By understanding and applying the Celsius to Fahrenheit formula, you can accurately convert Celsius temperatures into their Fahrenheit equivalents.

To convert Celsius to Fahrenheit, use the following formula:

°F = (°C * 1.8) + 32

This formula involves two simple steps:

1. Multiply the Celsius temperature by 1.8.
2. Add 32 to the result.

By following these steps, you can quickly and precisely convert Celsius temperatures to Fahrenheit.

### Example:

Let’s use the Celsius to Fahrenheit formula to convert 20 degrees Celsius to Fahrenheit:

°F = (20 * 1.8) + 32

°F = 36 + 32

°F = 68

Therefore, 20 degrees Celsius is equal to 68 degrees Fahrenheit.

With this formula, you can easily convert any Celsius temperature to Fahrenheit. Whether you need to convert temperatures for cooking, scientific calculations, or everyday use, this formula provides a reliable method for accurate conversions.

## Fahrenheit to Celsius Formula

Converting temperatures from Fahrenheit to Celsius is a straightforward process that relies on a specific formula. By using this formula, you can accurately convert Fahrenheit temperatures to Celsius in no time.

Formula: °C = (°F – 32) / 1.8

The formula indicates that to convert a Fahrenheit temperature to Celsius, you subtract 32 from the Fahrenheit temperature and then divide the result by 1.8. This calculation will give you the equivalent Celsius temperature.

Let’s take an example to illustrate the formula:

1. Starting with a Fahrenheit temperature of 100°F, we can apply the formula as follows:
• First, subtract 32 from 100°F: 100 – 32 = 68
• Next, divide the result by 1.8: 68 / 1.8 ≈ 37.8
2. Therefore, 100 degrees Fahrenheit is approximately equal to 37.8 degrees Celsius.

Using this formula, you can convert any Fahrenheit temperature to Celsius with precision. As a handy temperature conversion tool, make sure to keep this formula in mind when you need to switch between the Fahrenheit and Celsius scales.

Now that you know the formula, let’s explore practical examples of converting different Fahrenheit temperatures to Celsius in the next section.
