# What Is 21 Degrees Celsius In Fahrenheit?

If you need to convert temperatures between Celsius and Fahrenheit, you may be wondering what 21 degrees Celsius is in Fahrenheit. The answer is 69.8 degrees Fahrenheit.

## Celsius and Fahrenheit Explained

Celsius and Fahrenheit are two different temperature scales used to measure temperature. Celsius is the standard used by most countries in the world, including the European Union and the United States of America. The Celsius scale is the most commonly used temperature scale around the globe. In the Celsius scale, 0 degrees is the freezing point of water and 100 degrees is the boiling point of water.

Fahrenheit is an alternative temperature scale that is used mainly in the United States, as well as some Caribbean countries and the Bahamas. The freezing point of water in the Fahrenheit scale is 32 degrees, and the boiling point of water is 212 degrees.

## How to Convert Between Celsius and Fahrenheit

To convert between Celsius and Fahrenheit, you can use a simple formula. To convert Celsius to Fahrenheit, you need to multiply the temperature in Celsius by 1.8 and then add 32. To convert Fahrenheit to Celsius, you need to subtract 32 from the temperature in Fahrenheit and then divide by 1.8.

For example, if you have a temperature of 21 degrees Celsius, you can convert it to Fahrenheit by multiplying 21 by 1.8 and then adding 32. This will give you a temperature of 69.8 degrees Fahrenheit.

## Understanding the Differences in Temperature Scales

It is important to understand the differences between the two temperature scales. In the Celsius scale, the freezing point of water is 0 degrees, while in the Fahrenheit scale, the freezing point of water is 32 degrees. This means that a temperature of 0 degrees Celsius is 32 degrees Fahrenheit. Similarly, a temperature of 100 degrees Celsius is 212 degrees Fahrenheit.

It is also important to note that the two temperature scales use different increments. In the Celsius scale, the increments between temperatures are 1 degree, whereas in the Fahrenheit scale, the increments between temperatures are 1.8 degrees.

## Why is Knowing the Difference Between Celsius and Fahrenheit Important?

Knowing the difference between Celsius and Fahrenheit is important when it comes to measuring and understanding temperature. Many countries use the Celsius scale as their official temperature scale, so it is important to understand how to convert between the two scales.

In addition, understanding the difference between Celsius and Fahrenheit is important when it comes to reading temperature charts, such as weather forecasts. Many weather forecasts use the Celsius scale, so it is important to be able to convert between the two scales in order to accurately interpret the forecast.

## Conclusion

21 degrees Celsius is equal to 69.8 degrees Fahrenheit. It is important to understand the difference between Celsius and Fahrenheit, as well as how to convert temperatures between the two scales. Knowing the difference and how to convert between the two scales is essential for accurately reading temperature charts and forecasts.
