What is 21 Degrees Celsius in Fahrenheit?

Answer: 1 degrees Celsius is equal to 69.8 degrees Fahrenheit.

To convert from Celsius to Fahrenheit, you can use the formula:

°F = (°C × 9/5) + 32

Now, you want to convert 21 degrees Celsius to Fahrenheit:

°F = (21 × 9/5) + 32

Perform the calculations:

°F = (189/5) + 32

To add these fractions, you’ll need a common denominator:

°F = (189/5) + (32 × 5/5)

°F = (189 + 160)/5

°F = 349/5

Now, divide to get the decimal value:

°F = 69.8

So, 21 degrees Celsius is equivalent to 69.8 degrees Fahrenheit. This conversion is useful when you need to understand temperatures in different parts of the world, especially as Celsius is used in most countries while Fahrenheit is commonly used in the United States.
