21 Degrees Celsius (C) Equals 69.8 Degrees Fahrenheit (F)

or 21 C = 69.8 F

## How to Convert 21 C to F (Celsius to Fahrenheit)

Learn how to convert Celsius to Fahrenheit quickly below. To convert C to F in general, multiply C by 1.8 (or 9/5) and then add 32.

A factor of conversion:

1 C = (1 C * 1.8) + 32 = 33.8 F

21 C through F Equation of Conversion

21 C = (21 C * 1.8) +32 = 69.8 F

## What is Celsius (C)?

Celsius (C), often known as centigrade, is the temperature unit in the Metric System of Measurement. This temperature scale is based on the freezing point of water at 0 degrees Celsius and the boiling point of water at 100 degrees Celsius.

“C” is the abbreviation for Celsius. 21 degrees Celsius, for example, can be written as 21 C.

## What is Fahrenheit (F)?

Fahrenheit (F) is the Imperial System of Measurement’s temperature unit. This system remains based on scientist Daniel Gabriel Fahrenheit’s temperature scale. Water has a freezing point of 32 degrees Fahrenheit and a boiling temperature of 212 degrees Fahrenheit in the Fahrenheit system.

Fahrenheit remains represented by the abbreviation “F”. 21 degrees Fahrenheit, for example, can be written as 21 F.

## Conclusion

A long day in the sun might be exhausting, so 21 with a little cloud can be a terrific beach day. We’d go early and leave by 10, or wait until after 6! I wouldn’t swim in the sea if the water temperature were below 18 degrees Celsius. 21 for us!
