Before we show the Celsius to Fahrenheit conversion, let's share some interesting facts about Celsius:

• Anders Celsius is the name of the Swedish astronomer and mathematician who invented the temperature scale in 1742.

• Originally, the boiling point of water was set at 0°C, and its melting point at 100°C. Later, it was reversed.

• We also call this scale the centigrade scale because it has 100-degree intervals between the freezing and boiling points of water.

To use the Celsius to Fahrenheit converter:

1. Enter the temperature in Celsius in the first field, for example, 20°C.

2. The calculator will convert it to Fahrenheit and display it in the second field, for example, 68°F.

3. You can also use it in reverse by entering a temperature in Fahrenheit to get the temperature in Celsius.

4. Additionally, you can switch any of the temperature units to convert them to Kelvin.

Here is the formula for converting Celsius to Fahrenheit:

• $°F=(°C\times 9/5)+32$

And here is the formula for converting Fahrenheit to Celsius:

• $°C=(°F-32)\times 5/9$

Where:

• $°F$ - temperature unit in Fahrenheit; and also
• $°C$ - temperature unit in Celsius.

Example:

1. Let's use the formula to convert the boiling point of water, i.e., 100°C, to Fahrenheit.

   Substituting values into the first formula, we get:

   $°F=(100\times 9/5)+32=212$

   So, if we convert 100°C to Fahrenheit, we get 212°F.

2. Now let's convert 212°F back to Celsius.

   Substituting values into the second formula, we get:

   $°C=(212-32)\times 5/9=100$

   So, if we convert 212°F back to Celsius, we still get 100°C.
