What is Celsius?
Celsius, also known as centigrade, is a temperature scale used to measure temperature. It is based on the freezing point of water at 0°C and the boiling point at 100°C under standard atmospheric pressure. The Celsius scale is widely used in most countries around the world for everyday temperature measurements, such as weather forecasts and cooking.
What is Fahrenheit?
Fahrenheit is another temperature scale commonly used in the United States and a few other countries. On this scale, water freezes at 32°F and boils at 212°F under standard atmospheric pressure. The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in the early 18th century.

Converting Celsius to Fahrenheit involves a simple mathematical formula:
°F = (°C × 9/5) + 32
To convert a temperature from Celsius to Fahrenheit, follow these steps:
- Multiply the Celsius temperature by 9.
- Divide the result by 5.
- Add 32 to the value obtained.
This formula allows you to accurately convert any temperature from Celsius to Fahrenheit.
Example 1: Converting 15°C to Fahrenheit
- °F = (15 × 9/5) + 32
- First, multiply 15 by 9 to get 135.
- Then divide 135 by 5, which equals 27.
- Finally, add 32 to 27. The result is 59°F.
So, 15°C is equal to 59°F.
Example 2: Converting 37°C to Fahrenheit
- °F = (37 × 9/5) + 32 Multiply 37 by 9 to get 333.
- Divide 333 by 5 to get 66.6.
- Add 32 to 66.6, resulting in 98.6°F.
Therefore, 37°C is equivalent to 98.6°F.
