Celsius to Fahrenheit temperature conversion online formula

°F = (°C × 9/5) + 32

°C = (°F − 32) × 5/9

Celsius (°C)

Celsius is a temperature scale used worldwide, based on the metric system. It sets:

• 0°C as the freezing point of water

• 100°C as the boiling point of water (at 1 atm pressure)

It is widely used in science, daily life, and weather reports across most countries.

Fahrenheit (°F)

Fahrenheit is a temperature scale mainly used in the United States and some Caribbean nations. On this scale:

• Water freezes at 32°F

• Water boils at 212°F

It is still commonly seen in cooking, thermostats, and weather updates in the U.S.

Formula

• °F = (°C × 9/5) + 32

• °C = (°F − 32) × 5/9

Example: Convert 15°C to Fahrenheit: 15 × 9/5 + 32 = 59°F
