How to Convert Celsius to Fahrenheit
Multiply the Celsius temperature by 9/5 (or 1.8), then add 32:
Example: 22°C (room temperature)
= (22 × 1.8) + 32 = 39.6 + 32 = 71.6°F
Example: 37°C (body temperature)
= (37 × 1.8) + 32 = 66.6 + 32 = 98.6°F
Example: 180°C (oven for baking)
= (180 × 1.8) + 32 = 324 + 32 = 356°F
Mental math shortcut: Double it and add 30. Example: 22°C → (22 × 2) + 30 = 74°F (actual: 71.6°F). Good enough for a quick estimate!

What Is Celsius?
Celsius (°C), formerly called centigrade, is the world's most widely used temperature scale. It was designed by Anders Celsius in 1742 with 0°C as the freezing point and 100°C as the boiling point of water — a clean, logical 100-degree range. Every country except the US and a few territories uses Celsius for weather, cooking, and everyday temperature.
What Is Fahrenheit?
Fahrenheit (°F) was developed by Daniel Gabriel Fahrenheit in 1724. Water freezes at 32°F and boils at 212°F. While less intuitive than Celsius, Fahrenheit provides finer granularity per degree — the 180-degree range (32–212) vs. 100-degree range (0–100) means each °F is a smaller change than each °C, which some argue makes it better for describing weather.
