How to Convert Celsius (°C) to Fahrenheit (°F)
To convert any temperature from Celsius (°C) to Fahrenheit (°F), multiply the Celsius temperature by 1.8 (or 9/5) and then add 32.
Exact Mathematical Formula
°F = (°C × 1.8) + 32
Or fraction equivalent: °F = (°C × 9/5) + 32
Quick Mental Math Approximation
°F ≈ (°C × 2) + 30
Example: 20°C × 2 = 40 + 30 = ~70°F (actual 68°F)
Step-by-Step Celsius to Fahrenheit Examples
Example 1: Room Temperature (20°C)
- Step 1: Multiply by 1.8 →
20 × 1.8 = 36 - Step 2: Add 32 →
36 + 32 = 68°F - Result: 20°C = exactly 68°F
Example 2: Body Temperature (37°C)
- Step 1: Multiply by 1.8 →
37 × 1.8 = 66.6 - Step 2: Add 32 →
66.6 + 32 = 98.6°F - Result: 37°C = exactly 98.6°F
Example 3: Oven Baking (180°C)
- Step 1: Multiply by 1.8 →
180 × 1.8 = 324 - Step 2: Add 32 →
324 + 32 = 356°F - Result: 180°C = 356°F (~350°F standard baking)

Frequently Asked Questions (FAQ)
How do you convert Celsius to Fahrenheit easily?
Multiply the Celsius temperature by 1.8 and add 32. For instant mental estimates, double the number and add 30 (e.g., 15°C × 2 = 30 + 30 = ~60°F, actual 59°F).
What is 20°C in Fahrenheit?
20°C equals exactly 68°F, representing comfortable indoor room temperature.
What is 100°C in Fahrenheit?
100°C equals exactly 212°F, which is the boiling point of pure water at sea level atmospheric pressure.
How does fan-forced (convection) oven temperature compare?
Fan-assisted convection ovens circulate air more efficiently, so you should reduce conventional oven temperatures by 20°C (approx. 25°F to 35°F). For example, 180°C conventional = 160°C fan-forced.
