How to Convert Fahrenheit to Celsius
Converting Fahrenheit to Celsius is essential when traveling to countries using metric temperatures. This is commonly needed for weather forecasts, oven temperatures, and scientific calculations.
32.0 °F = 0.00 °C
To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9 (or 0.5556).
Step-by-Step
- Start with your value: 32.0 °F
- Subtract 32
- Multiply by 5/9 (or 0.5556)
- Result: 0.00 °C
Formula: °C = (°F - 32) × 5/9
💡 Memory Tip: 32°F = 0°C (freezing). 68°F = 20°C (room temp). 212°F = 100°C (boiling). Quick estimate: subtract 32, then halve (for close approximation).

Understanding Fahrenheit and Celsius
What is Fahrenheit?
Fahrenheit (°F) is a temperature scale primarily used in the United States. Water freezes at 32°F and boils at 212°F. The scale was created by Daniel Gabriel Fahrenheit in 1724.
What is Celsius?
Celsius (°C) is a temperature scale used by most countries worldwide. Water freezes at 0°C and boils at 100°C at sea level. The scale was originally called centigrade and is part of the metric system.
