Tips for accurate conversions
- The formula is °C = (°F − 32) × 5/9. Subtract 32 first, then multiply by 0.5556.
- Key reference points: 32°F = 0°C (freezing), 72°F ≈ 22°C (comfortable room), 98.6°F = 37°C (body temp), 212°F = 100°C (boiling).
- A quick mental shortcut: subtract 30 from °F and halve it for a rough Celsius estimate.
