Conversion Examples
Step-by-Step Example:
Convert 77°F to Celsius:
1. Subtract 32: 77 - 32 = 45
2. Multiply by 5/9: 45 × 5/9 = 25°C
Result: 77°F = 25°C
Usage Tips
- •Remember: 32°F = 0°C (water freezing point)
- •Quick estimate: Subtract 30, then halve
- •Body temperature: 98.6°F = 37°C
- •Room temperature: 68-72°F = 20-22°C
- •Cooking: 350°F = 177°C (moderate oven)
