Fahrenheit to Celsius — Common Temperatures
Quick formula: °C = (°F − 32) × 5/9. Fast estimate: subtract 30, divide by 2 (e.g., 70°F → (70-30)/2 = 20°C approx).

Frequently Asked Questions
How do you convert Fahrenheit to Celsius?
Subtract 32, then multiply by 5/9. Formula: °C = (°F - 32) × 5/9. Example: 98.6°F = (98.6 - 32) × 5/9 = 37°C.
What is 100°F in Celsius?
100°F = 37.78°C. Calculated as (100 - 32) × 5/9 = 37.78°C. Normal body temperature is 98.6°F = 37°C.
What is 72°F in Celsius?
72°F = 22.22°C. Comfortable room temperature range is 68–77°F (20–25°C).
What is 32°F in Celsius?
32°F = 0°C. This is the freezing point of water. Water freezes at 0°C / 32°F and boils at 100°C / 212°F.
At what temperature are Fahrenheit and Celsius the same?
Both scales are equal at -40°. That is, -40°F = -40°C exactly.
What is the formula to convert Celsius to Fahrenheit?
°F = (°C × 9/5) + 32. Example: 100°C = (100 × 9/5) + 32 = 212°F. Quick estimate: double the Celsius, add 30 (e.g., 20°C → 40 + 30 = 70°F approx).
