What is the formula for Fahrenheit to Celsius?

Subtract 32 from the Fahrenheit value, then multiply by 5/9. Example: (72°F - 32) = 40, then 40 × 5/9 ≈ 22.2°C.

What is 37°C in Fahrenheit (body temperature)?

37°C × 1.8 + 32 = 98.6°F. Normal human body temperature is 37°C or 98.6°F.

Can I convert negative Fahrenheit temperatures?

Yes. The formula works for any temperature including negative values. -40°F = -40°C (the only point where both scales are equal).
