Frequently Asked Questions

What is the formula?

The formula is °C = (°F − 32) × 5/9. Subtract 32 from Fahrenheit, then multiply by 5/9 (divide by 1.8).

Is there a quick mental estimate?

Subtract 30, then halve it. For 100°F: (100−30)÷2 = 35°C (actual: 37.8°C).

What temperature is the same in both scales?

The scales meet at -40°: -40°F equals -40°C exactly.

What is normal body temperature in Celsius?

Normal body temperature of 98.6°F equals 37°C. A fever generally starts around 100.4°F (38°C).
