Fahrenheit to Celsius Converter °F → °C
1 °F equals -17.22222222 °C — note this scale uses an offset formula, not simple multiplication. Type a value below — the conversion happens instantly, entirely on your device.
98.6 °F = 37 °C
98.6 degrees Fahrenheit = 37 degrees Celsius
98.6 × 0.555556 − 17.7778 = 37
These scales have different zero points, so the conversion multiplies by 0.555556 and then shifts by −17.7778.
How to convert degrees Fahrenheit to degrees Celsius
°C = (°F − 32) × 5/9 — subtract 32 from the Fahrenheit temperature, then multiply by 5/9.
Example: 98.6 °F = 37 °C.
To convert the other way: °F = (°C × 9/5) + 32 — or use the dedicated °C to °F converter .
Fahrenheit-to-Celsius converts US weather, oven and body temperatures for the rest of the world. Key anchors: 32 °F = 0 °C, 68 °F = 20 °C, 98.6 °F = 37 °C, 212 °F = 100 °C. Mental shortcut: subtract 30 and halve (86 °F → 28 ≈ 30 °C exact).

About the units
What is the Fahrenheit scale?
Degrees Fahrenheit (°F) place water’s freezing point at 32° and boiling point at 212°. It is the everyday temperature scale in the United States.
What is the Celsius scale?
Degrees Celsius (°C) set 0° at the freezing point of water and 100° at its boiling point (at standard pressure). It is the everyday temperature scale in almost every country.
