To convert Fahrenheit to Celsius: subtract 32, then multiply by 5/9. For 98.6°F body temperature: (98.6 - 32) x 5/9 = 37°C. For 350°F oven: (350 - 32) x 5/9 = 176.7°C.
The converter above handles this automatically — enter any Fahrenheit value and the Celsius result appears instantly. The temperature tab supports Celsius, Fahrenheit, and Kelvin.
The Fahrenheit to Celsius Formula
The exact formula is: °C = (°F - 32) × 5/9
Step by step: (1) take your Fahrenheit temperature, (2) subtract 32, (3) multiply by 5 and divide by 9. You can also write the multiplier as 0.5556 instead of 5/9 — same result.
To go the other direction (Celsius to Fahrenheit): multiply by 9/5, then add 32. The converter does both directions automatically.

| 104°F | 40°C | high fever |
| 212°F | 100°C | water boils |
Fahrenheit to Celsius for Oven Temperatures
| Fahrenheit | Celsius | Oven Level |
|---|---|---|
| 250°F | 120°C | very low (drying, dehydrating) |
| 300°F | 149°C | low (slow baking) |
| 325°F | 163°C | low-moderate (delicate pastries) |
| 350°F | 177°C | moderate (standard baking) |
| 375°F | 190°C | moderate-hot |
| 400°F | 204°C | hot (roasting, bread) |
| 425°F | 218°C | very hot |
| 450°F | 232°C | high (pizza, searing) |
Quick Mental Estimation
A rough shortcut: subtract 30 from Fahrenheit, then divide by 2. This is slightly off but fast — 70°F becomes (70-30)/2 = 20°C (exact answer is 21.1°C). Good enough for weather, not precise enough for cooking.
For body temperature specifically: 98.6°F = 37°C is worth memorizing. A fever in Celsius starts at 38°C (100.4°F).
