375°F to Celsius — all four oven scales
The exact conversion is (°F − 32) × 5/9, so 375°F works out to 190.6°C. Recipe writers round this to 190°C — the long-standing pairing that also maps to gas mark 5 — because no home oven holds a fraction of a degree and no dial displays one. The 0.6°C of rounding is far smaller than a typical oven's swing around its set point.
In a fan (convection) oven, use 170°C — the standard adjustment is conventional minus 20°C, because moving air transfers heat faster than still air. Make the temperature adjustment or shorten the bake time by about a quarter, never both. Bake times are otherwise unaffected by converting between scales: 190°C and 375°F are the same heat wearing different units.
Where 375°F sits on the chart
| °F | °C | Fan °C | Gas mark | Descriptor |
|---|---|---|---|---|
| 325°F | 160°C | 140°C | 3 | Moderately slow |
| 350°F | 180°C | 160°C | 4 | Moderate |
| 375°F | 190°C | 170°C | 5 | Moderately hot |
| 400°F | 200°C | 180°C | 6 | Moderately hot |
| 425°F | 220°C | 200°C | 7 | Hot |

What bakes at this temperature
375°F / 190°C is the territory of cookies, muffins and enriched breads. Remember that most home ovens swing ±25°F around their set point and many run permanently hot or cold — a standalone oven thermometer on the middle rack tells you more than any conversion chart can.
