150°C to Fahrenheit — all four oven scales
The exact conversion is °C × 9/5 + 32, so 150°C works out to 302°F. Recipe writers don't use the exact figure: the long-standing pairing puts 150°C alongside 300°F and gas mark 2, and since a home oven swings around its set point by more than the rounding difference, the paired values are interchangeable in practice. Follow whichever scale your dial shows.
In a fan (convection) oven, use 130°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: 150°C and 300°F are the same heat wearing different units.
Where 150°C sits on the chart
| °F | °C | Fan °C | Gas mark | Descriptor |
|---|---|---|---|---|
| 250°F | 120°C | 100°C | ½ | Very slow |
| 275°F | 140°C | 120°C | 1 | Slow |
| 300°F | 150°C | 130°C | 2 | Slow |
| 325°F | 160°C | 140°C | 3 | Moderately slow |
| 350°F | 180°C | 160°C | 4 | Moderate |

What bakes at this temperature
300°F / 150°C is the territory of rich fruit cakes and other long, slow bakes. 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.
