A convection oven is set lower than a conventional oven for the same recipe. 20 °C is the usual figure (Which?) and 25 °F the usual US rule of thumb. Both are editorial rules of thumb, and 20 °C is 36 °F, so they are not the same size. Many ovens adjust automatically. Check your manual.

200 °C × 9 ÷ 5 + 32 = 392 °F. The dial value is rounded to the nearest 10 °C or 25 °F.

Ovens vary, so use an oven thermometer to check.
