325°F = 165°C Oven (145°C Fan / Gas Mark 3)
325°F equals 165°C on a standard oven dial (exact 162.8°C), 145°C (300°F) in a fan-assisted convection oven, and UK Gas Mark 3, providing moderate domestic oven heat ideal for custard-based pies and dense pound cakes.
325°F is 163°C (use 160°C or 165°C on digital ovens). It is the premier temperature for rich butter cakes and custards where gentle heat transfer prevents dry outer rims.

Frequently Asked Questions
What is 325°F in Celsius and UK Gas Mark? ▾
325°F converts to 163°C (standard 160°C dial) or Gas Mark 3. For a fan-forced oven, set the dial to 140°C–145°C.
Why do some cake recipes call for 325°F instead of 350°F? ▾
Baking at 325°F produces flatter cake tops with minimal doming and keeps heavy batters (like pound cakes or banana breads) from browning before the center sets.
