I noticed lots of people kindly converting °C to °F. But American standard baking and roasting temperatures occur in five degree increments. So I made this list of approximate conversions. These are not exact conversions, but they approximate common baking and roasting temperatures.
150°C is approximately 300°F
160°C is approximately 325°F
175°F is approximately 350°F
200°C is approximately 400° F
220°C is approximately 425°F
230°C is approximately 450°F
250°C is approximately 475°F
260°C is approximately 500°F
290°C is approximately 550°F
