Frigidaire ovens typically display temperatures in Fahrenheit, which is the standard unit of temperature measurement used in the United States. Most household ovens in the US, including those manufactured by Frigidaire, are calibrated to display temperatures in Fahrenheit.
However, it's essential to check the specific model and user manual of the Frigidaire oven you have or are considering purchasing, as appliance specifications can vary, and there may be newer models or international versions that offer temperature display options in Celsius or other units. The user manual will provide detailed information about the oven's features and how to navigate its settings, including temperature units.
