How much time does convection oven save?

Convection ovens reduce cooking time by 25%-30% as compared to the traditional bake. They are able to do this as compared to conventional heat methods that use still, radiated heat, convection baking makes food crisp up outside yet keep an ideal moist centre because hot, dry air circulates within the oven and quickly removes the moist air that forms over food surfaces to slow food from finishing.
