As you might expect, the toaster can get pretty hot, reaching temperatures of up to 350 degrees Fahrenheit or 176 degrees Celsius. This heat is necessary to bake the bread and give the outside toast that perfect crispiness. The time it takes for a toaster to reach this high temperature depends on the wattage of the toaster. The higher the power, the more powerful the toaster, and the less time it takes to get the delicious result.
