This is not really accurate.
Old Toasters used to have a bimetallic strip that would bend as heated and the dial moved this distance the strip was from the contact. So the further the distance the higher the temp.
Modern toasters will measure the charge in a capacitor so this acts like a timer but isn’t directly correlated with minutes. As you increase the number it increases the voltage setting on the capacitor. This may or may not be linear.
Some more expensive toasters have a timing circuit.
