Used to expresses habitual past actions and is followed by the simple form of a verb, while be used to expresses being accustomed to something and is followed by a gerund. The document provides examples to illustrate the difference, showing that "I used to walk to work" refers to a past habit but "I am used to walking to work" refers to a current normal activity. Care must be taken with these similar but differently used structures.
