Calculator

This calculator helps to produce a numerical value of lifetime tobacco exposure called pack years. A pack year is defined as twenty cigarettes smoked everyday for one year. People who smoke often vary their smoking habits over the years which can make it difficult to create a pack score. This smoking pack year calculator simplifies the task.
