Determining Your Pack Year
Individuals can determine their pack-years by multiplying the number of years they smoked by the number of packs they smoked per day. For example:

2 packs per day for 5 years = 10 pack-years

1 pack per day for 10 years = 10 pack-years

A person reaches 30 pack-years of smoking history by smoking a pack a day for 30 years or two packs a day for 15 years and so on.
