Introduction: Welcome to the Pack Year History Calculator, a tool designed to help estimate your pack year history based on your smoking habits. Pack years are a measure used in assessing the impact of smoking on health. This calculator provides a quick and simple way to determine your pack year history.
Formula: The calculator uses the formula: Pack Years = Packs per Day × Years Smoked. It multiplies the average number of packs smoked per day by the total number of years smoked to estimate the pack year history.
How to Use:
- Enter the average number of packs smoked per day in the "Packs per Day" field.
- Enter the total number of years smoked in the "Years Smoked" field.
- Click the "Calculate" button to obtain the estimated pack year history.
Example: For example, if someone smoked an average of 1.5 packs per day for 20 years, the calculator would estimate a pack year history of 30 pack-years.
