Using the Calculator
To use the smoking pack years calculator enter a value for each of the types of tobacco smoked and the period of years over which the quantity you have entered was smoked.
Once you have entered all the values click the Calculate button to calculate the total smoking load and the pack years value.
Once the calculation has been made you can either amend the numbers you have entered or click the Reset button to reset the calculator.
Please note that whilst most of the values should be specified as number smoked per day, tobacco should be specified as amount smoked per week.
You can create a shortcut to the calculator on your desktop by first visiting the homepage, then reduce the size of the browser window screen by clicking on the icon "restore down" top right, then, press your left mouse button down on the calculator icon in the address bar and drag the icon onto your desktop whilst still holding the button down.

You can access the calculator by clicking on the icon and it can then be minimised to your tool bar and used as needed throughout the day.
