Enter the total number of cigarettes smoked per day and the product of the number of cigarettes in a pack and the number of days in the period into the calculator to determine the packs per day. This calculator can also evaluate any of the variables given the others are known.

## Packs Per Day Formula

The following formula is used to calculate the number of packs smoked per day.

PPD = C / (N * P)

Variables:

• PPD is the packs per day C is the total number of cigarettes smoked per day N is the number of cigarettes in a pack P is the number of days in the period

To calculate the packs per day, divide the total number of cigarettes smoked per day by the product of the number of cigarettes in a pack and the number of days in the period.

## What is a Packs Per Day?

A Packs Per Day is a measurement used to quantify the amount of cigarettes a person smokes on a daily basis. It is often used in medical and health-related research to assess a person’s level of tobacco exposure. For example, if a person smokes one pack of cigarettes (typically containing 20 cigarettes) per day, they would be classified as a one pack-per-day smoker. This measure helps in determining the risk factor for various health conditions, including lung cancer and heart disease.

## How to Calculate Packs Per Day?

The following steps outline how to calculate the Packs Per Day (PPD).

1. First, determine the total number of cigarettes smoked per day (C).
2. Next, determine the number of cigarettes in a pack (N).
3. Next, determine the number of days in the period (P).
4. Finally, use the formula PPD = C / (N * P) to calculate the Packs Per Day.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

total number of cigarettes smoked per day (C) = 20

number of cigarettes in a pack (N) = 25

number of days in the period (P) = 7
