Tests Per Million Calculator

How to Use the Calculator

1. Enter the total population size in the "Population Size" field.
2. Enter the total number of tests performed per year in the "Tests Per Year" field.
3. Click the "Calculate" button to compute the number of tests per million.
4. The result will be displayed in the "Result" section.

Working Principle

The Tests Per Million (TPM) is a measure used to express the frequency of tests relative to population size. It's commonly used in public health to standardize test frequency across different regions with varying population sizes.

The formula used is:

TPM = (Tests Per Year / Population Size) × 1,000,000

This formula helps in comparing the testing efforts between different regions or over time.

Example

For example, if a city with a population of 100,000 conducts 5,000 tests per year, the calculation would be:

TPM = (5,000 / 100,000) × 1,000,000 = 50,000

This means the city conducted 50,000 tests per million people that year.
