## Tests Per Million Formula

TPM = T / P * 1000000

Variables:

- TPM is the Tests Per Million (tests/million people)
- T is the number of tests
- P is the available population

To calculate Tests Per Million, divide the number of tests by the available population then multiply by 1,000,000.

## How to Calculate Tests Per Million?

The following steps outline how to calculate the Tests Per Million.

- First, determine the number of tests.
- Next, determine the available population.
- Next, gather the formula from above = TPM = T / P * 1000000.
- Finally, calculate the Tests Per Million.
- 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.

number of tests = 34

available population = 1200
