## How to Use the Air Change Per Hour (ACH) Calculator

This ACH calculator helps determine the number of air changes per hour in a given room. Here’s how to use it:

- Enter the length of the room in meters.
- Enter the width of the room in meters.
- Enter the height of the room in meters.
- Enter the airflow in cubic meters per hour (m³/hr).
- Click on the “Calculate” button to get the results.

## How It Calculates

The ACH (Air Changes per Hour) is calculated using the following formula:

*ACH = (Airflow / Room Volume) * 60*

Where:

- Airflow is the measure of air moved through the room per hour (in cubic meters).
- Room Volume is computed by multiplying the room dimensions (in cubic meters).

## Limitations

This calculator assumes a perfectly sealed room with no additional sources of ventilation or air leakage. Real-world scenarios may involve additional factors that can influence effective air changes per hour, such as windows, doors, and other air exchange systems.
