When talking about diving, what measurement is commonly used to define depth underwater?

In underwater diving, depth can be measured in different units depending on the region and diving community. Both feet and meters are commonly used to define depth. In some places, especially in the United States, feet are the standard unit of measurement, while in many other countries, including those that follow the metric system, depth is often expressed in meters.

The use of both feet and meters as acceptable measurements allows divers from various backgrounds to communicate effectively and ensure safety. For instance, dive tables and dive computers may provide information in one or both units, catering to a diverse range of divers. This flexibility in measurements is essential for operational consistency and safety in diving practices across different regions and settings.
