Regardless of how you configure units on an ECDIS, ENC sounding data is always expressed in which unit?

Explanation:
The depth values in ENC data are stored in meters. This follows hydrographic data standards that use metres as the base unit for sounding. The ECDIS can display depth in other units (like feet) by converting the underlying metre values for display, but the actual ENC sounding data remains in metres. So, while you can view the depth in different units, the true data is expressed in metres. Nautical miles relate to horizontal distance, and centimeters are not the standard unit for ENC soundings.
