Explanation

Bar is a metric unit of pressure equal to 100,000 Pa (pascals). It is commonly used to express atmospheric pressure, where 1 bar is approximately equal to Earth's atmospheric pressure at sea level. It is not specifically for water pressure or buoyant force, though it can measure any pressure.
