What is the weight of freshwater per cubic foot?

The weight of freshwater per cubic foot is approximately 62.4 pounds. This figure is significant in various aquatic activities, including scuba diving, because it helps divers understand buoyancy and the physical properties of water. Freshwater's weight is crucial for calculating the buoyant force acting on a diver or an object submerged in water, which directly affects how a diver manages their buoyancy and flotation during a dive.

In contrast, the other values presented do not accurately represent the weight of freshwater. A figure such as 50 pounds would underestimate the weight of freshwater, leading to incorrect assumptions about buoyancy and weight distribution. Similarly, values like 70 and 75 pounds exceed the accepted standard for freshwater, which can mislead a diver in understanding the forces they may encounter underwater. Recognizing the accurate weight of freshwater facilitates better planning and safety while diving.
