8.3453 pounds per cubic foot (another surfing photo)

Water weighs 8.3453 pounds per cubic foot. This surfer is in the middle of TONS of water. To give you an idea: A block of water 5'x5'x5' (5' cubic feet) weighs more than 1/2 a ton. Our Mother Ocean is very powerful indeed! A skilled surfer can negotiate the waves and safely play with the waves and not get injured. Often times they can dive below the churning whitewater while paddling out to the lineup. This photo is best viewed in download mode.

Terrific surfing image Brent and looks really super in download. But I must disagree with you on your weight of water. The number you cited, 8.3453, is actually the weight of 1 gallon of water. A cubic foot of liquid is equivalent to about 7.48 gallons, which leads to the figure of 62.4 lbs for the weight of 1 cubic foot of water. No offense intended, just reminded me of my years as a mechanical engineer.

Thank you tbell7D for the correction! You are absolutely right! Your correct math only shows that the water in a space of 5'x5'x5' (5 cubic feet of water) would weigh about 3.9 tons rather than close to 1/2 of a ton like I said. That is much more weight and more dangerous! (I hope I did the math right this time! lol)
Thanks for the "Terrific surfing image" comment and the nice compliment about the super download.

Wonderful photo whatever the math.
tbell7D was correct with his math. Instead of 8.3453 pounds per square foot it's closer to 62 pounds per square foot. That makes it MUCH more heavy water on the surfer! Thanks for the "wonderful photo" comment kpmac!

A block of water 5'x5'x5' is not five cubic feet. It is 125 cubic feet!
My bad! Once again I am incorrect ecblackiii. You are so right about the 5'x5'x5' being 125 cubic feet. I did do the math correctly about the weight of that block of water: It would weigh about 3.9 tons.....that is a lot of weight!

That much weight would break the back of my F-150!!
Well, the weight would not be all in one location, it would be spread around somewhat!

Alas, salt water, which the surfer is in, is heavier than fresh water and weighs ~64 lbs per cubic foot.
