# How much does sea water weigh per cubic foot?

The weight of sea water really depends on a number of variables, including the temperature, the amount of salt (salinity) and whatever other foreign items may be present, and the depth, thus the pressure. But to get to the basic answer, seawater, at the surface, on average weighs 1027 kg/m3, or just over 64.1 lbs per cubic foot.

-----------

The question is another way of asking for density of salt water. Salt water has greater density than that of fresh water, due to the dissolved salt. Fresh water has a density of 1000 kg/cubic meter vs. an average density of 1027 kg/cubic meter for ocean salt water.

## Related Questions That depends on how much of it you have!One pebble doesn't weigh very much, but a cubic foot of granite weighs 168 pounds! Compare that to water, which weighs about 62 pounds per cubic foot. the denisty of water is 1000 kilograms per cubic meter. since there are 0.3048 meters in every foot, and roughly .454 kilograms in every pound the conversion works out to 62.42796 pounds of water per every cubic foot so for 1 cubic foot of water there is 62.43 pounds. Once cubic foot of water weighs 62lbs water expands 4% when frozen, so..... one cubic foot of water becomes 1.04 cubic feet of ice, so..... one cubic foot of ice should weigh 59.52 lbs I surmized this by subtracting 4% from the weight of the water since 1.04 cubic feet of ice weighs the same as one cubic foot of water and because we only want the weight of one cubic foot of ice. 1water = 1.04Ice = 62lbs so (1.04Ice - 4%) = 1 Ice = 59.52 lbs Please, Check it yourself, I'm no mathematician.
