2x4x8/144 = 0.4444 0.444 x 62.4 x .85 ~23.6 lbs
That depends what "unit" you are talking about.
A unit of time cannot be compared to a unit of length.
Meter is a unit of length. Milliliter is a unit of volume.
Square foot unit is the unit area. The unit is inches. These two are not comparable.

About 10 pounds.
A 2x4x8 spruce pressure-treated lumber typically weighs around 18-20 pounds. The weight can vary slightly depending on the specific moisture content and density of the wood.
The real measurement for 2 by 4 by 8 is 64. This is a math problem.
80 for your studs, using the same for plates? If so, add the full linear footage for your rim and header, ALL around the building.
A 2x4x8' metal stud typically weighs around 7-10 pounds, depending on the type of metal used and any additional coatings or treatments applied to it.
You can get more insulation when using 2x6 studs rather than 2x4 studs
To determine how many 2x4x8 boards you need for an 8-foot wall, you first need to know the spacing of the studs. Typically, studs are placed 16 inches apart on center. An 8-foot wall requires approximately six studs (including one at each end), so you would need about 6 boards, assuming you are using the entire length of each board for the wall studs. Additionally, you may need extra boards for top and bottom plates, so it's wise to purchase a few more.
A unit of what?
Nothing. A 2x4 laid flat and supported on its ends that are 8 feet apart cannot even support its own weight.
