The value watts/square foot (W/ft2) is a value of "energy density" for solar panels, indicating their peak power output. Mass-produced solar panels are currently producing up to 13 W/ft2 or about 140 W/m2.
The SI unit watts/square meter (W/m2) is also the unit of solar irradiance, which measures the energy received by a surface exposed to sunlight. The average solar radiation received at Earth's surface is about 342 W/m2 and the maximum is about 1000 W/m2.
No, a foot is a unit of length equal to 12 inches, whereas a square foot is a unit of area equal to a square with sides of 1 foot in length. A square foot is the area of a square that measures one foot on each side.
A square foot is a common American unit of measurement. A square foot is equal to 144 square inches.
A square foot is a unit of area, not length. Since a square foot is 12 inches by 12 inches, that means it is 144 square inches.
A square foot is a unit of area. A yard is a unit of distance. The two units are therefore incompatible.
A square foot is a unit of area. A metre is a unit of length. The two units are therefore incompatible.
A square foot is a unit of area. A metre is a unit of length. The two units are therefore incompatible.
'square feet' and' feet' are units of two different properties and cannot be compared. A length can be expressed in feet [ft]. An area can be expressed in square feet [ft^2]. For example, a square has 4 edges of length 1 foot. The area of the square = 1 ft * 1 ft = 1 ft^2 or 1 square foot.
A foot is a unit of length. A square foot is a unit of area. The two units are therefore incompatible.
A metre is a unit of distance. A square foot is a unit of area. The two units are therefore incompatible.

None. Watts is unit of power. Square meter is unit of area.
