150 inch refers to the diagonal. 150 inch. Converted into meters, it is 3.8 meters. If the square is about 3.2m x 3.2m and the screen is 150 inch, the ratio is 16: 9:

Length = diagonal X 0.87 16

Width = diagonal X 0.4903

150 inch screen,

Length =150x0.8716 =130.74 inches =? 130.74x2.54 = 332.08 (cm) = 3.3208m.

Width = 150 X 0.4903 = 73.55 inches = 73.55x2.54 =186.80 (cm) =1.868m.

Extended data

Diagonal, a geometric term, is defined as a line segment connecting two nonadjacent vertices of a polygon, or a line segment connecting any two vertices of a polyhedron that are not on the same plane. In addition, in algebra, n-order determinant, the numbers from upper left to lower right belong to the main diagonal, and the numbers from upper left to upper right belong to the sub-diagonal.

Calculation method of size:

1、 16:9:

Length = diagonal X 0.87 16, width = diagonal X 0.4903.

For example: 100 inch screen, length =100x0.8716 = 87.16 inch = 87.16x2.54 = 221.39 (cm
