1 foot = 12 inches = 304.8 mm. So 1 square foot = 304.8 x 304.8 = 92,903 sq mm. 6 sq ft = 557,418 sq mm
1 acre = 43,560 square feet
Approximately 1.5 pounds (1 1/2). ( I said approximately as there are many kinds of plywoods of different densities)
Exactly 1.

1 foot = 12 inches = 304.8 mm. So 1 square foot = 304.8 x 304.8 = 92,903 sq mm. 6 sq ft = 557,418 sq mm
92903.04 square mm
1 millimeter is 0.0032808 feet.
mm (millimeter) is a unit of length. Acre is a unit of area. 1 acre = 43560 ft2 (square feet) = 4046.86 m2 (square meters) 4.04686 x 109 mm2 (square millimeters)
1 mm = 0.00328 feet so 30 mm = 30*0.00328 feet = 0.0984 feet
1000 mm x 1000 mm = 1,000,000 mm2 = 1 square meter
25.4 mm = 1 inch 700 mm = 27.559 inches = 2.297 feet

Ex: Length 1000 mm Width 500 mm Square feet=(Length*Width)/90000 ( (1 Sqft=(300*300)mm=90000mm) =(1000*500) /90000 Answer = 5.55 sqft
1 cm = 10 mm so 1 sq cm = 1 cm * 1 cm = 10 mm * 10 mm = 100 sq mm.
One meter has 1000 mm.1000 mm times 1000 mm is equal to 1 000 000 square mm.
