Length (centimeter) x Width (centimeter) x Height (centimeter) / 1,000,000 = Length meter x Width meter x Height meter = Cubic meter (m3) . e.g. 35 cm x 35 cm x 45 cm = 0.055 cbm. CFT Formula : Length" x Width" x Height" = ? divided 1728 = Cubic feet (CFT) KT Formula : Pounds divided by 2204.62 = Kiloton (Kt)
