6yd 9ft 4in times 2 equals

It would be better to convert each measurement into its smallest measure. In this case let us convert yards and feet into inches.

1 yard = 36 inches

1 foot = 12 inches

6 yards = 216 inches

9 feet = 108 inches

216 inches + 108 inches + 4 inches = 328 inches

328 inches * 2 = 656 inches

656 inches / 36 = 18.22

18 * 36 = 648 inches is equivalent to 18 yards.

656 - 648 = 8 inches.

6yd 9ft 4in times 2 equals 18 yards and 8 inches.
