Use the conversion factor that 1 yard is equal to 3 feet.

51ft

Practice makes perfect

To convert yards (yd) to feet (ft) we need to create a conversion factor. We know that there are 3 feet in 1 yard, which means we have the following conversion factor. 3 ft/1 yd Multiplying 17 yards by this conversion factor will convert it to feet.

17 yd* 3 ft/1 yd
