Convert from football field [U.S., complete] to angstrom

Unit Definition (football field [U.S., complete])
The football field is a common informal unit of distance in the United States and Canada. Americans aren't quite agreed as to whether the unit is exactly 100 yards (91.44 meters), the distance between the goal lines on an American football field, or 120 yards (109.728 meters), the 'complete' distance including the two end zones. Canadian football fields are 110 yards (100.58 meters) long between the goal lines and 150 yards (137.16 meters) including the end zones. The football field is also used sometimes as an informal unit of area: including the end zones, an American football field represents an area of 1.3223 acre or about 0.535 hectare while the Canadian football field has an area of 2.0145 acre or 0.815 hectare.

Unit Definition (angstrom)
The Angstrom is a metric unit of length, equal to 0.1 nanometer or 10e-10 meter. Angstroms are most often used to measure the wavelength of light and are commonly used by chemists and physicists in the field of spectroscopy. One of the pioneers of spectroscopy was the Swedish physicist Anders Jon Ångström (1814-1874), after whom the unit is named.
