The length of a football field from goal line to goal line is around 300 feet, which is the equal of 100 yards. Three feet equals one yard. Given that a yard is 36 inches long, 100 yards is made up of 3,600 inches.
Inches, feet, and yards are standard length units in the United States, derived from the imperial system. The United States is the primary user of this system. The metric system measures length with millimetre, centimetre, and metre units. Because one yard is equal to 0.9144 metres, the metric equivalent of 100 yards is 91.44 metres.
