A long time ago a king wanted to see how long his foot was. His foot was exactly 12 feet long so he called that a foot.

To measure a foot length you could use a ruler, a yard stick, a tape measure, or any object that you knew was precisely one foot long on a side or edge.
To calculate running feet, simply measure the length of an object in feet. If the object has a width, multiply the width by the length to get the total square footage, then divide by the width to get the running feet. For example, a 10 ft long object with a width of 2 ft would be 20 running feet.

Yes, the right foot is a chiral object because it cannot be superimposed onto its mirror image, the left foot. This means that the right foot and left foot are non-superimposable mirror images of each other, making them chiral.
