The inch is a unit of length in the imperial and US customary systems, defined exactly as 2.54 centimeters since the International Yard and Pound Agreement of 1959. It is divided into binary fractions — halves, quarters, eighths, and sixteenths — and remains standard for screen sizes, display resolutions, and construction lumber in the United States. Historically, the inch derived from the width of a human thumb or three barleycorns placed end to end. A US letter sheet of paper measures 8.5 inches wide.
