Poppyseed

Poppyseed , also called P (p) oppy seed in the literature , is one of the smallest linear measures in the Anglo-American system of measurement . The measure is derived from the poppy seed . The hair width was set equal to the line / line .

A dimensional chain looks something like this:

• 12 widths of human hair = 1 poppyseed / poppy seed
  • 4 poppyseed = 1 Barleycorn / barley grain
    • 3 barleycorn (lengthways) = 1 inch / inch
      • 12 inches = 1 foot
        • 3 feet = 1 yard

Calculated in practical lengths:

• 1 poppyseed = 1 line = 0.00212 meters = 0.00694 feet (US) = ¼ barleycorn (rarely 1/5) = 1/12 inch
  • 1 barleycorn = 0.00847 meters = 0.0278 feet (US) = 1/3 inch
