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
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
