Nail (unit)
A nail, when used as a unit, is usually one sixteenth of a certain base unit. In English usage the most common base units were the foot and the yard for length, the acre for area and the (long) hundredweight for mass.
| Base unit | Equivalent | Metric |
|---|---|---|
| foot | 1 digit | = 1.905 cm |
| yard | 21/4 inches | = 5.715 cm |
| acre | 1/4 rood | = 252.9285264 m2 |
| hundredweight | 1 clove = 7 pounds | = 3.17514659 kg |
(Metric sizes calculated for most common values of the base units today.)
