Convert from nook to stremma

Unit Definition (nook)
The nook is a traditional unit of land area in northern England. Originally the nook was 1/2 virgate; a virgate, often called a yardland in the north, was about 30 acres in southern England but tended to be closer to 40 acres in the north. A nook of land thus came to be 20 acres or about 8.094 hectares.

Unit Definition (stremma)
The stremma is a traditional Greek unit of area, now redefined to equal exactly 1000 square meters or 0.1 hectare (0.24710 acre).
