A simple measurement conversion utility.

The unica was one-twelfth of a Roman foot. In 1324 the legal definition of the inch was set out in a statute of Edward II of England, defining it as “three grains of barley, dry and round, placed end to end, lengthwise”. At various times the inch has also been defined as the combined lengths of 12 poppyseeds. Since 1959 the inch has been defined officially as 2.54cm.
