Convert from livre [France] to pfund [Denmark, Germany]

Unit Definition (livre [France])
The livre is a traditional unit of weight in French speaking countries and in Greece. The livre corresponds to the English pound and to the Spanish libra. The livre is divided into 2 marcs or into 16 onces. The French livre varied from market to market, but the official standard from about 1350 to the introduction of the metric system was the livre poids de marc or livre de Paris of 489.5 grams (1.079 English pounds). In modern France, the livre is used as an informal metric unit equal to exactly 500 grams or 0.5 kilogram (1.1023 pounds). The traditional Greek livre is also about 500 grams.

Unit Definition (pfund [Denmark, Germany])
The pfund is a traditional German weight unit corresponding to the English pound. The pfund is equal to 16 unze or 32 lot. Traditionally the pfund varied in size from market to market, and the various German states adopted different standards, ranging from something close to the English pound (454 grams) to the Viennese pfund at about 1.2 pounds (560 grams). When Germany was unified in the late nineteenth century, the pfund was redefined as a metric unit equal to exactly 500 grams (about 1.102 31 pound).
