Ahm

1

In Denmark, a unit of liquid capacity used for Rhine wine, linseed oil and vinegar, = 4 ankre = 2/3 oksehoved.

According to the decree of 1698, 1 ahm = 155 potter. But the same decree says there are 39 potter to the anker, making 156 potter to the ahm. Friss and Glaman (page 119) say that “actual evidence ... seems to indicate the greater likelihood that in practice the ahm contained 160 potter”. If that is so, the ahm was about 154.9 liters. Some sources say 154.579.

L'Aem est compté audit Amsterdam pour 8 Steckans ou pour 20 Verges, ou Viertels, ou bien pour la sixiéme partie d'un Tonneau de 2 Pipes, ou de 4 Bariques de France, ou de Bourdeaux, lequel sixiéme l'on nomme audit Bourdeaux Tierçon, parce que les trois sont 1 Pipe, ou 2 Bariques, & les 6 sont le susdit Tonneau.

The ahm is reckoned in Amsterdam for 8 steckans or 20 verges or viertels, or for a sixth of a tonneau of 2 pipes, or for 4 barriques of France, or of Bordeaux, which sixth part [of a tonneau] is called a tierçon in Bordeaux; because three [ahm] make 1 pipe or 2 barriques, and 6 make the aforementioned tonneau.
