In the New Kingdom of ancient Egypt, introduced 12th – 18th Dynasties to ?, a unit of mass = ¹⁄₁₀ dbn, about 9.0 to 9.5 grams. Filling in the vowels, it is often spelled “qedet” or “kedet”. In 19th century scholarship it was called a kat. Often called the “kite”.



The weights of the kedet unit range from 8.812 grammes (136 grains) (fixed by Petrie as the lowest limit) to 10.108 grammes (156 grains). This gives an average weight of 9.460 grammes or 146 grains.

[Describing a histogram] Les “pics” correspondent à des valeurs qui ont entre elles des rapports entiers; si l'on prend la valeur de 9 g-9.5 g indiquée par l'un des “pics” les plus nets, valeur reconnue du kdt, on peut dresser le tableau suivant. [table omitted here]

Une grande partie des poids se classe donc dans des tranches de valeur qui sont en rapport entier avec une unité située entre 9 g et 9.5 g.

The peaks correspond to values which are related by integer ratios; if we take the value of 9 - 9.5 grams indicated by the clearest peak, a value recognized as the kdt, we may construct the following table: [table omitted]

A large part of the weights thus classified into grpous a value which is a integer multiples multiple of a unit situated between 9 grams and 9.5 grams.
