Khaset was one of the 20 nomes in Lower Egypt and had district number 6.
The area of the district is not readable, usually the nomes were about 30-40 km (18-24 miles) in length and their area depending on the depth of the Nile valley and the beginning of the desert. The area was calculated in cha-ta (1 cha-ta equals roughly 2,75 hectare / 2.4 acres) and the distance was calculated in iteru (1 iteru equals roughly 10,5 km / 6.2 miles) in length. 
The Niwt (main city) was Khasu/Xois (part of modern Sakha) and among other cities were Per-Wadjet/Buto (modern Tell el-Farain). Per-Wadjet was sometimes also part of the Sap-Meh nome.
