Distance

The Hort
1 1/4 inches

The hort is approximately and inch and a quarter in length.
---Tribesmen of Gor, p 49

The Foot
The Gorean foot is equivalent to 10 horts, approxiamtely 12 1/2 earth inches

The Gorean foot is, in my estimation, just slightly longer than the Earth foot; based on the supposition that each of its ten horts is roughly one and one-quarter inches long.
---Raiders of Gor, p 127

The Pasang

The pasang is a measure of distance on Gor, equivalent approximately to 0.7 of a mile.
---Tarnsman of Gor, p 58

Length

The Ah-il and Ah-ral
Measures used in the sale and use of cloth.

Cloth is measured in the ah-il, which is the length from the elbow to the tip of the middle finger, and the ah-ral, which is ten ah-ils.
---Tribesmen of Gor, p 50

Volume

The Gill
Measures liquids.

In a matter of perhaps two or three seconds, it had drawn perhaps a gill of liquid.
--- Outlaw of Gor, p 34

The Tef
Basically the equivalent of a fistfull.

The Tefa
6 Tefs

The Huda
5 Tefa

A handful with the five fingers closed, not open, is a tef. Six such handfuls constitute a tefa, which is a tiny basket. Five such baskets constitute a huda.
---Tribesmen of Gor, p 46

Weight

The Stone
The basic unit of weight, equivalent to 4 Earth pounds.

I have calculated this from the Weight, a Gorean unit of measurement based on the Stone, which is about four Earth pounds.
---Raiders of Gor, p 127

The Weight
10 Stones

A given tree, annually, yields between one and five Gorean weights of fruit. A weight is some ten stone, or some forty Earth pounds.
---Tribesmen of Gor, p 37

I have calculated this from the Weight, a Gorean unit of measurement based on the Stone, which is about four Earth pounds. A Weight is ten Stone.
