Gorean Measurements

 DISTANCES

1 HORT = 1 and 1/4 inches = 3.2 centimetres (approx)

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

1 GOREAN FOOT (10horts) = 12 and 1/2 inches = 32 cm (approx)

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

1 AH-IL = 18 inches (approx) = 46.15 cm (approx)

1 AH-RAL (10 ah-il) = 180 inches (approx 15ft) = 461.5 cm (approx 5m)

1 PASANG = 1/7th of a mile(3,696 US ft) = 1.2 km (approx 1232m)

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

Hand, as height: a measurement of height, primarily of kaiila. Both the Wagon People's kaiila and the sand kaiila of the Tahari stand about twenty to twenty-two hands at the shoulder.

WEIGHT/MASS

1 GOREAN STONE = 4 US pounds = 1.8 kilograms (approx)

1 GOREAN WEIGHT (10 stone) = 40 US pounds = 18.14 kg (approx)

LIQUID VOLUME

1 TALU = 2 US gallons = 7.5 litres (approx)

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

SOLID VOLUME

The following measurements are "trade weights," meaning that they are, like the ah-il, variable according to the hand size of the measurer. Nevertheless, due to their ease of use, they are retained by the Goreans as practical ways to measure solid volume in a distributary environment, particularly in trade-based Gorean settings where standardised measurements are not available for handy measurement:

1 TEF = a closed handful of whatever produce (such as dates) is being weighed. 6 tefs equals one "tefa."

1 TEFA = 6 tefs (or closed handfuls), or roughly the amount of merchandise it would take to fill a small basket. 5 tefas equal 1 "huda."

1 HUDA = 5 tefa, or small baskets full.

In addition, it only stands to reason that Goreans would also rely upon the "squared measure" of their distance units in measuring solid mass as well as space. The use of the Gorean "square foot" is highly likely, as is the "square hort," the "square ah-il" and "square ah-ral," and the "square pasang."

The Stone

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

The Weight
10 Stones

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.
