Note 203 — Chapter V · Magic Rites connected with the Several Departments of Nature (continued 2)
Reading edition
A koyan, as a measure of weight, contains 40 pikuls = 5333⅓ lbs.
Rather over 20 gallons (gantang) of rice (padi) go to a pikul.
The term koyan is also used as a measure of capacity, in which sense it contains 800 gantangs.
The term gantang has been rendered here by “gallon,” of which it is at present the legal equivalent, but the native gantang had a standard varying according to locality. ↑
