A Mayan unit of mass, estimated by Calderon at 43.4 kilograms. It is often said that there were no units of mass in Central America prior to the Spanish invasion. Apparently balances, steelyards, etc. were unknown, as were mass standards, but there were words like this one associated with a practical value of mass in a particular application.
