In Indonesia especially the island of Java, many people use "Ons" that means 100 Grams. The unit used for rice, flour, eggs in small retail store.

My father said that the unit adapted from Dutch's metric system.

The pronunciation is the same to standard unit "Ounce" that I got confused when I first learn about units in elementary school.

The "metrification" of Dutch customary units is a fascinating subject on itself. The "ons" was in fact quite close to the ounce, but it was set to 100 grams during metrification. The step from 1 pound to 1 metric pound = 500g was less noticable.
