Poids et Mesures
Weights and Measures
A l'exception
des unités de mesure des terrains et de l'or, le système métrique est en vigueur
en Thaïlande.
When
you visit Thailand, you are unlikely to come across anything other than the
metric system when you go shopping. The exceptions to this are the measurements
used to describe land area and the weight of gold, which still use the old
Thai system..
