Khetha ho latela maemo a tloaelehileng:
Chaena (GB) → botsho (metsi a ntshang metsi), bofubedu (ho tima mollo), botala (metsi a nooang)
Yuropa le United States (AWWA/EN) → botsho (bo thibelang mafome ka ntle), botala/boputsoa (lesela)
Japane (JIS) → botsho (lebota le ka ntle), bofubedu (ho tima mollo)
