Across the world, Khanchai (ขรรค์ชัย 
, Khanchai 
, ขันชัย ) is quite a rare principally masculine, but very seldom girly given name. The forename Khanchai is characteristic of South-eastern Asia, particularly Thailand, where it is quite a rare primarily male, but scarcely girly name. Very seldom, Khanchai is the last name as well as the forename.
