Important Note on Numbering Systems

Historically, Vietnamese used two different numbering scales. The modern standard follows the "short scale" (used in the US and most English-speaking countries), where: * Triệu = Million (1,000,000) * Tỷ = Billion (1,000,000,000)

The older "long scale" (used in some European countries) is now largely obsolete in Vietnamese but may appear in older texts. In that system, "tỷ" could sometimes refer to a "milliard" (10⁹), and "triệu triệu" (million million) referred to 10¹². For clarity, the modern meaning of "tỷ" = 1,000,000,000 (billion) is definitive.
