One long ton equals exactly 35,840 avoirdupois ounces. This is because 1 long ton = 2,240 pounds, and 1 pound = 16 ounces, so 2,240 × 16 = 35,840 ounces. If dealing with precious metals, note that 1 long ton = approximately 32,150.75 troy ounces, which is different because troy ounces use a different pound weight (troy pound = 12 troy ounces, not 16 avoirdupois ounces).

Historical trade routes and imperial standardization created regional preferences. The British Empire standardized the long ton (2,240 pounds) across its territories, which is why UK, Australia, India, and Commonwealth nations use it. The United States adopted the short ton (2,000 pounds) for domestic commerce in the 1800s. Modern international maritime law recognizes both, but contracts must explicitly specify which is used to avoid 10% discrepancies in billing and customs calculations.
