Understanding Pounds and Metric Tons
The kilogram is the SI base unit of mass and the reference point for the entire metric system. Pounds and ounces dominate in the United States, while stones remain common for body weight in the UK and Ireland. Metric tons (1,000 kg) and US tons (2,000 lb) appear in freight, agriculture, and industry — and because they differ by about 10%, confusing them is a frequent and costly mistake.
