  1. A kilogram is used everywhere to establish a uniform standard for measurement. When we buy goods, we expect a kilogram to represent the same amount globally, preventing confusion and ensuring fairness in international trade. Relying on agreed-upon international standards rather than local objects or opinions allows scientific results to be compared accurately and ensures that trade remains reliable, predictable and equitable for everyone across different regions.
