What branch creates standard weights and measures?

The branch responsible for creating standard weights and measures is typically a national standards organization or a government agency. In the United States, this role is fulfilled by the National Institute of Standards and Technology (NIST). Internationally, the International System of Units (SI) provides a framework for standardization, with the International Bureau of Weights and Measures (BIPM) overseeing global standards. These organizations work to ensure consistency and accuracy in measurements across various fields.
