According to Jeff Dean on Twitter, only the US, Liberia, and Myanmar use non-metric measurement systems, which has significant implications for AI development in terms of data localization and model adaptation (source: Jeff Dean, Twitter). For AI companies, understanding these regional standards is crucial when training language models or deploying AI-driven platforms that interact with localized data inputs. This highlights the need for robust localization strategies and flexible data pipelines to ensure accuracy and user relevance when expanding AI products globally.
