Measurement Units - YAML

Measurement units are standards for expressing physical quantities numerically. Various systems exist, including the International System of Units (SI), the Imperial/US customary system, and Shakkanho (Japanese traditional units). The SI system is used as the global standard in scientific and engineering fields, the Imperial/US customary system is primarily used in daily life in the United States, and Shakkanho consists of Japanese traditional units, some of which are still used conventionally today.
