Wei

Wei is a traditional Chinese unit of measurement used to quantify weight, volume, or length, depending on the context. Historically, it helped standardize measurements across regions before modern systems like the metric system. Although the specific value of a wei can vary according to different measurement systems, it is often associated with the Chinese system and can be a small unit, such as a fraction of a more substantial measurement. Today, wei may also refer to a digital currency unit in blockchain technology, specifically in Ethereum, where one wei is the smallest denomination, similar to a cent in dollars.
