Abstract
A system and methods for unit of measurement conversion and search query expansion are described. The search query expansion may include identifying an initial unit of measurement associated with a property and an initial numeric value for the initial unit of measurement within a search query, automatically forming an expanded search query by expanding the search query to include at least one related unit of measurement associated with the property, and sending the expanded search query to a search engine to search a database. Other embodiments are described and claimed.
