Engineering Dimensions, Units, and Conversions
暫譯: 工程維度、單位與轉換

《工程維度、單位與轉換》深入探討了工程實務中維度、單位及單位轉換的分析與應用。它展示了維度同質性和單位一致性的重要性。

本書全面探索了主要和次要單位，詳細描述了英制系統和國際單位制（SI）中的各種單位系統。它提供了轉換比率的見解，並介紹了基於軟體的方法論。本書還檢視了圖紙中的標註，包括標註基礎知識和多個物件及系統標註的練習。本書將成為從事工程研究與開發的實務工程師和研究人員的重要參考資料，對於工程學科的本科生和研究生也將具有吸引力。

Yongjian Gu received his M.Sc. and Ph.D. degrees in mechanical engineering from the State University of New York (SUNY) at Stony Brook. He is a professor at the U.S. Merchant Marine Academy (USMMA) and an adjunct at the New York Institute of Technology (NYIT). He teaches thermal fluids, total energy systems and design, propulsions, steam turbine and components, gas turbine and auxiliary equipment, engineering economics, and other courses to undergraduates and graduate students. He gives review and practice workshops of the Fundamentals of Engineering (FE) exam in the mechanical discipline. He holds a license as a registered Professional Engineer (P.E.) in the state of New York. He also holds a certificate as a professional Oracle Database Administrator (DBA). Prior to teaching in academic institutions, he worked at industrial corporations, consulting firms, and the U.S. Department of Energy's national laboratory as a senior mechanical engineer, a project engineer, and a lead engineer for many years. He has rich and valuable academic and professional experiences in HVAC system, piping systems, thermal energy systems, and renewable/ sustainable energy applications. He is very knowledgeable about dimensions, units, and unit conversion in engineering. He is actively involved in engineering research and development and academic activities. He has many publications in his subject areas of teaching and professional expertise. He serves as a peer reviewer for multiple scientific and technical journals. He also sits on several professional boards and conference committees.
