In this post, we will see the book Units Of Measurements Of Physical Quantities by A. G. Chertov.

# About the book

UNITS OF MEASUREMENT OF PHYSICAL QUANTITIES is a unique and convenient volume that will be of equal interest as a textbook to the advanced high school student and graduate physics or engineering major, or as a reference volume to the teacher as well as the practicing physicist, chemist, engineer, or laboratory and industrial technician. The coverage combines treatment of units, dimensional analysis, and good physics and provides a fundamental contribution to the subject. The author takes nothing for granted; every step is explicitly explained by proof and derivation. Although the subject of units of physical quantities is usually touched upon in fundamental textbooks on physics, chemistry, or engineering, and while most handbooks contain a small section devoted to this topic accompanied by a number of numerical conversion tables, no work equivalent to this one exists in the English language.

The book was translated from Russian by was published in by Publishers.
