Barnes often uses both kN/m³, kPa, and sometimes t/m². An on‑PDF unit converter would help with the geotechnical formulas.
The textbook covers essential geotechnical engineering topics across 14-15 chapters, including soil composition, classification, and permeability. Key areas focus on effective stress, compressibility, consolidation, and shear strength, with detailed methods for analyzing foundation stability and settlement. Later chapters address design, slope stability, earthworks, and site investigation, with the 4th edition incorporating Eurocode standards.
