Rock Density Calculator

Got a core sample and need its bulk density, porosity, and specific gravity fast? No lab spreadsheet handy? This app gives you instant results from dry, saturated, and submerged mass measurements or look up typical values for common rock types. CALCULATOR MODE: Enter dry mass, saturated mass, and submerged mass. Get bulk density, grain density, porosity, void ratio, water absorption, and specific gravity. REFERENCE MODE: Look up typical density, porosity, and specific gravity for 13 rock types including granite, basalt, limestone, sandstone, shale, quartzite, marble, gneiss, slate, dolomite, chalk, conglomerate, and obsidian. WHAT IT CALCULATES: - Bulk density and grain density - Total porosity and void ratio - Water absorption percentage - Specific gravity KEY FEATURES: - Lab measurement calculator - 13 rock type reference database - Metric and imperial units - Works completely offline - No account or login required Built for geologists, mining engineers, petroleum engineers, and lab technicians.
