Magnet Weight Calculator

Calculate magnet weight fast. Block, cylinder, ring & custom shapes. NdFeB, ferrite, SmCo built in. Customize densities. Fully offline. For magnet pros.

Magnet Weight Calculator (MagCal) is a practical tool built for the magnet industry. Quickly estimate magnet weight and volume from product dimensions and material density — ideal for quoting, incoming inspection, and production planning.

KEY FEATURES • One-tap calculation: Select material and shape, enter dimensions (mm), get weight (g) and volume (mm³) instantly • Multiple shapes: Block, Cylinder, Ring, and Custom for complex geometries • Built-in materials: Sintered NdFeB, Bonded NdFeB, SmCo, Ferrite, Alnico, FeCrCo and more • Customizable parameters: Add, edit, or remove materials and densities to match your grades and processes • Fully offline: All calculations run locally on your device — no internet required

CALCULATION METHODS • Block: Volume = Length × Width × Height • Cylinder: Volume = π × Radius² × Height • Ring: Volume = π × (Outer Radius² − Inner Radius²) × Height • Custom: Enter product volume directly • Weight = Volume × Density ÷ 1000, displayed to 4 decimal places

WHO IT'S FOR Magnet sales teams, procurement staff, QC inspectors, product engineers, and manufacturing technicians.
