إن Corrosion Rate Calculator is a practical online tool designed to help engineers, researchers, and metalworking professionals accurately calculate metal corrosion rates. By entering weight loss, material density, exposed surface area, and exposure time, users can quickly determine corrosion rates in mm/year, MPY, and other units. This free calculator simplifies corrosion analysis, supports material performance evaluation, and helps assess the durability of metals in various industrial environments. Ideal for corrosion testing, metal fabrication, pipeline maintenance, and industrial engineering applications.

Weight loss

Enter the measured mass loss directly, or enter the specimen weight before and after exposure (after cleaning).

Weight input mode

Material density

Preset densities are approximate reference values. Use the measured or specified density of your alloy when known; editing the density switches the material to Custom.

Surface area and exposure time

Total area in contact with the environment, including edges.
1 year = 365 days = 8,760 hours.
