Plating, Anodizing & Surface Treatment calculator
Coating Weight Calculator
Estimate the mass of a solid coating from its area, mean thickness and density. Compare that deposit mass with available deposited material.
What this calculator does
- Estimate solid coating mass from coated area, mean thickness and deposit density.
Formula used
- Coating volume (cm³) = coated area (m²) × thickness (µm)
- Required mass (kg) = coating volume × density (g/cm³) ÷ 1,000
- Mass per area (g/m²) = thickness (µm) × density (g/cm³)
- Mass headroom = available deposit mass − required mass
Inputs explained
- Coated Area: Total area covered by this coating.
- Mean Coating Thickness: Planned mean solid coating thickness.
- Coating Density: Solid deposit density, not mixed bath density.
- Available Deposit Mass: Metal mass available as deposited coating.
How to use the result
- Best suited to deposit material planning, coating mass estimates.
- Excludes roughness, porosity and material lost in processing.
Current U.S. benchmarks
- The producer price index for industrial chemicals stands at 336.006 (BLS, Aug 2026), up 13.3% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- The U.S. has 14,543 chemical manufacturing establishments employing about 911,245 workers (Census County Business Patterns, 2023).
Common questions
- Does this include plating efficiency? No. It calculates material retained as coating. Estimate feedstock use and process losses separately.
- Which density should I use? Use finished deposit density from the material supplier or a matching measurement. Solution density describes a different material.
- Can I use nominal thickness? Yes for a planning estimate, if it represents the mean over the entered area. Local minimum specifications require separate verification.
- Why can coating volume equal area times thickness? The selected units make one square meter covered by one micrometer equal one cubic centimeter. Density then converts that volume to mass.
