What is the mg/cm2 equivalent value for 0.05% lead by weight?

• A. 1.0 mg/cm2
• B. 0.5 mg/cm2
• C. 0.1 mg/cm2
• D. 2.0 mg/cm2

Answer: (A)

mg/cm2 equivalent value converts how much lead is present by weight on a surface into an area-based loading. It uses a standard reference scenario so you can compare lead loading across surfaces. For 0.05% lead by weight, the established conversion used in this context maps directly to 1 mg of lead per square centimeter. This makes the 1.0 mg/cm2 value the correct match for that weight percent, which is why it’s the right choice. The other numbers correspond to different weight-percent conversions within the same scheme, so they don’t fit this specific mapping.
