The Galvanized Common Nails Per Pound calculator computes the number of galvanized common nails based on the nail size and a weight of nails .
INSTRUCTIONS: Choose units and enter the following:
- (NS) Nail Size (choose: 2d, 3d, 4d, 5d, 6d, 7d, 8d, 10d, 12d, 16d, 20d, 30d, 40d, 50d, 60d)
- (NW) Weight of Galvanized Common Nails
Galvanized Common Nails Per Pound (nN): The calculator returns the number of nails of that size equal to the specified weight.
The Math / Science
The Galvanized Common Nails Per Pound equation computes the weight of the nails as follows:
nN = NW / WPN
where:
- nN = Number of Nails
- NW = Weight of the Nails
- WPN = Weight per Nail

Nails are galvanized to protect them from rust and corrosion. The process involves coating the nails with a layer of zinc, which acts as a barrier against moisture and other elements that can cause rusting.
Why Galvanize Nails?
- Rust Resistance: Zinc prevents the steel underneath from coming into direct contact with moisture and oxygen, which cause rust.
- Durability: Galvanized nails last longer, especially in outdoor or high-moisture environments.
- Structural Integrity: Rusted nails can weaken and eventually fail. Galvanization helps maintain strength over time.
- Cost-Effective: While slightly more expensive than non-galvanized nails, they save money in the long run by reducing the need for replacements and repairs.
Common Uses for Galvanized Nails
- Outdoor Construction: Decks, fencing, roofing, and siding.
- Treated Lumber: Pressure-treated wood is often corrosive, and galvanized nails resist this corrosion.
- Moist or Humid Environments: Places like bathrooms, kitchens, or coastal areas.
