lb/ft³ to g/cm³: Converting US Density to Chemistry Units
When US engineering data needs to be compared against chemistry reference tables or material science databases (which use g/cm³), you divide by 62.428. Equivalently, multiply by 0.016018. This conversion is frequently needed when importing ASTM material data into international research papers or when comparing mineral samples against published geological references.
- Take the density value in lb/ft³.
- Divide by 62.428 to convert to g/cm³.
- Alternatively, multiply by 0.016018.
- Check: steel at 490 lb/ft³ ÷ 62.428 = 7.85 g/cm³ ✓.

Solved Examples: lb/ft³ to g/cm³
Question 1: A rock sample from a quarry has a measured density of 165 lb/ft³. A geologist needs this in g/cm³ for mineral identification.
Solution:
Density in g/cm³ = lb/ft³ ÷ 62.428
= 165 ÷ 62.428
= 2.64 g/cm³
Answer: 165 lb/ft³ = 2.64 g/cm³ — consistent with quartz-rich sandstone or feldspar.
Question 2: Expanded clay aggregate (Hydroton) has a bulk density of 25 lb/ft³. Express in g/cm³.
Solution:
Density in g/cm³ = lb/ft³ ÷ 62.428
= 25 ÷ 62.428
= 0.40 g/cm³
Answer: 25 lb/ft³ = 0.40 g/cm³ — lightweight aggregate that floats in water.
Question 3: A tungsten carbide drill bit material is rated at 975 lb/ft³. Convert to g/cm³.
Solution:
Density in g/cm³ = lb/ft³ ÷ 62.428
= 975 ÷ 62.428
= 15.62 g/cm³
Answer: 975 lb/ft³ = 15.62 g/cm³ for tungsten carbide (WC-Co composite).

Mineral Identification in Field Geology
Field geologists in the US measure hand-specimen density using displacement methods that yield results in lb/ft³. Converting to g/cm³ allows comparison against mineral identification databases (e.g., Mindat.org, Dana’s System). Key diagnostic ranges: carbonates 2.7–2.9, sulfides 4.0–7.5, oxides 4.0‐5.3, native metals 8.0–22.0 g/cm³. A precise conversion helps distinguish look-alike minerals.
Float-Sink Separation in Recycling
Recycling facilities use float-sink tanks with heavy liquids (bromoform at 2.89 g/cm³, methylene iodide at 3.32 g/cm³) to separate materials by density. Incoming materials may be characterized in lb/ft³, and conversion to g/cm³ determines which heavy liquid to use. Plastics (0.9–1.4 g/cm³) separate from metals (2.7–19 g/cm³) effectively with the right liquid density selection.
Key Takeaways
- 1 lb/ft³ = 0.016018 g/cm³ (divide by 62.428).
- Result equals specific gravity directly.
- Used to match US field data with international mineral databases.
- Quick method: divide lb/ft³ by 62.4.
- Essential for recycling, geological surveys, and materials research.
