Converting g/cm³ to lb/ft³: From Lab Data to US Specifications
Chemical and material science data is often published in g/cm³, but US manufacturing specifications, ASTM testing standards, and construction documents require lb/ft³. The conversion factor is 1 g/cm³ = 62.428 lb/ft³. This factor combines the mass conversion (grams to pounds) with the volume conversion (cm³ to ft³).
- Start with the density value in g/cm³.
- Multiply by 62.428 to convert to lb/ft³.
- Verify: water (1.000 g/cm³) × 62.428 = 62.428 lb/ft³ (correct).
- For inverse conversion, divide lb/ft³ by 62.428.
Metals and Alloys: g/cm³ to lb/ft³
Key metal densities used in machining, casting, and metallurgy specifications:

Worked Problems: g/cm³ to lb/ft³
Question 1: Brass has a density of 8.53 g/cm³. A US foundry needs this in lb/ft³ for their sand casting specification.
Solution:
Density in lb/ft³ = g/cm³ × 62.428
= 8.53 × 62.428
= 532.7 lb/ft³
Answer: 8.53 g/cm³ = 532.7 lb/ft³ for brass alloy (C360).
Question 2: A magnesium alloy (AZ31) has a density of 1.77 g/cm³. Convert for an aerospace parts list.
Solution:
Density in lb/ft³ = g/cm³ × 62.428
= 1.77 × 62.428
= 110.5 lb/ft³
Answer: 1.77 g/cm³ = 110.5 lb/ft³ — magnesium is about one-third lighter than aluminum, making it attractive for weight-critical aerospace parts.
Question 3: A nickel superalloy (Inconel 718) measures 8.19 g/cm³. Express in lb/ft³.
Solution:
Density in lb/ft³ = g/cm³ × 62.428
= 8.19 × 62.428
= 511.3 lb/ft³
Answer: 8.19 g/cm³ = 511.3 lb/ft³ for Inconel 718 used in jet engine turbine blades.

Using Density for Weight Estimation in Machining
Machinists calculate part weight by multiplying density (lb/ft³) by part volume. For a steel shaft 6 inches in diameter and 24 inches long: volume = π × 3² × 24 = 678.6 in³ = 0.393 ft³. Weight = 0.393 × 490 = 192.6 lb. This quick estimation determines whether manual handling or a crane is needed, and calculates shipping costs before CNC programming begins.
ASTM Material Testing Standards
ASTM International publishes density in both g/cm³ and lb/ft³ in their material standards. For example, ASTM A36 steel is specified at 7.85 g/cm³ (490 lb/ft³). Knowing both forms helps engineers cross-reference international datasheets with American specifications without conversion errors that could lead to over- or under-designed structural members.
Key Takeaways
- 1 g/cm³ = 62.428 lb/ft³.
- Water density (62.4 lb/ft³) is the anchor point for all conversions.
- Density in lb/ft³ ≈ specific gravity × 62.4.
- Critical for US manufacturing specs and ASTM standards.
- Useful for estimating part weight before machining.
