What is 1 lb/ft3 in g/cm3?

1 pound per cubic foot equals approximately 0.016018 grams per cubic centimeter (0.0160184634 g/cm3 exactly, using the international definitions of the pound and foot).

How do I convert lb/ft3 to g/cm3?

Multiply the value in lb/ft3 by 0.0160184634. For example, 62.4 lb/ft3 (close to the density of water) becomes 62.4 × 0.0160184634 ≈ 0.9996 g/cm3.

What is the density of water in lb/ft3 and g/cm3?

Water at 4 °C has a density of 1.000 g/cm3, which equals approximately 62.428 lb/ft3. This is a useful anchor point for checking conversions.

Why are both units still in use?

The US construction and building-materials industries historically use imperial units (lb/ft3), while science, chemistry, and international engineering use metric (g/cm3). Converting between them is routine in cross-disciplinary work.

Is g/cm3 the same as g/mL or kg/L?

Yes. Since 1 mL = 1 cm3 and 1 L = 1000 cm3, the numerical values are identical: 1 g/cm3 = 1 g/mL = 1 kg/L.

Summary

Density can be expressed in many unit systems. The pound per cubic foot (lb/ft3) is common in US engineering and construction, while grams per cubic centimeter (g/cm3) is the standard in science and most of the world. This converter applies the exact factor: 1 lb/ft3 = 0.0160184634 g/cm3, derived from the international pound (0.45359237 kg) and the foot (0.3048 m). Use it to cross-reference material datasheets, building codes, and laboratory measurements.
