About Converting Pounds per Cubic yard to Grams per Cubic foot
Pound per Cubic yard and Gram per Cubic foot both measure density — mass per unit volume — a property used to identify materials, check manufacturing quality, and predict whether something floats or sinks. As a fixed reference point, water has a density of exactly 1000 kg/m³ (1 g/cm³, 1 g/mL) at its temperature of maximum density, which is why many density figures in science and engineering are quoted relative to water. Both are mass per volume density units.
Formula
grams per cubic foot = pounds per cubic yard × 16.7997174074
This factor comes from each unit's defined relationship to the category's base unit: 1 pound per cubic yard equals 0.593276421258 base units, and 1 gram per cubic foot equals 0.0353146667215 base units, so dividing one by the other gives the direct pound per cubic yard-to-gram per cubic foot factor of 16.7997174074.
Simple example
1 lb/yd3 × 16.79971741 = 16.79971741 g/ft3
1 pound per cubic yard = 16.79971741 grams per cubic foot.
Real-world example
1,000 lb/yd3 × 16.79971741 = 16,799.71741 g/ft3
1,000 pounds per cubic yard = 16,799.71741 grams per cubic foot.

Mass per volume density.
Understanding the Gram per Cubic foot
Gram per Cubic foot (g/ft3) measures density. A gram is a small mass unit and a cubic foot a comparatively large volume, so this combination naturally suits low-density materials rather than typical solids or liquids. It is classified as a mixed metric/US customary density unit.
Uses of the Gram per Cubic foot today
- Can be used to express the density of low-density materials such as insulation foam, packaging material, or gas concentration by volume — for typical solid or liquid materials, kilograms per cubic meter or pounds per cubic foot are more commonly encountered
Gram per Cubic foot — sources
- BIPM SI Brochure — Gram and cubic foot as units combinable to express density, though not a standard industry pairing for general materials.

Frequently asked questions
How many grams per cubic foot are in 1 pound per cubic yard?
1 pound per cubic yard equals 16.79971741 grams per cubic foot, using the exact defined conversion factor rather than an estimate.
How do I convert pound per cubic yard to gram per cubic foot?
Multiply the pound per cubic yard value by 16.79971741. The converter above does this instantly to whatever precision you set.
How do I convert gram per cubic foot back to pound per cubic yard?
Use the reverse factor: 1 gram per cubic foot equals 0.0595248108 pounds per cubic yard. You can also use the swap control in the converter above to flip the direction instantly.
What is a pound per cubic yard?
Pound per Cubic yard (lb/yd3) is a unit of density.
What is a gram per cubic foot?
Gram per Cubic foot (g/ft3) measures density. A gram is a small mass unit and a cubic foot a comparatively large volume, so this combination naturally suits low-density materials rather than typical solids or liquids. It is classified as a mixed metric/US customary density unit.
Is the pound per cubic yard to gram per cubic foot conversion exact?
Yes. Both pound per cubic yard and gram per cubic foot are defined by fixed standards rather than physical artifacts, so the factor of 16.79971741 used above is exact to as many digits as you choose to display.
What's the difference between density and mass concentration?
Density is the mass of a pure substance or material per unit volume. Mass concentration is the mass of one component — like a dissolved solute — within a mixture's total volume. The two use the same kind of units but describe different physical situations.
