Gram-force per Cubic Centimeter (gf/cm³): Definition, Unit of Specific Weight and Conversions
Gram-force per cubic centimeter (symbol: gf/cm³) is a metric unit of specific weight that measures the weight of a material contained within one cubic centimeter of volume. Unlike mass density, which measures mass per unit volume, specific weight measures gravitational force per unit volume and therefore depends on the local acceleration due to gravity.
Definition
One gram-force per cubic centimeter represents the specific weight of a material exerting a gravitational force of one gram-force over a volume of one cubic centimeter.
1 gf/cm³ = 9,806.65 N/m³

Real-World Examples
Gram-force per cubic centimeter is occasionally encountered in older engineering references and educational resources. Modern engineering practice generally prefers SI units such as newton per cubic meter (N/m³) or kilonewton per cubic meter (kN/m³) for reporting the specific weight of construction materials, soils, and fluids.
Frequently Asked Questions
