Cubic Foot per Pound (ft³/lb)
Definition: The US customary and imperial unit of specific volume, equal to one cubic foot of volume occupied by one pound of mass.
History: Rooted in the imperial system's foot and pound units, cubic foot per pound became the standard specific-volume unit in American engineering steam tables and refrigeration tables published throughout the 19th and 20th centuries, before SI units became the international scientific norm.
Current use: Still the standard unit in US HVAC, refrigeration, and steam engineering practice — American steam tables, psychrometric charts, and refrigerant property tables report specific volume in cubic feet per pound.
Cubic Centimeter per Gram (cm³/g)
Definition: A CGS-scale specific volume unit equal to one cubic centimeter of volume per gram of mass; numerically identical to liter per kilogram.
History: Inherited from the CGS (centimeter-gram-second) system of units that predated SI's adoption in engineering, cubic centimeter per gram remained a convenient laboratory-scale unit because sample masses in chemistry and materials science are typically measured in grams rather than kilograms.
Current use: Common in materials science, polymer chemistry, and food science laboratories, where measuring the specific volume of small samples — polymer pellets, powders, bulk density test material — in gram-scale units avoids awkward small decimals.

How Specific Volume Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the cubic meter per kilogram. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Cubic Foot per Pound → Cubic Centimeter per Gram: multiply by 62.359673. For example, 1 ft³/lb × 62.359673 = 62.359673 cm³/g.
Specific Volume vs. Density: Reciprocal Quantities
Specific volume (v) and density (ρ) describe the same physical relationship — mass and the space it occupies — from opposite directions, and they are exact reciprocals of one another: v = 1/ρ. A substance with a high density, like steel at roughly 7,850 kg/m³, has a correspondingly tiny specific volume (about 0.000127 m³/kg), while a low-density substance like air at sea level has a much larger specific volume. Neither quantity is "more correct" than the other; engineers pick whichever one keeps a given calculation's numbers, formulas, and units cleanest, which is why both units families exist side by side across thermodynamics and fluid mechanics.
Where Specific Volume Matters: Thermodynamics and HVAC
Specific volume is the natural variable in steam tables and psychrometric (moist-air) charts, because thermodynamic cycles — compression, expansion, phase change — are usually analyzed per unit mass of working fluid rather than per unit volume. HVAC engineers use the specific volume of moist air to size ductwork and fans, refrigeration engineers use the specific volume of refrigerants to size compressors and evaporators, and power plant engineers use steam's specific volume (which swings enormously between liquid water and superheated steam) to size turbines and piping.
Example
1 ft³/lb equals 62.359673 cm³/g. For scale, liquid water has a specific volume of about 0.001 m³/kg (roughly 0.016036005 ft³/lb) — it's very dense, so a kilogram of it takes up very little room — while dry air at sea level and room temperature has a specific volume of roughly 0.83 m³/kg (about 13.309884 ft³/lb), nearly a thousand times more space per kilogram.
Frequently Asked Questions
How many Cubic Centimeters per Gram are in 1 Cubic Foot per Pound?
1 Cubic Foot per Pound (ft³/lb) equals exactly 62.359673 Cubic Centimeters per Gram (cm³/g).
What's the difference between specific volume and density?
They are exact reciprocals: specific volume (m³/kg) tells you how much space a unit of mass takes up, while density (kg/m³) tells you how much mass fits into a unit of space. Multiplying a substance's specific volume by its density always gives exactly 1 — knowing either one lets you compute the other directly.
Why do engineers use specific volume instead of density?
In thermodynamic cycle analysis, quantities like work and heat transfer are naturally expressed per unit mass of working fluid, so equations written in terms of specific volume avoid extra division steps. Steam tables, refrigerant property charts, and psychrometric charts have historically been tabulated in specific volume for exactly this reason.
How accurate are these conversions?
Every conversion factor used here is derived from the exact, internationally recognized definitions of the underlying mass and volume units (the international pound, the US gallon, the liter) — results are limited only by floating-point display precision, not by rounded conversion constants.
