Liter per Gram (L/g)
Definition: Equal to one liter of volume per gram of mass — a comparatively large specific volume unit, since one liter per gram equals 1,000 liters per kilogram.
History: Rarely a primary reporting unit in its own right; it exists in conversion tables as the natural combination of the liter and the gram for describing extremely voluminous, low-density substances such as gases or aerogels.
Current use: Occasionally used in gas physics and chemistry to describe very large specific volumes, such as gases at low pressure or highly porous low-density materials like aerogel, where cubic meter per kilogram would produce inconveniently small numbers.
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.

- The number you want to convert, expressed in the "From" unit. Accepts decimals.
- From Unit
- The specific volume unit your input value is currently measured in.
- To Unit
- The specific volume unit you want the result converted into. Use the swap button to flip From and To instantly.
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 Liter per Gram → Cubic Foot per Pound: multiply by 16.036005. For example, 1 L/g × 16.036005 = 16.036005 ft³/lb.
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 L/g equals 16.036005 ft³/lb. For scale, liquid water has a specific volume of about 0.001 m³/kg (roughly 0.001 L/g) — 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 0.83 L/g), nearly a thousand times more space per kilogram.
Frequently Asked Questions
How many Cubic Feet per Pound are in 1 Liter per Gram?
1 Liter per Gram (L/g) equals exactly 16.036005 Cubic Feet per Pound (ft³/lb).
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.
