Specific Volume examples

m³/kg to L/kg

10 m³/kg = 10,000 L/kg.

m³/kg to cm³/g

10 m³/kg = 10,000 cm³/g.

m³/kg to ft³/lb

10 m³/kg = 160.1846 ft³/lb.

How to calculate Specific Volume step by step

  1. Choose the starting unit and the target unit.
  2. Enter your value.
  3. Read the converted value, plus the conversion factor in both directions.

How to read your Specific Volume result

Specific volume is volume per unit mass, the reciprocal of density. Its SI unit is the cubic metre per kilogram. Because 1 cm³/g and 1 L/kg both equal 0.001 m³/kg, those two units are numerically identical.

Common mistakes when calculating Specific Volume

  • Confusing specific volume with density: one is the reciprocal of the other.
  • Forgetting that 1 L/kg and 1 cm³/g are the same size.
  • Applying a liquid value to a gas: specific volume of gases changes strongly with temperature and pressure.

Specific Volume FAQ

How is specific volume related to density?

Specific volume is 1 divided by density, so a density of 1,000 kg/m³ is a specific volume of 0.001 m³/kg.

How many m³/kg is 1 ft³/lb?

1 ft³/lb is about 0.062428 m³/kg.

Are cm³/g and L/kg the same?

Yes. Both equal 0.001 m³/kg.

What is the base unit for specific volume?

This converter uses cubic meter per kilogram (m³/kg) as the common base unit: every value is first converted to it and then to the target unit.

How do I convert between two specific volume units?

Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.

How many liters per kilogram are in 1 cubic meter per kilogram?

1 m³/kg = 1,000 L/kg.

How many cubic centimeters per gram are in 1 cubic meter per kilogram?

1 m³/kg = 1,000 cm³/g.

How many cubic feet per pound are in 1 cubic meter per kilogram?

1 m³/kg = 16.01846 ft³/lb.

Which specific volume units does this converter support?

It covers 6 units: cubic meter per kilogram (m³/kg), liter per kilogram (L/kg), cubic centimeter per gram (cm³/g), cubic foot per pound (ft³/lb), cubic foot per kilogram (ft³/kg), US gallon per pound (gal/lb).

How accurate is the specific volume converter?

Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
