Conversion method
Specific volume is volume per unit mass. It is the reciprocal of mass density for the same material and conditions.
L/kg = x × 1000
10 m³/kg = 10000 L/kg.
| m³/kg | L/kg |
|---|---|
| 1 | 1000 |
| 5 | 5000 |
| 10 | 10000 |
| 25 | 25000 |
| 50 | 50000 |
| 100 | 100000 |

Precision of specific volume conversions
All 9 specific volume units convert through Cubic meter per kilogram (m³/kg). 9 have an exact defined relationship to the base unit and 0 are conventional or measured values. Results and the tables on this page come from the same engine, so a table value can be checked against the converter directly.
Standard display shows up to six decimal places, switching to scientific notation for very large or small values. Calculation uses JavaScript binary floating point independently of display rounding, so extra digits are not a claim about measurement accuracy. Each unit lists its own source; a citation records where the definition comes from, not an independent review. See Conversion methodology for the review and correction process.
