Useful volume conversion factors
| Conversion | Factor | Typical use |
|---|---|---|
| m3 to liters | L = m3 x 1000 | Tanks and fluid volumes |
| liters to m3 | m3 = L / 1000 | SI calculations |
| US gallons to liters | L = gal x 3.785411784 | Fluid handling |
| ft3 to m3 | m3 = ft3 x 0.0283168466 | HVAC and pipe volume |
| in3 to mL | mL = in3 x 16.387064 | Small parts and engines |

How it works
Volume conversion method
2. Convert to target units
target value = base value / target unit factor
The selected result and table values are calculated from the same base value.
3. Check precision
rounding depends on scale
Very small and very large values use compact scientific notation to stay readable.
