How to use this calculator
- Enter the known values in the units shown. Results update as you type.
- Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
- Use the worked example to check the method. Reset restores the starting fields.

Formula and method
100 kg over 10 m² gives 10 kg/m² and cube loading about 3.16228 kg/m³.
Mass loading = m/S; cube loading = m/S^(3/2).
Worked example
Enter these known values and leave the other values blank.
- Wing area (S)
- 10 m²
- Aircraft mass
- 100 kg
- Mass per wing area
- 10 kg/m²
- Wing cube loading (W==CL==)
- 3.162 kg/m³
Assumptions and limitations
- The captured weight controls contain mass units. These results are mass loading, not force loading in N/m².
- Wing area is the planform reference area. Cube loading is a dimensional comparison and does not independently predict performance.
- Aircraft presets are approximate illustrative records rather than operational specifications.
- Enter known quantities and clear the unknown to use available inverse branches. Locks retain supplied values. Consistency messages cover fully visible equations; identities with hidden dependencies may require a manual consistency check. Preset values are illustrative approximations, and unit selectors preserve the underlying quantity.
Common questions
How do I solve for a different quantity?
Clear that quantity and supply enough independent known values. Some outputs are one-way or tied to a selected preset, so they cannot determine every input.
