Try the starting example
- Items: ID, quantity, grams each, consumable yes/no, worn yes/no, fraction allocated to this person zero to one
- Tent,1,2000,no,no,0.5 Food,2,500,yes,no,1 Jacket,1,400,no,yes,1 Stove,1,300,no,no,1
- Allocated mass by item (g)
- Tent: 1000; Food: 1000; Jacket: 400; Stove: 300
- Pack base mass excluding consumables and worn items (g)
- 1300
- Allocated consumable mass inside pack (g)
- 1000
- Allocated worn mass (g)
- 400
- Total allocated pack mass (g)
- 2300
- Total pack plus worn mass (g)
- 2700
Try another scenario
- Items: ID, quantity, grams each, consumable yes/no, worn yes/no, fraction allocated to this person zero to one
- Tent,1,2000,no,no,1 Food,2,500,yes,no,1 Jacket,1,400,no,yes,1 Stove,1,300,no,no,1
- Allocated mass by item (g)
- Tent: 2000; Food: 1000; Jacket: 400; Stove: 300
- Pack base mass excluding consumables and worn items (g)
- 2300
- Allocated consumable mass inside pack (g)
- 1000
- Allocated worn mass (g)
- 400
- Total allocated pack mass (g)
- 3300
- Total pack plus worn mass (g)
- 3700
Calculation method
Calculation method
Allocated mass by item (g)
Quantity×unit mass×supplied carried share.
Pack base mass excluding consumables and worn items (g)
Sum nonconsumable, nonworn allocated items.
Allocated consumable mass inside pack (g)
Sum consumable, nonworn allocated items.
Allocated worn mass (g)
Sum all worn allocated items; worn items are excluded from pack totals.
Total allocated pack mass (g)
Base+inside-pack consumables.
Total pack plus worn mass (g)
Pack+worn, without counting other people’s allocated shares.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- An explicit item-classification mass ledger, not a recommended pack weight or an assessment of carrying ability. Shared fractions allocate ownership here; they do not describe indivisible physical packing.
