Ready to leave. Able to carry what you need.

Compose your bag, compare the weights and distinguish what you actually carry from what's left in the vehicle.

An inventory, not an imposed list

Every item counts. So does its weight.

Select the items that are useful to your situation. The library contains 76 optional items; no items are checked by default. The proposed weights are examples, without reference to a commercial model: replace them with your measurements, packaging and batteries included. A zero weight means "to weigh": inform it before including the item.

A total weight is not a validation of the bag. It does not prove your ability to wear it or an autonomy of 72 hours. No universal threshold as a percentage of body weight is applied. The 1.5 kg empty bag and the 2 L water are an initial scenario to adapt, not a prescription.

How to use your result.

The method, useful actions and limitations of the calculation, with the same structure as other PrépaCivile tools.

Calculation method

For each item included: mass = quantity × unit weight in grams ÷ 1,000. The total bag adds up these masses, the empty bag and water it contains. For planning, 1 L of water is counted as about 1 kg; the empty container is counted separately.

Items worn or carried on your body and items in the vehicle have separate totals. Your total carried load includes the bag plus items marked “on your body”. Unchecked items are excluded. One pound is exactly 0.45359237 kg.

Example: empty bag 1.5 kg + water 2 L + two lamps 100 g = 3.7 kg in the bag. A 500 g coat declared "on your body" carries the load on the person to 4.2 kg; it does not change the total of the bag.

Practical next steps

Plan an easy-to-take kit and customize it according to the destination, season and people to accompany.
Keep drugs, documents and media accessible. Add the needs of children and animals.
Weigh the real objects, then the complete bag. Pouchs, packaging and accessories can explain a discrepancy.
Try the bag in safe conditions adapted to your situation. Share the equipment and plan a solution if necessary.
In case of evacuation order, follow the instructions of the authorities. Do not delay your departure to complete the inventory.

Limitations of the result

A result below your personal goal does not mean that the bag is safe or comfortable. The tool does not know your health, mobility, distance, or terrain. The target entered is a planning comparison, not a medical limit.

This selection is not an exhaustive list nor a certified kit. No sample weight is a verified product measure. Neither the sufficiency of water or food, nor the duration of autonomy, nor the volume of the bag are evaluated.

Frequently Asked Questions

Why not apply 10% or 20% of body weight automatically?

A percentage is not enough to determine what a person can carry in an evacuation. You can enter a suitable personal target, but the calculator never certifies the carrying capacity.

Are water and the empty bag already counted?

Yes, in the dedicated fields. Water bottles and hydration bladders in the inventory refer to their empty containers. If you enter an object filled with its total weight, remove the corresponding water from the dedicated field to avoid double counting.

How to prepare the bags of several people?

This scenario describes a single bag and its carrying person. Export the first inventory, then prepare the next one. A shared object must be assigned to a real location, without duplicate between the bags.

Is my information stored?

No. The calculations remain in the browser, without account or transmission of entries. Reloading erases the scenario. The CSV contains selected items and their masses in metric units, even if the screen displays pounds.
