For anyone not familiar with gallons and lbs the conversion(for these purposes) is 1 gallon=5 litres and 1lb=500grams and I kilo=2.2lbs.

Tinned meals: 30 tins per person(pasta, chunky type soups, irish stew, stewing steak, etc.etc.) Tinned/bottled meat and fish spreads: 12 tins or bottles(for sandwiches). Peanut Butter: at least 1 bottle per person. Jams and Marmalades: at least 1 bottle per person. Crackers: minimum 4 packs per person(for sandwiches and snacks). Breakfast cereal: at least one pack per day of your favourite cereal or buy a "variety pack" you'll need 1 individual serving per person per day of those. Fruit juices: 1 gallon per person. Coffee, tea, hot chocolate: minimum 1 pack per person. Dried milk(tins):minimum 1 tin per person, increase if frequent milk drinker, 2 tins per child.

Vinegar, plain: 1 gallon for disinfectant purposes. Toilet paper: minimum 1 pack of 10(most preppers have hundreds, its the favourite prep!) Kitchen Towels:6 rolls. Paper plates, cups, disposable cutlery: to cut down on water use for washing up. Manual tin opener, butterfly type is cheap, get several. Camp Stove, for cooking and boiling water, plus fuel for same,(remember if your using this indoors you need some ventilation). Torches: 1 per person minimum and at least 2 sets of batteries for same, personally I prefer the "wind up" sort...no batteries needed. Radio: battery powered and spare batteries for same. Fire Extinguishers: minimum 1, also a "fire blanket" for kitchen fires. Battery operated smoke detectors for obvious reasons. if your emergency is in the winter you will also need some form of alternative heating to the power grid, I suggest a portable gas heater and 2 gas cylinders(1 fitted, I spare), if you use this just on one bar 1 cylinder will last you I month......just!! this is just a very basic list, you can add to it as you wish, and remember "rotate, rotate, rotate".
