This document is a work in progress.
This is a worksheet for calculating the amounts of emergency supplies for a family of a given size.
Change these variables to recalculate the numbers (I’m using the mind-bogglingly amazing Calca to edit this document):
persons = 6 # 3 adults, 2 kid, 2 pets averages to ~6 persons days = 10 # minimum recommended by US government
If treated properly, water can reliably be stored for 5 (recommended) and in some cases even up to 10 years.
water per person per day = 1gl # a recommended minimum for drinking, food prep and hygiene supply of water = persons * days * water per person per day => 60gl barrel volume = 55gl water barrels = supply of water / barrel volume => 1.0909
calories per person per day = 2,600cal # for a moderately active middle aged male supply of calories = persons * days * calories per person per day => 156,000cal clif builders bar = 270cal energy bars = ceil(supply of calories / clif builders bar) # just for scale => 578

Gas to power the generator (calculation are for the Champion Power Equipment 46539 generator).
tank capacity = 3.8gl burn per hour = 3.8gl / 12 # if running at 50% load (~1500 Watt) hours per day = 8 # running part of the day gas per day = burn per hour * hours per day => 2.5333gl supply of gas = days * gas per day => 25.3333gl jerry cans = supply of gas / 5gl => 5.0667
E.g.: propane for cooking.
