How to Use This Calculator
  1. Enter total personnel count and days of supply.
  2. Set meals per day (typically 3) and select ration type: 0=MRE, 1=UGR-A (fresh cook), 2=UGR Heat and Serve.
  3. Review Total meals and Weight (lb) for requisition quantities.
  4. Use Cases/modules and Pallets to plan storage and 463L pallet loading.
  5. Check Prep water (gal) for UGR rations to ensure water assets support feeding operations.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Personnel = 200, Days of supply = 7, Meals per day = 3, Type (0=MRE, 1=UGR-A, 2=UGR-HS) = 0 = 4 input(s) provided
  2. Calculate Total meals
    Total meals = personnelCount * mealsPerDay * daysOfSupply
    4200 = 4200
  3. Calculate Weight
    Weight = round(totalMeals * weightPerMeal)
    6300 = 6300
  4. Calculate Cases/modules
    Cases/modules = ceil(totalMeals / unitsPerCase)
    350 = 350
