  1. Total Water Needed: This field provides the total amount of water required for the specified period.

"Emergency Water Calculator" Formula:

The "Emergency Water Calculator" formula is simple. The total amount of water required is calculated by multiplying the number of people by the number of days by the gallons per person per day, and adding the gallons required for pets and medication (if any).

Total Water Needed = (Number of People x Number of Days x Gallons per Person per Day) + (Number of Pets x Number of Days x Gallons per Pet per Day) + (Number of People with Medications x Number of Days x Gallons per Medication per Day)

Illustrative Examples:

Let's assume that a family of four, with one pet, requires water for five days. Each person requires 1.5 gallons of water per day, and the pet requires 0.5 gallons of water per day. No one in the family requires medication. To calculate the total amount of water required, we will use the "Emergency Water Calculator."

Number of People: 4 Number of Days: 5 Gallons per Person per Day: 1.5 Number of Pets: 1 Gallons per Pet per Day: 0.5 Number of People with Medications: 0 Gallons per Medication per Day: 0

Total Water Needed: (4 x 5 x 1.5) + (1 x 5 x 0.5) + (0 x 5 x 0) = 35 gallons
