Here's an interesting article that says what used to be the three-legged stool of retirement (Social Security, pensions and personal savings) is now a four-legged stool of retirement (Social Security, employer retirement plans, home equity and work.) We'll start with their thoughts on Social Security:
One liter of water weighs 1 kg., and 1 gallon of water is equal to 3.7854118 liters; therefor, 1 gallon weighs 3.7854118 kg, which is 8.345404487293294 pounds. Fresh water is take 39.2 degrees Fahrenheit . 1 gallon of fresh water is about 8.36 pounds (Gallon of water weigh calculator). For US: 128 ounces to a gallon, about 30 g/ounce (memory says 29.6g/oz but I would not trust my life on it.) 128*29.6g = 3788.8g = 3.788.8 Kg *2.2lb/kg about = 8.33lb.

A quart of water weighs about 2 pounds. The exact weight of the water can vary based on its temperature, but 2 pounds per quart is a reasonable estimate for most common situations. Another way to think about the weight of a quart is in relation to the weight of a gallon of water. A gallon of water weighs about 8 pounds at warmer temperatures. There are 4 quarts in each gallon. Therefore, each quart weighs about 2 pounds for a total of 8 pounds. It's important to note that a gallon actually weighs slightly over 8 pounds in many common situations, 8.3 on average, so a quart generally weighs just over 2 pounds.
