You probably read somewhere that you should drink between 12 and 15 cups of water per day. That’s pretty close to one whole gallon! But have you ever wondered how heavy that much water is? To be more precise, how heavy is a gallon of water?

8 ounces isn’t a lot of weight. It’s the same as half a pound or 227 grams, which is almost as light as a feather. Not literally, of course, since a feather will only weigh around 0.0082 grams.

10 kilograms is the same as 10,000 grams. In imperial units, it equals 22.0462 pounds or 352.74 ounces.

A ton is equal to 2,000 pounds 907.185 kilograms. A ton differs from a metric ton, which is equal to 1,000 kilograms or 2,204.62 pounds.

A fully loaded concrete truck can hold between 0.3 and 0.4 cubic yards of concrete at once.

The weight of a yard of dirt depends on how much moisture is in it and whether or not it is compacted. Dry dirt typically has a weight range of 1 to 1.3 tons per yard, whereas wet, compacted dirt can weigh as much as 1.7 tons per yard.

If 16 ounces equals one pound, then 10 ounces is the same as 5/6 of a pound. This is also equal to 283.495 grams or 0.283495 kilograms.

A single quarter weighs 0.2 ounces (5.670 grams). A standard coin roll for quarters can hold up to 40 quarters at most. So, a roll of quarters, minus the weight of the roll, will weigh 8 ounces (226.769 grams).

While knowing that 1 gram is the same as 0.035274 ounces, that won’t help you get very far for getting a feel of what 1 gram is. However, there’s a simple solution to this problem: memorizing objects that weigh about 1 gram.

5 grams is the same as 0.17637 ounces or about 0.0110231 pounds. While knowing the conversion figures of 5 grams can be helpful, they won’t inform you of how much it feels in the palm of your hand.

Grams are used for measuring small objects, whereas kilograms are used for measuring large or heavy objects. A gram is equal to 0.001 kilograms, and a kilogram is the same as 1,000 grams.

20 pounds, the equivalent of 9.07 kilograms, is pretty heavy to lift using a single hand. Unless you’re built like the Rock, that is.
