The short answer: Grams
In fact, a water-bottle's capacity is generally measured in Liters, since liters are the metric standard for measuring volume (e.g. capacity).
However, the metric Liter was created by finding the volume of one kilogram of water. In other words, a single gram of water is (at room temperature) almost exactly one milliliter. To summarize, 1g of water = 1mL
Since a milligram is 1/1000 of a gram, measuring water in milligrams would result in a bottle containing thousands of milliliters.
Milligrams would make more sense.

Food ingredients such as salt, sugar, etc.
1 milligram is equal to 0.001 grams. So, your weight in milligrams would depend on your weight in grams. For example, if you weigh 70 kilograms, that would be equal to 70,000,000 milligrams.
Any unit of measure for mass such as 'ounces', 'milligrams', 'kilos' etc.
One can purchase a Nalgene waterbottle online at a number of different sites, and they can be shipped anywhere in the continental United States. The best place to buy a Nalgene waterbottle would be the Nalgene website.
The mass of an ant would typically be measured in milligrams (mg) or micrograms (μg).
Ruler
Milligrams (mg) would most likely be used to measure the medicine in a pill.
Mass. Any mass can be measured in mg. But as there are 1000 mg in one gram (the mass of a small coin) unless you want a very large number of milligrams, it will have to be to measure a small or very low density object.
mg is an abbreviation for milligrams, so your answer would be 3675 milligrams.
