Volume

It depends on what you a measuring, for water it would be 2. Cups is a measure of volume. Pounds is a measure of weight and mass. You can not directly convert the two.

14.17 grams

2.4 US gallons is about 9,085 cc

This are 6,6666 bottles, that means 6 and 2/3 bottles.

yes

1 quart = 4 cups

1 cup = 0.25 quart

1 US gallon of space = 128 fluid ounces of space,

regardless of what's in it. Even if it's empty.

45 pints = 5.62 gallons

240 cubic centimeters = 8.1 (8.11536545) US fluid ounces.

Considering that a big bottle of soda is 2 liters, you can guess that a tiny eye dropper would have milliliters.

millilitres. cups are I'd say around 3-400ml

Yes.

If mass remains the same, then density decreases as volume increases,

and relative density determines "floatability".

That is approximately 1,842.719 grams

There are 1000 milliliters in 1 liter.

One milliliter is 0.001 liter

Cubic inches is volume (3D).

While feet * feet is area (2D).

The dimensionality does not match, so no answer is possible.

No, a pint is 2 cups. 2 pints in a quart, 8 pints in a gallon.

About 3.38 fluid ounces per 100mL

volume = L x Wx H

20 x 14 x 48 =13,440

that is in inches..not gallons so your tank is 13,440 square inches...it will hold 58.18 gallons. See the link for computing volume, you can also determine how many gallons you are putting in it if you only partially fill it.

what dimension of 209 ltr oil drum

There are 3.7854 liters in a gallon of water

One imperial gallon is approximately equal to 1.201 U.S. gallons.

One imperial gallon is exactly 4.54609 litres, whereas one U.S. gallon is exactly 3.7854118 liters.

1,615.79 US gallons.

Five US gallons is about 18.93 liters.

20 tbsp.

1 tbsp = 0.5 oz

1 oz = 2 tbsp

In US measure 32 fluid ounces are equal to one quart. One ounce is 0.03 quart or as thirty-two (32) ounces equals 1 quart, so there is 1/32 of a quart in an ounce. But you need to know that 1 Imperial quart = 40 Imperial fluid ounces. Also this relates only to fluid ounces. There are two different kinds of ounces, ounces of weight/mass and ounces of volume (fluid). This can change when you are using the ounces to measure a non-liquid such as flour or sugar since the weight of dry items is not the same as their volume. An ounce of volume is called a "fluid ounce." A quart measures volume not weight. In order to convert quarts to solid (weight)ounces or back, You need to know what is being measured.

400cc equates to approximately 13.5 fluid ounces.

1 litre = 1000 millilitres so 9.6 litres = 9.6*1000 = 9600 millilitres. Simple!
