Volume

To find the volume in cubic yards, first convert the dimensions to yards: 40 feet = 13.33 yards, 80 feet = 26.67 yards, and 5 inches = 0.14 yards. Next, multiply the length, width, and height in yards to get the volume in cubic yards. Therefore, the volume of the 40'x80'x5'' slab is approximately 59.11 cubic yards.

There are approximately 3.78 8 oz bottles in a liter.

It is approximately 620ml. Just for your information, 1 US fluid ounce = 29.5735296 ml.

1000 millilitres = 1 litre so 1200 millilitres = 1200/1000 = 1.2 litres. Simple!

There are approximately 224.71 gallons in 30 cubic feet.

1000 kg/ 2 m3 = 500 kg per cubic meter density or 0.5 g/cm3 or approximately half the density of water

1.12 liters is equal to 1120 milliliters (mL) because there are 1000 milliliters in one liter.

I'm not sure, but it should be 5 1/4 gallons, or 5.25 gallons

There are approximately 10.5 feet of 20 gauge silver wire in 1 ounce.

Liters (Litres UK spelling) is a unit of volume already. If another unit of volume is provided it can be converted to litres. 1 m3 is equal to 1000 litres.

The conversion of liters to kilograms depends on the substance being measured, as different substances have different densities. You would need to know the density of the specific substance in order to accurately convert liters to kilograms.

5 fl oz. A tablespoon is equivalent to 0.5 liquid ounces so there are 2 tablespoons in 1 ounce. There are two different ounces, ounces of weight/mass and ounces of volume (fluid). This can change when you are using the tablespoon 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 tablespoon measures volume not weight. In order to convert tablespoons or teaspoons to ounces or back, You need to know what is being measured. A spoon of lettuce will weigh different than a spoon of gold in solid ounces.

21 liters = 5.5476 US gallons = 4.6194 imperial gallons

1 quart = 2 pints

1 pint = 0.5 quart

In general, oil will float on the water surface. That is, it will spread out in a layer on the top of the water. This is because oil is less dense than water, and is immiscible with it (meaning it doesn't mix with the water).

So if you think about it, the question is ambiguous. The answer does not depend on the volume of water (e.g. "gallons") but rather on the surface area (e.g. square feet, sq miles, etc).

For example you could have a very deep lake that contains many hundreds of thousands of gallons of water, but if the perimeter of the lake is very small, the oil may cover the entire lake. Conversely, a puddle in a parking lot may be only an inch deep, but if the puddle extends across the entire parking lot, it may contain relatively few gallons of water, but the oil may only cover a small fraction of it if the size of the puddle is very very large.

So the quest really is, how THICK will a layer of oil be if it spreads out on the water surface. Knowing this, you can calculate the amount of surface AREA that a quart of oil will spread out over.

I like to do my calculations in metric, but I'll convert back into English units for the result.

Assume that the oil makes a 1 mm film over the surface. (About 1/25th inch)

Some conversions:

1 mm = 0.1 cm

1 quart = 946 mL = 946 cm3

The area the oil would take up is the volume divided by the thickness:

A = 946 cm3/0.1 cm = 9460 cm2

So that's your estimated answer, but now let's convert it into something more meaningful.

1 m = 100 cm, so 1 m2 = 10,000 cm2

So 9460 cm2 = 0.946 m2

Rounding up slightly, we can say that this is close to 1 square meter, which is close to 1 square yard (i.e. 9 square feet).

So if the oil is 1/25th of an inch thick, the quart of oil will cover about one square yard of water (regardless of how DEEP the water is).

But remember, this was just a guess at the thickness of the oil. Additionally it assumes that the oil sticks together in a film and does not disperse.

If the oil is 10 times thinner (i.e. 0.1 mm) then the area covered will be ten times as great (i.e. 10 sq yards or 90 square feet)!

6.75 liters is equal to 6,750 cubic centimeters (cc).

The milliliter and the cubic centimeter are equal volumes.

That depends on the liquid. To get the MASS, multiply the volume by the density. To get the WEIGHT, multiply the mass by the gravity.

Petrol is typically measured in liters (L) in fuel stations. If you need to measure a small quantity of petrol, you can use a measuring cup or a container with milliliter (ml) markings to measure the exact volume needed.

32 fluid ounces equates to approximately 976 mL

One Imperial gallon = about 0.004546 cubic meters.

The gallon measuring system is primarily used in the United States and was based on the British system of measurement. The origins of the gallon can be traced back to medieval England, but it was not discovered by a single individual.

A pound is a measure of mass. A gallon is a measure of volume. The two measure different things and it is not sensible to even consider converting from one to the other.

If you are not convinced, consider a gallon of water. How many pounds? Next consider a gallon of treacle. How many pounds?

1000 mL = 1 L so 45.6 mL = 0.0456 L. Simple, really!
