Multiply ABW (alcohol by weight) by 1.25 to get ABV (alcohol by volume).
Multiply ABV by 0.8 to get ABW.
This isn't exact because different beers have different ingredients, but it will get you very close every time.
alcohol % per volume x 2 = proof. So 80 Proof booze is 40% alcohol. Divide the proof spirits by 2 to get the alcohol by volume. Alcohol by volume multiplied by .8 gives alcohol by weight. This is often the reason Canadian beer are thought to be stronger an 8% proof beer is the same as a 3.2 beer buy weight.
To convert volume to weight, you need to know the density of the substance in question. The formula is Weight = Volume x Density. First, find the density of the material, then multiply it by the volume to get the weight.
You cannot. The problem here is you have weight per area and you want to convert to weight per volume. You need a third dimension to the area to calculate this.
Specific weight is a measure of the weight per unit volume of a substance. For liquids, specific weight is typically expressed in units like pounds per cubic foot or newtons per cubic meter. It is calculated by dividing the weight of the liquid by its volume.
To convert 3 mmol of alcohol to blood alcohol concentration, you would need to know the volume of distribution in the body. Without this information, a direct conversion is not possible. Blood alcohol concentration is typically measured in units of mass per volume (e.g., g/dL or mg/L), not in mmol.
Pounds per cubic foot of volume and used to weight the two do not compare.
The only advantage is that alcohol is "renewable". Alcohol has less energy per unit volume and/or weight, and currently is more expensive.
To convert cubic meters to weight, you need to know the density of the substance you are measuring. Multiply the volume in cubic meters by the density in kilograms per cubic meter to get the weight in kilograms. Alternatively, you can use specific gravity if the substance is a liquid.
Density is mass per unit volume, and sometimes in some industries weight per unit volume is used. Weight per unit volume is also sometimes called specific weight. Weight and mass are not the same. Volume per unit mass is called specific volume, and is the reciprocal of density. It is not clear whether volume per unit weight can also be used as a measure of specific volume.
To convert cubic meters to tonnes, you need to know the density of the material you are measuring. Multiply the volume in cubic meters by the density in tonnes per cubic meter to get the weight in tonnes. The formula is: weight (tonnes) = volume (cubic meters) * density (tonnes per cubic meter).
To actually perform this operation, the weight of a given volume of syrup needs to be determined first. Once the weight per volume is known, then any volume of syrup can be converted into any weight, and any weight can be converted into any volume. A form of this same operation is performed daily by pilots who need to convert gallons/liters of fuel into pounds/kilos for the purpose of determining a safe weight and balance for their aircraft.
You cannot directly associate weight or volume with length. In order to convert to volume you need to know the shape and most likely another 2 dimensions. This will get you the volume. You then need to know the density, usually in grams per millilitre. and apply this. Then convert the units.
