How do you calculate the alcohol percentage in home brew beer when you do not have an initial specific gravity reading?

Ok, so you forgot to take an original gravity reading (O.G.).
Hopefully you brewed with a kit or a recipe that tells you the anticipated O.G. Get that number and then when your homebrew finishes get the final gravity reading (F.G.).
Calculate the alcohol percentage with this calculation:
% ABV = ((anticipated O.G.) - (F.G.)) / (specific gravity of ethanol)
% ABV = ((anticipated O.G.) - (F.G.)) / 0.789

How will you calculate normality using specific gravity?
by bottle method
How do you calculate specific gravity of a petroleum product?
How to calculate the specific gravity of a petroleum product involves using the ratio of the specific product density to that of water. This type of calculation is always determined at 60-degrees Fahrenheit.
What is specific gravity and percentage purity of Hydrochloric acid?

How do you calculate specific gravity of sodium silicate at different temperature?
By BOB meter.
Does a etg test just test for alcohol?
It tests for Ethylglucuronide (ETG)--Alcohol, Creantanine levels, Specific Gravity, Nitirite, and ph.
What floats in ethyl alcohol?
Ethyl alcohol has a specific gravity of 0.78, so it will float on water (1). Olive oil is 0.703 so it will float on ethyl alcohol.
Hi I Know the specific gravity of a gas at NPT How can you calculate the specific gravity of tha gas at 400 bar pressure and ambient temperature?
Is this a school question that you simply don't know the answer to?
How do you calculate volume with specific gravity and mass?
An abstract, esoteric mathematical operation known as "division." Divide mass by density, and you get volume. A note for purists: Technically speaking, specific gravity is not density, it is a ratio of densities. However, since one of the materials in the ratio is water, and its density is well known, it's easy to calculate the density of a material from its specific gravity.
How is the ABV on a bottle of wine calculated?
Using a hydrometer, the specific gravity (SG) of the wine is measured before and after fermentation. The numbers are then used in the following formula to calculate Alcohol By Volume. ABV = (initial SG - final SG) / 7.36
How do you calculate the alcoholic content of beer?
Alcohol content in beer is measured in %/volume. Multiply the number of units of beer by the % alcohol to get the total volume of alcohol. 12 oz. of 5% beer = 12 x .05 = 0.6 ounces of pure alcohol. If you do not know the %-age of alcohol, as in home brewing, you would need to test the specific gravity. Testing equipment is available in home brewing catalogs.
