   Ethyl rubbing alcohol has an extremely bitter taste from additives. The specific gravity of Formula 23-H is between 0.8691 and 0.8771 at 15.56 °C (60.01 °F). Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water.

It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...

5. Alcohol fuel - Wikipedia

   en.wikipedia.org/wiki/Alcohol_fuel

   In other words, for the same energy content as one liter or one gallon of gasoline, one needs 1.6 liters/gallons of ethanol and 2.1 liters/gallons of methanol. The raw energy-per-volume numbers produce misleading fuel consumption numbers, however, because alcohol-fueled engines can be made substantially more energy-efficient.

6. Alcohol proof - Wikipedia

   en.wikipedia.org/wiki/Alcohol_proof

   Thus pure 100% alcohol will have 100×(7 ⁄ 4) = 175 proof, and a spirit containing 40% ABV will have 40×(7 ⁄ 4) = 70 proof. The proof system in the United States was established around 1848 and was based on percent alcohol rather than specific gravity. Fifty percent alcohol by volume was defined as 100 proof. [4]
