Alcohol For Stove

[Jordan Calicott]

How much does 8 fl oz of alcohol weigh? Also, if I’m using the Brasslite Turbo F Stove for a weekend outing, how much alcohol will I need to just boil water for 2 meals a day for 2 days?

[Ken Helwig]

I usually bring 4 oz. Usually an once is enough to boil water.

wt is related to specific gravity of the liquid which also is related to the temp at which it is measured.

specific gravity is a dimensionless measurement which is defined as the ratio of density of the material to the density of water at a specified temperature.

specific gravity is often expressed as:

SG = ρ / ρH2O

where

SG = specific gravity

ρ = density of fluid

ρH2O = density of water

it’s common to use the density of water at 4 deg C as a reference. this is the temp at which the density of water is at the highest.

therefore, wt varies slightly depending upon type of alchohol & temp conditions.

w/o going into more precise detail, which prob. isn’t necessary for your purposes, figure, roughly, alcohol weighs ~80% of what a similar volume of water weighs.

since we’re talking of “rough”, or approximate, values this applies to both ethyl alcohol & denatured alcohol.
