What 57.5% ABV means in proof
US proof is twice the alcohol by volume, so a spirit at 57.5% ABV is 115 proof. To reverse it, divide the proof figure by 2 to read back the ABV.
If you are diluting or blending to hit 57.5% ABV, confirm the final strength with an alcoholmeter at 20°C rather than trusting the calculation alone, since ethanol and water contract slightly when mixed.
Confirm the real strength: proof printed on a label is one thing, the spirit in your jar is another. A 0 to 200 proof alcoholmeter reads it directly at 20°C.

Common questions
What is 57.5% ABV in proof?
On the US scale 57.5% ABV equals 115 proof. US proof is exactly twice the alcohol by volume, so multiply ABV by 2.
Why is proof double the ABV?
It is a US convention. The US sets proof at twice the alcohol by volume, so 50% ABV is 100 proof. Other historical scales used different ratios.
