water to add = volume × (current ABV − target ABV) ÷ target ABV
= 1000 × (60 − 46) ÷ 46 = 304 mL per litre

About this dilution
60% sits in the high-strength range often used before final reduction, while 46% is a popular non-chill-filtered bottling strength favoured by craft distillers. Bringing 60% down to 46% means adding roughly 304 mL of water for every litre of spirit, increasing the batch to about 1304 mL.
For casual reduction the standard volume method above is accurate enough. When bottling at an exact legal strength, switch to OIML Precise mode in the calculator, which corrects for the slight volume contraction that occurs when ethanol and water mix.
Verify before bottling: a calibrated alcoholmeter is the only way to confirm you have hit 46% ABV. Measure at 20°C.

Common questions
How much water do I add to dilute 60% ABV to 46%?
Add roughly 304 mL of water to each litre of 60% spirit to reach 46% ABV. The formula is water to add = volume times (current ABV minus target ABV) divided by target ABV.
Why should I verify the result with a hydrometer?
Ethanol and water contract slightly when mixed, so the real strength can sit just under the calculated figure. Always confirm with a calibrated alcoholmeter at 20°C before bottling.
