When it comes to building healthier habits around alcohol, knowledge truly is power. Understanding what you're drinking—and how much—is the first step in regaining control. That’s where the Free Drink Calculator from Rethink Drink becomes invaluable. Whether you're just becoming sober curious or actively using the Sinclair Method, this simple, user-friendly tool offers a vital layer of insight.

Why Knowing Your Alcohol Units Matters

In the UK, alcohol is measured in units, with each unit representing 10ml of pure alcohol. However, with the vast variety of drink sizes and strengths, it’s easy to underestimate your consumption. Here’s how typical drinks stack up:

• A pint of lager (4% ABV, 568ml) contains roughly 2.3 units

• A 175ml glass of wine (13% ABV) has about 2.3 units

• A 25ml shot of spirits (40% ABV) equals 1 unit

These can quickly add up, especially if you’re drinking regularly or serving yourself at home.
