500ml Beer: Grams of Alcohol at Every ABV
A 500ml 5% beer has 19.7g of ethanol — 1.4 US standard drinks. Enter your exact beer into the calculator for a personalised BAC estimate.
Calculate Your 500ml Beer BAC →The 500ml can or bottle is the standard format for many European lagers and craft beers. It is exactly 50% larger than a 330ml can — but the alcohol content depends entirely on the ABV. At 5% ABV, a 500ml beer contains 19.7g of ethanol. At 8% ABV (a common craft beer strength), that same can holds 31.6g — more than two US standard drinks.
How to Calculate Grams in a 500ml Beer
Using the standard grams formula: 500ml × ABV (decimal) × 0.789 = grams of ethanol. For 5% ABV: 500 × 0.05 × 0.789 = 19.7g. For 6%: 500 × 0.06 × 0.789 = 23.7g. The 0.789 constant is the density of ethanol at 20°C — see why 0.789 matters.

Grams = 500 × ABV × 0.789. US standard drink = 14g, UK unit = 8g. BAC at peak before metabolism (Widmark formula).

Calculate Your BAC from a 500ml Beer →How Many 500ml Beers Before You Hit 0.08 BAC?
The legal driving limit in the US is 0.08% BAC. At 5% ABV, one 500ml beer raises BAC by about 0.041% for a 70kg man. Two beers (39.5g) produces approximately 0.083% — barely over the limit. For a 60kg woman at 5%, one 500ml beer approaches 0.060% and two beers reaches 0.119% — well over the limit.
For higher ABV beers, the numbers are more dramatic: one 7% 500ml beer (27.6g) puts a 70kg man at 0.058% — a single can approaching the EU driving limit of 0.05%. Two of these beers hits 0.116%.
Comparing 500ml Beer to 330ml Can
| ABV | 330ml Grams | 500ml Grams | Difference | Extra US Std Drinks |
|---|---|---|---|---|
| 4% | 10.4g | 15.8g | +5.4g | +0.39 |
| 5% | 13.0g | 19.7g | +6.7g | +0.48 |
| 6% | 15.6g | 23.7g | +8.1g | +0.58 |
| 7% | 18.2g | 27.6g | +9.4g | +0.67 |
500ml Beer and UK Units
In the UK, one unit = 8g of ethanol. A 500ml beer at 5% ABV contains 19.7g = 2.5 UK units. UK guidelines recommend no more than 14 units per week for adults. That means just 5-6 standard 500ml lagers per week reaches the weekly recommended limit. Always check labels — many premium lagers sold in 500ml cans are 5.2% to 5.5% ABV, adding another 0.3–0.6g per can.

How many grams of alcohol in a standard 500ml lager?
A standard 500ml lager at 4% ABV contains 15.8g of ethanol. At 5% ABV (the most common premium lager strength), it contains 19.7g. Always check the specific ABV on the can — it varies significantly between brands and can be 3.5% to 7%+ for craft varieties.
Is a 500ml 5% beer more than one US standard drink?
Yes — at 19.7g, it is 1.41 US standard drinks (14g each). Many people think of a can of beer as "one drink," but a 500ml 5% lager is nearly one and a half standard drinks. This underestimation is a key reason why people miscalculate their BAC.
Does chilling a 500ml beer affect the alcohol content?
No. Chilling changes the temperature but not the ABV or the amount of ethanol in the can. The density of ethanol changes slightly with temperature (see ethanol density article), but this has no practical effect on BAC calculations. The label ABV is what matters.
