Heineken vs Grolsch show different alcohol units for the same volume and strength beer

One of them is wrong

I bought two cans of beer today. A 500ml can of Grolsch 5% and a 500ml can of Heineken 5%.

The Golsch says it contains 2.5 UK units unites of alcohol but the Heineken says it contains just 2.0 UK units.

So which is correct and why are they different in the first place??
