How much alcohol (40%) corresponds to 33 cl of beer with 7.2 percentage alcohol by volume?
“The amount of [...] pure spirits (40 %) that a strong beer or a glass of wine corresponds to [...] can be calculated with a formula (percentage by volume * the volume in cl * 0.025).” (MHF)
7.2 * 33 * 0.025 = 5.94 cl (round up to 6 cl)
(0.025 is the same as dividing by 40)
There is also a driving licence book online (2022).
