    This is not shrinkflation.

    440ml is a UK variant. No one has a confirmed explanation for its existence alongside 500ml, but it’s been around for decades.

    However 440ml of water would be 0.44kg which is just under one pound imperial weight (0.45kg). Presumably the fluid plus the aluminium can would weigh about 1lb which may explain the odd volume measure (given transport costs are often by weight and possibly even how customs costs may have used to work?).
