My friend recently flew with KLM and got a 86 ml water bottle and 187 ml of wine. Why those numbers? I couldn't find a reasonable conversion...

    A bottle of wine is usually 750 ml so that's a quarter-bottle. But is this a question about travel? It's like asking why they showed a particular movie. – Weather Vane Nov 24 '18 at 9:40
  • Technically the wine bottle should have been 187.5 ml which is a quarter bottle, also known as a piccolo. No idea about the water though as that is not an obvious fraction of a litre. – mdewey Nov 24 '18 at 13:50

    I'm voting to close this question as off-topic because it's not about travel, although asking about the size an airline's beverage service container. However, it may be pure physics: how many will fit on a beverage cart and how many are required for each flight, and how much weight do they contribute when full. – Giorgio Nov 24 '18 at 14:52

After a lot of googling, I just visited the manufacturer web site and it seems like te container was designed and then measured to get te right amount printed on. 100 containers with box is exactly 10 kg now.

What the manufacturer says.

    I think it is the other way around, they wanted a water cup that fits in the coffee cups they hand out at some meals. Since then they use it at all flights where water is served as standard. – Willeke Nov 25 '18 at 9:27
