Question: how many litres are in a glass of water?
Answer: The larger your glass is, the fewer glasses it took. But while researching on it, I found a website named 'CalculateMe '. So, according to CalculateMe, 1 glass of water is near about 0.14786765 Liters. And if this amount is absolutely correct, it will take around 7 (6.7628045) glasses for 1 litre of water.
