How many glasses are in 1 liter of water?
When you read the advice about ‘drinking 8 glasses of water per day,’ they are speaking about 8 ounces of water per glass. That’s a very common, standard measurement, almost like ‘cup’ in cooking terms.
Yes, there are glasses that vary from that 8 ounce capacity, and you could try to figure it out by starting with the capacity of your glass, and use math, but let’s just be sensible, shall we?
So, 4 (8 ounce) glasses, plus a little more, will come to 1 liter. 2 liters will get you to your 8 glasses of water per day, with a little extra.
