# How do you ask something which is not exactly "half a glass"?

Please, fill half a glass of water/tea.

Well, the context for the above sentence is understandable. But, what if I need to ask the same, where

Cases:

1. The tea/water is more than half but not full.

2. It is less than half but neither empty nor very little.

Do we have any words/sentences to express for these two cases? I guess we can't say:

Please fill 25% or 37% of tea OR 75% of water

• Not sure how filling 37% percent of water in a glass is possible... Commented Feb 9, 2022 at 9:13
• Filling half or a third/fourth/three-fourths of a glass with water is more standard. Commented Feb 9, 2022 at 9:15
• 'Give me a drop' would be colloquially understood in UK English as just a small amount of liquid in a glass - if it was water or a soft drink. Unfortunately 'Give me a drop' when applied to alcoholic drinks might mean the same, or might mean 'fill my glass'!

• "Give me some water." Or you could say "Just fill it a quarter of the way up" or something. You could say "Give me 375 ml" or "fill it 67% full", that's certainly grammatical. People might wonder why you were being so precise (unless you were making a recipe or were a chemist or something), but that's outside the scope of English Language and Usage.

• @Justin - weigh the glass full and empty, do some simple arithmetic, pour until the desired weight is reached. Commented Feb 9, 2022 at 14:34
