How to state fractions with units of measurement? (e.g. 0.75 lb, 1.5 lbs, 1.75 lbs, etc.) "1 lb" is 一磅 and "half-pound" is 半磅. And "3/4" is 四分之三. So far, so good.

But I'm not clear on how to read measurements like 3/4 lb, 1.5 lbs and 1.75 lbs in Chinese. My guesses below would be:


3/4 lb = 四分之三磅
1.5 lbs = 一個半磅
1.75 lbs = 一個四分之三磅 (?) - This is the one I'm most confused about. I'm not totally sure how to string together all the elements


Also, I'm specifically using pounds as the unit of measurement here because I live in the US and I frequently need to state fractions of a pound, but I'd be curious if there are any relevant differences with other units of measurements, in particular grams and kilograms.
在中文里他们正确的读法是下面这样：


3/4 lb = 四分之三磅
1.5 lbs = 一点五磅
1.75 lbs = 一点七五磅
