This question cannot be answered sensibly. A km (kilometre) is a measure of distance, with dimensions [L]. A gram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
600g is equivalent to approximately 1.32 pounds.
600g
600g = 21.2oz
usually around 800 grams
That is approximately 2.7 cups.
600g is equal to 0.6 kilograms.
600 grams = 21.16 ounces
5 kg is greater (it is equal to 5000g)
0.6kg = 600g
There are approximately 1.32 pounds in 600 grams.
It depends on the liquid. At room temperature and sea level 600ml of water weighs 600g. 600g is 1.3lbs. If your 600ml is denser than water then it'll be more, if it's less dense it'll be less.
Still 600g unless you take it more than once. If you take 600g once a year in 10 years time it will be 6000g aka 6kg. I have a feeling you missed adding something to the question.
