4 cm is not a unit appropriate for measuring volume.
i got 1.95 g/cm. (grams=7.8)
It depends on the density of steel. There are many types of steel depending on what substances are alloyed together. The density of stainless steel can range from 7.5 to 8 grams per cm3. But there are other types of steel that are denser or lighter.
grams
i would say 150 grams
Cups measure volume and grams measure weight, so you can't make an equivalence without specifying what you're measuring, since the densities will vary. 100 grams of steel nuts and bolts, for example, would barely cover the bottom of a cup, while 100 grams of cotton wool would fill several cups.
An onion would typically be measured in grams, as it is a smaller unit of measurement suitable for measuring the weight of individual onions.
I would use a measuring cup. 175 grams of flour is about 1.4 cups.
When measuring flour, 409 grams would be equal to 1.73 cups. One cup of flour would be equal to 236.59 grams.
It is measured in grams.
I would say grams
Grams.
There are 1,000,000 grams in a kilogram. Since 'km' is not a standard unit for measuring weight, the conversion to grams would depend on what you are measuring.
