This depends on what you are measuring.
There is "Dry Cup"(a cup of a solid material) and "Liquid cup" (cup of a fluid or liquid).
However, a cup (dry or liquid) is classified as a measurement of volume.
1 cup = 250 milliliters or 8.80 liquid ounces
What is the most suitable instrument for measuring the weight of a cup
A cup is a measure of volume and a gram is a measure of mass. I found that a cup of almonds is about 108 grams in weight, So does a Walnut weigh more than an Almond? They probably weight exactly the same.
An ounce is a measure of weight A cup is a measure of volume. The two can not be equated.
A cup is a measure of volume, and dry ounces is a weight, The only way one can determine the weight of a substance that will fit into a specific volume is to measure the specific substance.
It would all depend on what you are measuring
kilograms
You can measure its volume with a measuring cup or measuring spoons. You can measure its weight with a food scale. You can measure its temperature with a thermometer.
Usually a scale. Get the weight and convert to mass.
A cup is a measure of volume. Oz is a volume of weight. An cup of oil will be fewer oz than a cup of thick syrup.
Cup is a measure of volume, gram is a measure of weight. There is no direct conversion between the two, it is different for each commodity and depends on density.
First you have to determine how much the cup weighs without the vegetables. Then you weigh it with the vegetables and subtract the weight of the cup.
1 cup is 250 gm. -So 100 gm is 2/5 of a cup.
