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 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.
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.
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.
1 cup is 250 gm. -So 100 gm is 2/5 of a cup.
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.
