In the SI we use the submultiple gram (g).
Usually a scale. Get the weight and convert to mass.
What is the most suitable instrument for measuring the weight of a cup
A thermometer is typically used to measure the temperature of a cup of tea. These thermometers can be digital or analog, and they provide an accurate reading of the tea's temperature.
Grams measures mass... but cups is a measurement of volume.
A common instrument that can measure both mass and volume is a laboratory balance. The balance can measure the mass of an object by comparing it to calibrated weights, while volume can be indirectly determined by measuring the displacement of a liquid when the object is submerged.
There are a few instruments that can theoretically be used to measure flour. The most common measuring tool is a measuring cup.
The answer will depend on the object that you wish to measure. For example, a balance and some standard masses (wrongly called weights) will be OK for measuring the mass of a few apples but not much use for the mass of an elephant and totally useless for the mass of the sun! In the latter case, the tools are spectroscopy and computers, with physics and mathematics as intellectual tools.
use a measuring cup
Neither. Millilitres measure volume not mass. Grams measure mass
you use a measuring cup to measure stuff. mostly cooking. Answer: you can use a dry measuring cup, or a liquid measuring cup. you use liquids such as water or veggie oil. for dry measuring cups, you put in dry stuff, such as baking flour or sugar. all you have to do is put the substance in and read the number. talk about easy and simple to use!!!
A graduated cylinder or a measuring cup is typically used for measuring liquids. These instruments have marked increments to help accurately measure volumes of liquid.
the tool you use to measure milk in your cereal would be the measuring cup
