A conventional measuring cup usually has one or more scale markings used to designate one volume or several volumes. A conventional measuring cup is usually in the form of a cylinder. A conventional measuring cup is used in kitchens to measure food products during food preparation. 
     A conventional measuring cup is used to measure dry ingredients such as flour and sugar, and liquids such as milk and water. Conventional measuring cups are not practical for measuring prepared foods such as mashed potatoes and gravy, hot oatmeal, cooked pasta and cheese sauce or rice pilav. Prepared foods such as these stick in measuring cups and are difficult to remove. Repeat use of the same measuring cup for different food products can result in cross contamination. Hot food can become cold during transfer from a measuring cup to a serving plate or to a serving bowl. 
     Conventional measuring spoons are used for measuring dry or liquid food products. Conventional measuring spoons are not intended for measuring large portions of food. Dried pasta measuring tools are limited to measuring dried pasta. They are not designed to measure a multitude of food products. Dried pasta measuring tools lack the capacity for measuring foods such as oatmeal, mashed potatoes or rice.
