measuring cup
A measuring cup , also known as a liter , is a measuring vessel with which liquids and food can be measured.
Appearance
Measuring cups can be made of metal or glass , but plastic measuring cups are the most common . For metal, the measurements are on the inside, for transparent glass and plastic on the outside. Depending on the type of loose food to be measured, the distances between the measuring lines and the units of measurement differ. Liquids are given in liters or cubic centimeters, the reading is always at the level of the horizontal liquid level, the so-called meniscus , in the case of aqueous liquids at the lowest point. In order to avoid reading and measuring errors, the observing eye should be in a plane to the liquid level (i.e. the measuring vessel is raised accordingly or the viewing point of the eye is lowered, "looking down at an angle" falsifies the result).
For the preparation of cocktails there are special measuring cups, which are called jigger or German bar measure and usually only have a small volume (up to about 60 ml).
Measuring beakers are often cone-shaped , since the absolute reading error is smaller when the filling quantity is lower than with a cylindrical shape.
Such measuring beakers can also be calibrated with the volume of parts by weight , for example "Sugar scale: 100 g, 200 g, ..." or "Flour: 100 g, 200 g, ...". Such measuring beakers previously saved the purchase of (expensive or space-consuming) kitchen scales and can help save time during preparation. Typical bulk goods for this use are flour, rice or sugar.
Measuring cylinders or calibrated beakers are often used in industry and science . In the chemistry laboratory, measuring beakers used to be referred to as the scale , especially those without a scale.
