Scoop measure
A ladle measure is a vessel with a known volume , which is used as a measure of volume, weight or quantities of liquids and bulk goods .
The volume of scoop measures is usually in the range from 0.5 to 2000 cm³. Baskets that are used to measure fish and coke for domestic use are considered to be particularly large ladle sizes in the broader sense .
Scoops are completely immersed in liquids or bulk solids in order to fill them completely. In the case of bulk goods, the measure can also be used to "scoop" through the bulk goods in order to fill them; it is also possible to pour in from other containers.
Scoop measurements can be made from all conceivable materials, such as B. wood , metal , plastic , glass , porcelain , but also made of bones, etc. be made. Vessels and hollow bodies that originally served a different purpose have been used as scooping measures ( cartridge cases , tin cans ). Smaller dimensions are often provided with a handle for better handling. The shape of the measure mostly corresponds to a cylinder closed at one end .
In addition to being used for liquids of all kinds, scoop measures are widely used for animal feed and food , such as. B. grain , nuts , coffee (see coffee scoop ), etc. Also for measuring propellant powder for muzzle-loading weapons and cartridge ammunition as well as for measuring shot for hunting were and are common. For these purposes in particular, dimensions are also known which had an adjustable volume that was implemented by regulating a floor screw.
When using scoop measures, there are special features in individual cases:
In the case of liquids, the mass of the liquid is always equal to the volume multiplied by the density of the liquid.
In the case of bulk goods, the mass in the scoop measure is heavily dependent on how the measure is handled. Depending on how the measure was filled, possibly also from what height the bulk material was filled into the measure, whether the measure was shaken, knocked or exposed to vibrations , the mass is always different, depending on how dense the grains of the Bulky goods lie against each other in measure. It should also be noted that the mass resulting from a certain volume cannot simply be converted to another volume ( granular matter and its physics ). When measuring bulk goods, the "mountain" (protrusion) is always wiped off with a suitable object ( squeegee ) to ensure constant conditions. The accuracy of the scoop measurements is high if the working method is careful and consistent.
When preparing food in the kitchen, cups , glasses (e.g. “shot glasses”) or other small vessels are often used as measuring points for different ingredients. They often do not have a precisely known volume, but it is usually known what effect and property the measured amount has on the total amount of food to be prepared. Spoons of different sizes and the knife tip often mentioned in recipes are ultimately scoop measurements (the latter very imprecise).
