A lot, a lot of supermarkets.

The items with a net content of 200 grams are: a pack of plums, a bag of 200 grams of sugar, a pack of tissues, a bag of 200 grams of candy, etc.
Net content, which refers to the amount of the product inside after the packaging container and other packaging materials are removed. Regardless of the packaging material of the product, or any other material that is packaged with the product, it shall not be recorded as a net content.
Object, a Chinese word, pronounced wù pǐn, is a commonly used concept in the fields of production, office and life, which generally refers to various things or sporadic items, as well as material materials involved in physical flows in economic activities.

The net content of 100 grams includes: instant noodles, facial cleanser, milk, biscuits, water, lotion, special laundry detergent, toilet paper and other items. These products are quantitatively packaged and belong to quantitative packaging products.
The so-called quantitative packaging goods refer to all pre-packaged goods that are for the purpose of sales, closely related to the interests of consumers, and have a unified quality, volume and length within a certain limit. This provision cannot be applied to medicines, electrical appliances and other goods.

In life, edible oil, purified water and other packaged items have a capacity of one liter, and the net content of these items is the concept of one liter.
A liter is a volumetric unit, which is converted into a volumetric unit as a cubic decimeter and cubic meter.
A liter, often abbreviated as a liter, is a unit of measurement for capacity with the symbol L. In the past, lowercase handwriting was used as a symbol, but due to the inconvenience of printing, the uppercase printing L was used instead, noting that milliliters can still be expressed as ML, and the liter itself is not an International System of Units (SI) unit, but it is a metric unit, and it is a unit that accepts to be used in conjunction with SI.

Liquids such as milk, beverages, salad oils, etc., are measured in liters.

The net content of 1 kg is 2 catties. kg is the code name for kilogram, which is a unit of weight. 1kg is one kilogram, and one kilogram is equal to two catties.
kg (kilogram) is a unit of weight, 1kg = 1000g = 1 kg = 2 catties. Example: The net content of laundry detergent sold in supermarkets: 1kg, which means 1 kg, which is converted into 2 catties.
Nature of the Kilogram:
The kilogram is a unit of mass, and mass is equivalent to how "heavy" something is in everyday life. However, mass is actually a property with "inertia"; That is, an object will tend to maintain its pre-existing velocity in the absence of external forces. When an object with a mass of one kilogram is subjected to a force of one newton, it gains an acceleration of one meter per square second.
The weight of the matter depends entirely on the strength of the local gravitational force, while the mass does not change (assuming that the mass does not move relative to the observer at relativistic velocity). Correspondingly, astronauts in microgravity do not need any force to lift objects inside the capsule; Because the object "has no weight".
However, the object retains its mass under microgravity, and the astronaut needs to exert ten times the force to accelerate the object with ten times the mass with the same acceleration.

Something that weighs 500 grams has:
1. A bottle of 500 ml of mineral water.
The density of water is 1g cm, and 500 ml is 500cm, so the weight of a bottle of 500 ml of mineral water is 500 grams.
eggs. 1 egg weighs about 50 grams, so 10 eggs weigh about 500 grams.
3. Two cartons of Tetra Pak boxed milk.
If 1 carton of Tetra Pak milk weighs 250 grams, then two cartons of Tetra Pak milk weigh 500 grams.
4. A bag of edible salt.
The weight of a bag of edible salt in everyday life is 500 grams.
apples. In daily life, the weight of 1 apple is about 125 grams, and the weight of 4 apples is about 500 grams.

Brother: That's not a good question.
First of all, you have to look at the production date, the closer the better, and secondly, the protein mass, the percentage, if you have to look at the fat content during the ** period, which is low, if you are really entangled, just throw a coin. >>>More
