What items in the home are represented by their quality in grams?

There are many such items, such as table salt, **, tea, etc.

When visiting the supermarket, people can see various names of table salt on the shelves, such as well salt and lake salt.

Sea salt, rock salt, coarse salt, bamboo salt, rose salt.

Wait. Some salt is often considered by consumers to be "high-grade salt" because of its high **, and even superstitious about its health value.

According to the first grade of raw materials for salt production, salt is generally divided into well salt, lake salt, sea salt, rock salt, etc. Well salt refers to salt made by drilling wells to extract underground brine (naturally occurring or produced after salt mine water injection); Sea salt refers to the salt produced by the evaporation and crystallization of seawater.

Lake Salt is from the salt lake.

The salt is directly mined in the salt pans, and the salt lake brine is used as raw material in the salt pans.

salt; The sea salt produced after the sun dries the seawater, and the "salt fossils" formed by hundreds of millions of years of geological extrusion and underground high temperature are called rock salt.

According to the purity after purification, table salt can also be divided into coarse salt and fine salt. Coarse salt is not purified and has many impurities and large particles, while fine salt is purified and has few impurities and small particles. The so-called impurities are mainly minerals, which is why coarse salt contains more magnesium, potassium, calcium, etc. than fine salt.

Seasonings used in cooking. Tea and drinks, such as cassia or chrysanthemums, can be expressed in grams. There is also **** jewelry can be expressed in grams.

1. Paper 2. Sponge.

3. Thumbtacks. 4. A dime.

Gram, for the unit of mass, symbol g, the weight of one gram is approximately equivalent to the mass of one cubic centimeter of water at room temperature.

1 ton = 1,000,000 grams (one million grams) 1 kilogram (1 kilogram) = 1,000 grams (one kilogram)[1]1 kilogram = 500 grams (1 gram = kilogram) 1 milligram = gram (1 gram = 1000 milligrams).

1 microgram = 001 gram (1 gram = 1000000 micrograms) 1 nanogram = 000 001 gram (1 gram = 1000000000 nanogram) We know that there are objects in life that are heavy and some objects that are light. When we weigh heavier objects, we use kilograms as units, so when we weigh lighter objects, what should we use as units, grams to weigh lighter objects.

20 drops of water is just 1g, and one drop of water is about.

A dime coin is a little more than a gram.

A chalk head, a drop of water

According to the provisions of the method of using legal units of measurement in the People's Republic of China, China's legal units of measurement are based on the SI system of units, and some non-SI units are selected. The SI hail position of the mass is kilograms.

In this standard, mass is expressed in the derived unit "gram" (g) of the SI unit kilogram.

Since the international jewelry industry usually uses carat (abbreviated CT, 1g=5ct) as the unit of measurement for jewelry and jade, this standard stipulates that carat can be used as a reference value for the quality of jewelry and jade. When used, the carat value equivalent to the gram can be indicated in parentheses after the gram, such as: This means that it not only conforms to the provisions of the legal unit of measurement, but also adapts to the best habits.

It is worth mentioning that, according to the custom of the activity, the carat value only describes the quality of the jewelry jade itself. The mass of the inlaid metal or other substance cannot be expressed in carats, but only in grams or kilograms. The quality of the jade inlaid in the jewelry can be expressed in the form of gram after carat value, but the total quality of the jewelry itself can only be expressed in grams.

The first gram is more appropriate, the gram is a relatively small unit of mass, and the first group of the three groups [a banana] has the smallest mass, so the first group is chosen.

It can be used to measure the number of microscopic particles, and it can be related to mass. It connects the macro and the micro.

The mass of the paper is calculated in grams by taking a sheet from a plywood and weighing it without cutting it.

The general copy paper is 80 grams of paper, the general machine-readable card (college entrance examination objective question answer paper) is also 80 grams of paper, and there are 90 grams of paper, and the registration card is generally 100 grams of paper.

There's no step, you just have to go to the paper selling place, buy a sheet of paper, go home, fold it, and weigh it on a scale.

Prepare 100 sheets of paper.

Weigh out 100 sheets of paper with a mass of m

The mass of a piece of paper is m divided by 100.

Tell you a way to know the mass of an A4 sheet of paper by calculating without measuring.

When buying the A4, it is marked with 80g m 2, 70g m 2, 60g m 2, etc., while the size of the A4 is 21cm

For example, 80g m2 of A4 paper can be calculated as a mass of about 5g

Because the specification is 890mm 1240mm, you can calculate the area of a single sheet of paper, and then multiply it by 55g m2, that is, the weight of a single sheet of paper, the unit is g (gram): 0 890m 1 240m 55g m2=60 698g Of course, this value is often not accurate, the quality of a piece of paper is often lighter, so you can measure the quality of 100 or more sheets of paper, and then divide by the number of sheets, you can get the quality of each sheet!

Take a stack of paper and weigh it on a scale, and divide the resulting mass by the number of sheets equal to the mass of a piece of paper.

I'm a stationery maker, QQ tell me? Tell you slowly.

Just use the first floor to measure more and calculate less.

I don't feel right, because you're not professional enough, and it's hard to tell the difference between 20 grams, 30 grams, and 50 grams.
