A piece of metal or piece of metal placed at one end of the balance as a weight standard, each of different sizes, has a certain weight.

A physical gage with a given quality and a defined shape. It is used for the verification of scales and for weighing on scales. A weight must be combined with a balance or scale (the weight used on the scale is often called a weight) before it can be used to determine the mass of other objects, so it is a subordinate physical measuring tool.

In China, the "right" equivalent to a weight appeared in the Xia DynastyFor more than 4,000 years after that, different dynasties had different shapes and materials of "power" as measuring tools.

In modern mass measurement, weights are standard gauges for the transfer of mass values. The mass value is based on the actual platinum-iridium alloy kilogram prototype stored in the French International Bureau of Weights and Measures as the only reference. All countries divide weights into national kilogram benchmarks, national kilogram sub-benchmarks, kilogram working benchmarks, as well as working reference groups composed of multiples and components of kilograms and various working standard weights.

There is only one national kilogram benchmark for each country. China's national kilogram reference is the platinum-iridium alloy kilogram reference weight numbered 60 certified by the International Bureau of Weights and Measures in 1965. The national kilogram datum and the national testimonial datum, the national kilogram sub-datum, the kilogram working datum and the standard weight constitute the mass value transmission system.

In order to measure a variety of objects of different masses, the kilogram working datum is equipped with a set of working datum groups composed of its multiples and components, with the largest to the smallest number of masses and can form any quantitative value. The working reference group and standard weights are usually divided into kilogram group (1 20 kg), gram group (1 50 g) and milligram group (1 500 mg), and there can also be micro gram group or other weight combinations (such as the weight increase group used on the bench scale) as neededWeights are usually in the form of a combination of and

When using, you can't pinch it by hand, you can only use tweezers to clamp it.

A physical tool used to measure the weight of an object on a balance (the object is placed on the left side of the scale, and the weight is placed on the right side of the scale).

Explanation of weights.

1) [makeweight] Something that adds weight to a scale (2) [weight used on a balance] means a piece of metal or other material with a precisely defined weight that is used to weigh other objects (e.g. in a balance) For a detailed explanation, see "Weight".

Word decomposition Explanation of weight on a balance as a weight standard Something made of metal, also known as the "fama" in the chain. radical : stone; The interpretation of the code refers to the symbol that calls the sensitive code (code) ǎ which represents the number:

yards (a number symbol; b round chips; c The financial community claims to be able to dispatch cash). Number. Page number.

Price. The tool used to calculate the quantity: chips.

Weight. Refers to one thing or class of things: these are two different things.

Anglo-American units of length,

Weights are standard comm gages for mass value transfer. The main rough is to be used for the verification of the scale and the measurement on the scale, so that the rock front is useless. Common balances.

Weights are one of them, which can be used to weigh more accurate masses.

砝码 [ fǎ mǎ ].

When weighing things with a balance, the standard used to calculate the amount of heavy rot is made of slag or metal such as copper and lead, and there is a difference between light and heavy. It is also used as a law horse and a law code.

Weight. It is a standard reference for the holder of the measurer.

Generally, it is made of metal 1g, 5g, 10g, 50g, 100g, and so on in different weights.

As a reference for calibrating balances or bench scales.

Analysis: Weights are divided into datum and various grades of standard weights, at present, China has been in line with the international metrology organization, using kilogram system kg

1 International Kilogram Prototype: It is a cylinder with a diameter of 39mm and a height of 39 mm, it is composed of a platinum-containing 90% and iridium-containing 10% platinum-iridium alloy cylinder, with a density of approximately 10%, and it is the international benchmark kilogram prototype of the International Bureau of Weights and Measures (BIOM). It is stored at the headquarters of the International Bureau of Weights and Measures in Paris, and all measurements should be traced back to the original kilogram.

2 China's kilogram working prototype: all kinds of other domestic weights are passed down by the kilogram prototype.

The mass of NO60 is 1kg, and the mass of NO64 is 1kg.

3 Standard weights are divided into: e1 e2 f1 f2 m1 m2 m3 m1-2 m2-3

M-level is generally used for the identification of ** scales.
