There is a difference between the metric system and the municipal system: the feed rate of the metric unit is 1000, 1 ton = 1000 kg, 1 kg = 1000 grams. The current rate of the municipal weight unit is 10, 1 catty = 10 taels, 1 tael = 10 money.

In ancient times, each country had its own unit of measurement, the ancient Chinese unit of weight, jun: thirty catties is one jun, ten taels weigh one baht, twenty-four baht weighs one tael, and sixteen taels weigh one catty. China has a specific unit of measurement, catty, the international unit of measurement, kilograms, tons, the United States, Britain pound and so on.

There are also grams, micrograms, milligrams, kilograms, and tons.

Microgram: unit of mass, symbol g, 1 microgram is equal to one millionth of a gram, 1000 micrograms = 1 milligram, 1000000 micrograms = 1 gram, 1000000000 micrograms = 1 kilogram.

Milligram: A unit of mass, symbolized mg, is one thousandth of a gram. 1 mg = 1000 mcg, 1000 mg = 1 g, 1000000 mg = 1 kg.

G: The symbol g, equal to one thousandth of a kilogram. The weight of one gram is about the same as the mass of one cubic centimeter of water at room temperature, which is about the mass of a swastika folder. 1 ton = 1,000,000 grams, 1 kilogram = 1,000 grams, 1 milligram = grams, 1 microgram = grams.

Kilogram: also known as kilogram, is the international basic unit of mass, the symbol kilogram = ton, 1 kilogram = 1000 grams, 1 kilogram = 1000000 milligrams, 1 kilogram = 1000000000 micrograms.

Classification of the unit of measurement and the rate of progress of primary school mathematics.

1) Length unit of measurement and rate: kilometers (km), meters, decimeters, centimeters, millimeters 1 km = l kilometers 1 km lead Youheng = 1000 meters l meters = lo decimeters 1 decimeter = lo centimeters l centimeters: 10 mm.

2) Area measurement unit and rate: square kilometers, hectares, square meters, square decimeters, square centimeters 1 square kilometer = 100 hectares l square kilometers = 1,000,000 square meters l hectares = 10,000 square meters 1 square meter = square decimeters 1 square decimeter = 100 square centimeters.

3) Volume volume measurement and progress rate: cubic meters, cubic decimeters, cubic centimeters, liters, milliliters l cubic meters = 1000 cubic decimeters 1 cubic decimeter = 1000 cubic decimeters l cubic decimeters = l liters 1 cubic centimeter = l milliliters.

4) Quality Huai do unit and advance rate: ton, kilogram, kilogram, gram 1 ton = 1000 kg 1 kg = 1 kg 1 kg = 1000 grams 5) time unit and advance rate: century, year, month, mountain day, hour, minute, second l century = 100 years 1 year = 12 months (31 days of the month has a month, 30 days of the month has a month, 28 days in the common year of February, 29 days in the year of Run) 1 day = 24 hours 1 hour = 60 minutes 1 minute = 60 seconds.

Weight units include grams, kilograms, and tons, and the rate of advancement between them is 1000.

1 gram = kilogram.

1 kg = ton.

1 gram = ton. Convert small units into large units, and move the decimal point to the left;

Convert large units into small units, and move the decimal point to the right.

The advance rates between weight units are as follows:The rate of advance between commonly used weight units is 1000 or 1000 to the nth power.

The following is an example: Tons (t) = 1000 kilograms (kg). Li Zhu.

Kilogram (kg) = 1000 grams (g).

Grams (g) = 1000 milligrams (mg).

Milligrams (mg) = 1000 micrograms (g).

Tons (t) = 10000000 = 1000 2 grams (g).

The common rate of advance between several units of weight is 1000 or 1000 to the nth power. When converting, the unit of the small Qi sum is converted into a large unit, and the decimal point is shifted to the left; Convert the large high bare unit into a small unit, and move the decimal point to the right.

For example: 1 gram = kilogram, 1 kilogram = ton, 1 gram = ton; 1 ton = 1000 kg, 1 kg = 1000 grams, 1 gram = 1000 mg, 1 mg = 1000 micrograms, 1 ton = 10000000 grams.

1000。The rate of progress between the weight units is 1000, the weight unit, has a long history, in ancient times, each country has its own unit of measurement, the ancient Chinese unit of weight, China has a specific unit of measurement catty, the international unit of measurement kilogram, ton and so on. A unit of measurement is a scalar quantity defined and adopted according to an agreement, with which any other quantity of the same kind can be compared so that the ratio of two quantities is expressed as a number.

Units of measure have names and symbols that are given according to convention.

The density unit includes kilograms, cubic meters and gram rolling ridges, cubic centimeters, and the advance rate of density units is: 1 kilogram 1 cubic meter = 1000 grams 100000 cubic centimeters = 1 1000 grams cubic centimeters; grams cubic centimeters = 1000 kilograms cubic meters. The physical meaning of density is that a property of matter does not change with the change of mass and volume, but only changes with the change of the temperature and pressure of the state.

The ratio of the mass of a substance to its volume, that is, the mass of a substance per unit volume, is called the density of such a substance.

Density is the mass per unit volume. The SI unit is kilograms per 100 cubic meters (kg m), and grams per cubic centimeter (g cm) are also commonly used. For liquids or gases, kilograms per liter (kg l) and grams per milliliter (g ml) are also used.

But G l is generally not used. grams of cubic centimeters, degrees of kinian centimeters or kilograms of cubic meters. kg/m³。
