What are the units of length

Commonly used units are millimeters (mm), centimeters (cm), and decimeters.

dm), kilometers (km), meters (m), micrometers (m), nanometers (nm), and so on. International System of Units.

, the standard unit of length is "meter", which is represented by the symbol "m". The length unit adopted in China is consistent with the International System of Units, that is, "meter" is used as the legal unit of length measurement in China.

A kilometer, also known as a kilometer, is a unit of length, abbreviated as "km", and is often used to measure the distance between two places. The common conversion relationship is as follows: 1 km (km) = 1,000 m (m) = 100,000 cm (cm).

1,000,000 mm (mm.)

km = 1 mile.

The commonly used units of length are millimeters (mm), centimeters (cm), decimeters (dm), meters (m) and kilometers (km).

1. Millimeter, also known as millimeter (or meter), is a unit of length and rainfall, the English abbreviation millimeter is equivalent to 1 centimeter, 100 millimeters is equivalent to 1 decimeter, and 1000 millimeters is equivalent to 1 meter (this is the literal meaning of milli).

About the advance rate of millimeters: 1 millimeter = centimeter; 1mm= 000μm=1 000 000nm

2. Centimeter is a unit of measurement for length, which is equal to one hundredth of a meter. The unit of length, abbreviated as cm, 1 cm = 1 100 meters. 1cm (cm) = 10mm (mm) = dm) = m).

The International System of Units (SI) has chosen seven quantities that are independent of each other as the base quantities, the first of which is length. Its base unit name is the meter, the symbol is m, and the centimeter is not an SI unit.

3. Decimetre (English name decimetre, dm) is one of the metric units of length, and 1 decimeter is equivalent to one-tenth of 1 meter. Ten centimeters is equal to one decimeter, and ten centimeters are equal to one meter.

Transform relationships. Kilometers (km) = 1 decimeter (dm).

Meter (m) = 1 decimeter (dm).

10 centimeters (cm) = 1 decimeter (dm).

100 millimeters (mm) = 1 decimeter (dm).

10 decimeters (dm) = 1 meter (m).

Decimeter (dm) = 1 centimeter (cm).

Decimeter (dm) = 1 millimeter (mm).

4. "metre", the basic length unit of the International System of Units, the symbol is m. It can be used to measure length, width, and height. The definition of "rice" originated in France.

The length of 1 meter was originally defined as one ten-thousandth of the distance from the Earth's equator to the North Pole on the meridian through Paris, and was subsequently identified with the International Meter Prototype.

Since 1983, the length of a meter has been defined as "the distance traveled by light in a vacuum in 1 299 792 458 seconds".

5. Kilometers are commonly known as kilometers, and are expressed in English by km (kilometre). In May 1790, a special committee of French scientists recommended that one 40 millionth of the length of the meridian of the earth passing through Paris be used as the unit of length - the meter. 1 km = 1,000 m = 10,000 decimeters = 100,000 cm.

1 km (km) = 1000 m (m) = 1 0000 dm = 10 0000 cm (cm) = 100 0000 mm (mm).

The unit of length refers to the basic unit of measuring the distance in space, and it is the basic unit formulated by human beings in order to standardize the length. Its SI unit is "meter" (symbol "m"), and the commonly used units are millimeters (mm), centimeters (cm), decimeters (dm), kilometers (km), meters (m), micrometers (m), nanometers (nm), and so on. Units of length play an important role in various fields.

Kilometers (km), meters (m), decimeters (dm), centimeters (cm), millimeters (mm), filamental meters (dmm), micrometers (um), nanometers (nm), picometers (pm), light years (ly), astronomical units (au), parsecs (pc).

The units of length are: millimeters (mm), centimeters (cm), decimeters (dm), meters (m), kilometers (km), microns (um), nanometers (nm), silk meters (dmm), and millimeters (ym).

What are the units of length

There are three main types of length units: common units, astronomical units, and special units, and the specific contents are as follows:

1. Commonly used length units.

There are mainly kilometers, decimeters, centimeters, millimeters, micrometers, nanometers, picometers, and femtometers, which are all used in our life fields.

2. Astronomical length unit.

It mainly includes light years, parsecs, astronomical units, lunar distances, earth diameters, terameters, light minutes, light seconds, and Beijing meters, and astronomical units are mostly used to represent the distance between celestial bodies.

3. Special length unit:

The special length units are Eggstrand, Planck length, silk meter, hu meter, femtometer, ami, thousand meters, and unit meter. It is mainly used to represent the length of some relatively small elements, such as atoms.

All units of length in the world.

1 Planck length = 625 t1 m, 1 m1 m = 1 m1 m, 1 thousand m = 10 t1 m, 1 ami = 1 hundredth of a m, 1 femtom = 1 gigabit of a meter, 1 picometer = 1 trillion m, 1 nanometer = 1 billionth of a meter, 1 micron = one millionth of a meter, 1 mm = 1000th of a meter, 1 cm = 1% m, 1 decimeter = 10% m, 1 m, 1 mile = 500 m, 1 km = 1000 m, 1 light second = 299792458 m, 1 terameter = 1 megameter, 1 light year = 9460730472580800 meter.

1 parsec = light year, 1 amy = 105 light years, 1 thousand parsecs = light years, 1 zemi = 10,000 light years, 1 million parsecs = 10,000 light years, 1 Yao meter = 100 million light years, 1 gigaparsec = 100 million light years.
