Which is the largest of all length units

The largest unit of length is a light-year, which is the distance traveled in a year of light.

With the continuous expansion of human understanding of the macrocosm, the understanding of the microcosm is also deepening. The big units are getting bigger and bigger, and the small units are getting smaller. The largest unit of length commonly used in astronomy is light year, which is the distance traveled by light (kilometers per second) in a year (365 days); The smallest unit of length is "angstroms", one hundredth (10 -8) centimeter.

Later, a smaller unit of length than angstroms, the atto-meter, appearedOne atto-meter is 16th (10-16) centimeters of ten. Since 1960, the shortest unit of measurement of time is called nano-second, which is one billionth of a second.

The light can only travel 30 centimeters in one nano-second.

There are also single fors that are light-years larger. The Sun orbits around the Milky Way, often referred to as a cosmic year, which is equivalent to about 250 million years. However, the largest unit of length is the "kabbal" in the Hindu chronology

One cabal is equal to 4,320 million years, or 19 cosmic years.

The largest unit of length is the Yao meter.

Generally speaking, the length of one light-year is equal to 9,460 kilometers, but one Yao-meter is equal to 100 million light-years, which is equivalent to 100 million billions of meters. 1 Yao meter = 100 million light years = 1 10 24 meters = 100 million billion billion meters = 10 billion billion billion centimeters.

Units of length

It refers to the basic unit of measuring spatial distance, which 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.

When measuring the length of a line segment, it is necessary to select a certain line segment as the measurement standard, and specify its length as 1, and call this line segment a length unit. There are many units of pure dress-up length, the main unit is meters, and the rest are derived units. When measuring, choose the appropriate length unit according to the actual needs.

For example, the length of the runway is measured in meters, the distance between two cities is measured in kilometers, and the distance of the long jump is measured in centimeters. In the International System of Units, the standard unit of length is the meter, which is denoted by the symbol "m". The length unit used in China is consistent with the International System of Units, that is, "meter" is used as the legal unit of length measurement in China.

Light years, kilometers, meters, decimeters, centimeters, millimeters, nanometers, picometers, femtometers.

What are the commonly used units of length.

Vertical and vertical screens. From the Science Education Certification Team 2018-09-23The commonly used length units are millimeters (mm), centimeters (cm), decimeters (dm), kilometers (km), meters (m), microns (m), nanometers (nm) and so on. Units of length play an important role in various fields.

Conversion relationship: 1km (km) = 1 10 3m

1dm (decimeter) = 1 10 (-1) m

1cm (cm) = 1 10 (-2) m

1mm (mm) = 1 10 (-3) m

1dmm (silk meter) = 1 10 (-4) m

1cmm (m) = 1 10 (-5) m

1 m (micron) = 1 10 (-6) m

1nm (nm) = 1 10 (-9)m

Extended Information: Chinese Units:

The traditional Chinese units of length include li, zhang, ruler, inch, xun, yi, fu, yi, step, step, chang, arrow, feast, several, rail, pheasant, milli, centi, minute, etc. The basic conversion relationship is as follows:

1 zhang = 10 feet; 1 foot = 10 inches; 1 inch = 10 points; 1 point = 10 cents;

1 zhang meter; 1 ft decimeter; 1 inch cm;

1 kilometer (km) = 1000 meters; 1 meter (m) = 100 cm; 1 centimeter (cm) = 10 mm.

The largest unit of length: Yao meter (ym).1 Yao m = 1 Yao m = 100 million light years = 1 10 24 m = 100 million billion billion m = 10 billion billion billion billion centimeters.

Yottametre (symbol ym) is a unit of length. 1 ym = 10 24 meters.

The smallest unit of length: the meterThe English symbol ym, also known as yem, is currently the smallest unit of length.

1 meter is 1ym = 10 (-24) m1 meter = light year, 1 meter is equal to 1000 meters.

Length units are arranged from largest to smallest:

Yao Meter (YM), Zemi (ZM), Amy (EM), Light Year (LY), Pat Meter (PM), Tai Meter (TM), Jing Meter (GM), Megameter (mm) Kilometer (km), 100 Meters (HM), Ten Meters (DAM), Meter (M), Decimeter (DM), Centimeter (CM) Millimeter (mm), Silk Meter (DMM), Woo Meter (CM), Micrometer (M), Nano (Nm), Picometer (PM), Femtomi (FM), Ami (AM), Thousand Meters (ZM), Millimeter (ym).

1. The largest unit of length in the world is the Yao meter. Many people know that a light-year is a unit of length, and one light-year is equal to 9,460 kilometers, but few people know that Yaomi is much larger than a light-year.

2. At present, the length units are: Yao Meter (YM), Ze Meter (ZM), Amy (EM), Light Year (LY), Beat Meter (PM), Tai Meter (TM), Beijing Meter (GM), Megameter (mm) Kilometer (km), 100 Meters (HM), Ten Meters (Dam), Meter (M), Decimeter (DM) Centimeter (CM) Millimeter (mm), Silk Meter (DM), Meter (CM), Micron (M), Nano (nm), Picometer (PM), Femtomi (FM), Ami (AM) , Millimeter (zm), Millimeter (ym). Yao meter is the largest unit of these, 1 Yao meter = 100 million light years = = 1 10 24 meters = 1 10 26 cm = 1 10 33 nanometers.

3. The unit of length is a symbol set to measure the distance in space. China follows the International System of Units and adopts the "meter" as the most legal unit of measurement. There are common units, astronomical units, and special units of length.

For example, the light year is a common unit in astronomy, while the yaomi is a rare unit.

4. Yaomi is not known because of its impracticality. It is neither like the "meter" is a legal unit of measurement, nor is it like the light year that is the darling of astronomers. Its sheer amount makes it very small.

The largest unit of length is a light year, which means the distance traveled by light in a year, you can roughly estimate it, the speed of light is 300,000 kilometers per second, the distance of an hour is 3600 times 300,000 kilometers, a day is 24 hours, and each natural year is 365 days. Hope to adopt, thank you.

Yaomi. A light-year is 9,650,000 meters, but one meter is several times more than a light-year. Hope it helps, thank you!

The largest unit of length is the xero meter.
