Light years 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.

The unit meter, also known as the ym in English, is recognized as the smallest unit of length.
1 meter is 1ym 10 24m 1 0570x10 40 light years and meters.
1 m 10 (24)m;
1 meter light year;
1 meter of rice;
1 meter Planck length;
1 meter 1 100 megananometers.
1 meter = 1,100 trillion trillion kilometresThe smallest unit of length in the world: the millimeter is not visible to a microscope, and the minimum limit of resolution for optical microscopes is up to microns (1 million microns = = 1 meter) and the minimum limit for resolution for electron microscopes is up to picometers (1 trillion picometers = = 1 meter).

No thanks, I wish you a great day.
The largest unit of length in the world is the yaomi, which is symbolized as ym.
Presentation of the length.
1. Definitions. 1. Length is a measure of one-dimensional space, which is the distance from point to point. Typically, when measuring the length of a line segment in 2D space, the longer is called the longer with the larger length value, not larger than its value, or the width at the "side". So width is actually a measure of length, so the height of the "vertical length" measured in three-dimensional space is the length.
Length is one of the seven dimensions of the fundamental physical quantities in the International System of Units (SI) with the symbol L.
2. Unit conversion.
1 km = 1 km.
1 km 1000 m.
1 meter 10 dm.
1 dm 10 cm.
1 cm 10 mm.
1 mm 1000 μm.
3. Measurement. 1. Measurement of length.
The measurement of length is the most basic measurement, and the most commonly used tool is a scale. The SI unit of length is the meter (m), and the commonly used units are kilometers (km), decimeters (dm), centimeters (cm), millimeters (mm), microns (m), nanometers (nm), etc.
When converting the units of length, multiply small units to large units, and divide large units to small units.
2. Correctly use the scale scale, scale, and graduation value.
2) Pay attention when using:
The ruler should be placed along the measured length, and the edge of the ruler should be aligned with the measured object, which must be placed in a positive and overlapping manner, and should not be skewed.
Do not use worn zero tick marks, such as taking another whole tick mark as a zero tick due to the wear of the zero tick, do not forget to subtract the tick value of the replaced zero tick from the last reading.
A thick ruler should be placed vertically.
When reading, the line of sight should be perpendicular to the ulnar surface.
3. Record the measured values correctly.
Measurements are made up of numbers and units.
1) Records that only write numbers without units are meaningless.
2) When reading, it is necessary to estimate the scale index.
The difference between the measured value and the true value.
Errors cannot be avoided and can be minimized, and errors should not be avoided.
The basic method of reducing the error: the average value of multiple measurements, in addition, the selection of precision instruments, and the improvement of the measurement method can also reduce the error.
4. Special method measurement.
1) Accumulation method (turning less into more).
For example, measuring the diameter of a thin metal wire or measuring the thickness of a piece of paper.
2) Caliper method.
4) Auxiliary method (making it easy to make it easy), such as measuring the diameter of a table tennis ball.
5) Cotton thread method (turning curves into straights) is such as measuring the length of a curve on a map.
6) Roller method (making it easy), such as measuring the perimeter of the playground runway.

1 meter (m) = 100 centimeters (cm);
1 centimeter (cm) = 10-2m
10 millimeters (mm);
1 millimeter (mm) = 10-3m
1000 microns (um);
1 micron (um) = 10-6m = 1000 nanometers (nm);
1 nm = 10-9m. [The size of the virus is about 100 nanometers] nanometers (nm) = between [-7 of 10 and -9 meters of 10] = fineness and size, which is converted into about 180,000 meshes and 18 million meshes.
Micron (um) = [10 to the 6th power or less] = fineness, the size of the mesh is converted to about 10,000 mesh or less. The ultimate fineness of microns is 18,000 mesh.

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.
At present, the units of length established are: Yao Meter (YM), Ze Meter (ZM), Amy (EM), Light Year (LY), Peameter (PM), Terameter (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), Micrometer (M), Nanometer (NM), Picometer (PM), Femtometer (FM), Ami (AM), Millimeters (zm), millimeters (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.
A 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.
Yaomi is also unknown 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.
