What is the relationship between the unit of length C and the millimeter

There's no c in the unit of length, so it definitely doesn't have anything to do with millimeters What I'm wondering is why you want to ask this question. This may help everyone with your questions.

Centimeter is cm mm is mm The relationship between cm and millimeter is too vague.

Yours is in the hardware. That's how machines count. The main thing is 1mm = 100c.

1zm = 1 10 21m (Zemi).

1em = 1 10 18m (Amy).

1 light-year = light-year).

1pm = 1 10 15m (pats)

1tm = 1 10 12m (terami).

1gm = 1 10 9m (Jimmy).

1mm = 1 10 6m (megameters).

1km = 1 10 3m (km).

1hm = 1 10 2m (100 meters).

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

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

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

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

1cmm=1 10 (-5)m

1 m = 1 10 (-6)m (microns).

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

1pm=1 10 (-12)m (picomi).

1fm = 1 10 (-15)m (femtom).

1am = 1 10 (-18)m (ami).

1zm = 1 10 (-21) m (thousand meters).

1ym=1 10 (-24)m

It is possible to denote calories in calories.

A trace is one-half of the ten dust of a flower thread, which belongs to the micro-unit of calculating length, capacity, and weight.

1 mm = 100 filaments (tracts).

Silk is also called, not silk rice in the unit system.

It is customary to call the silk that is humi, 1 silk.

10 microns. 1. Humi Huai Chun.

Silk rice. Millimetre. Centimeter. Rice.

cm is a unit of measurement for length, the centimeter, which is abbreviated as cm.

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. Commonly used units include kilometers (km), meters (m), centimeters (cm), millimeters (mm), decimeters (dm), microns (m), nanometers (nm) and so on.

Units of length play an important role in hand-making in various fields. A unit of measurement is a measure chosen by people to measure a certain type of measurable size, and its value is determined by the definition of that unit. The physical standard that embodies the quantity given by the unit definition and has the highest accuracy is called the measurement benchmark of the unit.

China has a glorious ancient civilization, measurement and testing technology is an important part of this civilization, and as a geometric quantity in metrology, it has a long history of development.

Conversion of units:

Yao m = 1000 Zemi = 10 21 km = 10 24 m 10 8 light years (1ym = 1000zm).

Zemi = 1000 Amy = 10 18 km = 10 21 m 100000 Guangbi Jingyi (1zm = 1000em).

Amy = 1000 patameter = 10 15 km = 10 18 m Light years (1em = 1000pm).

Pat meter = 1000 terameter = 10 12 km = 10 15 m = one trillion km (1pm = 1000tm).

Taimi = 1000 Jingmi = 10 9 km = 10 12 meters (1tm = 1000gm) <>

The unit of length cm, which means centimeter.

cm is the length measurement unit, the Chinese translation is centimeter, 1cm = 10mm (mm), 10cm = 1dm (decimeter), is the most basic length measurement unit, more short round filial piety things, will use cm to measure.

The length of the measurement is carried out by the Wang method:

1. Straightening method.

Use other tools to turn the curve into a straight line and measure it with a scale.

2. Alternate ruler method.

For the measurement of long and curved curves, you can use the round wheel to roll along the curve, record the number of revolutions that the wheel rolls, and then measure the circumference of the wheel, and then multiply the circumference of the wheel by the number of revolutions to obtain the length of the curve.

3. Oblique orthodoxy.

Using geometric knowing, use triangles and rulers to measure things like the height of a cone, the diameter of a cylinder, the diameter of a ball, etc.

4. Accumulation method.

The total length of multiple identical objects with a small length is measured by stacking them together, and then dividing the total length by the number of stacked objects (the number of sheets) to obtain the length of a single object, and the diameter of a thin copper wire and the thickness of a piece of paper can be measured in this way, which can improve the accuracy of measurement. <>

A thread is one-twelfth of a thread and belongs to the micro-unit of calculating length, capacity, and weight.

1 mm = 100 filaments (tracts).

Silk is also called, not silk rice in the unit system.

It is customary to call the silk that is humi, 1 silk.

10 microns. 1 humi.

Silk meter = millimeter.

Centimeter = meter. Origin of the unit of length:

The "meter" (metre), the unit of length of the International System of Units, originated in France. In May 1790, a special committee of French scientists recommended that the length of the earth's meridian passing through Paris be 1/40 millionth of the length of the meter, which was approved by the French parliament in 1791.

In order to create a reference device to characterize the value of the meter, measurements were made in 1792 1799 from Dunkirk, France, to Barcelona, Spain, under the leadership of French astronomers Gerionum and Mishen.

In 1799, a platinum metre bar with a short section of 25 mm was made according to the measurement results, and the distance between the two ends of the pole was set at 1 meter, and it was handed over to the French archives for safekeeping, so it is also called "archive meter".

"C" is the silk meter, and a trace is 1 100 mm.

The unit of silk. It is a thousandth of a point, which is a microunit for calculating length, capacity, and weight, and generally needs to be measured with vernier calipers, micrometers, and smaller block gauges.

It has been determined that the diameter of a hair is about five to seven strands (i.e., a "thread" is a tiny unit).

centimeters, units of length; English: centimetre(s), abbreviated (symbol) is: cm. The unit conversion for centimeters is as follows: 1 centimeter = 10 millimeters = decimeters = meters = kilometers.

The millimeter, also known as the millimeter (or gong), is a unit of length and a unit of rainfall, symbol. 1 millimeter is equivalent to 1/1000th of a meter (this is the literal meaning of "milli"). The base system relationship is as follows: 1 mm = cm = decimeter = meter = kilometer.

A micron is a unit of length, the symbol [micron], pronounced [miú]. 1 micron is equivalent to one millionth of a meter (this is the literal meaning of "micro").

Thickness: This is only used in some professions, such as paper thickness, etc.

1c (filament) = mm.

The length you said didn't.

Amount of electric charge: Ku "Lun", c (other expressions: a·s).

Frequency: Weeks (equivalent to Hertz, "week" is not legal) c, 1 Hz = 1 week.
