How to convert

1 yard (yd) = 914400 micron (µ). Yard (yd) is a unit of Length used in Standard system. Micron (µ) is a unit of Length used in Metric system.

Yard: A Unit of Length

A yard is a unit of length that is equal to 3 feet or 36 inches in the imperial and U.S. customary systems of measurement. It is also equal to 0.9144 meter in the International System of Units (SI). A distance of 1,760 yards is equal to 1 mile. The symbol for yard is yd.

How to Convert Yard

To convert a yard to other units of length, you can use the following formulas:

  • To convert a yard to feet, multiply by 3. For example, 5 yd = 5 x 3 ft = 15 ft.
  • To convert a yard to inches, multiply by 36. For example, 5 yd = 5 x 36 in = 180 in.
  • To convert a yard to meters, multiply by 0.9144. For example, 5 yd = 5 x 0.9144 m = 4.572 m.
  • To convert a yard to centimeters, multiply by 91.44. For example, 5 yd = 5 x 91.44 cm = 457.2 cm.
  • To convert a yard to millimeters, multiply by 914.4. For example, 5 yd = 5 x 914.4 mm = 4572 mm.
  • To convert a yard to kilometers, divide by 1093.6133. For example, 5 yd = 5 / 1093.6133 km = 0.00457 km.

Where Yard is Used

The yard is mainly used in the United States, the United Kingdom and some other countries that have historical ties with them. It is used for measuring length, distance, area and volume in various contexts such as:

  • Sports: The yard is used for measuring the length of a football field (100 yd), the width of a soccer field (70 yd), the height of a basketball hoop (10 ft or 3.33 yd) and the distance between bases in baseball (90 ft or 30 yd).
  • Textiles: The yard is used for measuring the length of fabrics and yarns (e.g., a yard of cloth, a skein of yarn).
  • Construction: The yard is used for measuring the dimensions of buildings and structures (e.g., a yardstick, a cubic yard of concrete).
  • Transportation: The yard is used for measuring the speed and distance of vehicles (e.g., miles per hour, yards per second).

Definition of the Yard

The current definition of the yard was established by an international agreement in 1959 as exactly 0.9144 meter. This definition was based on a prototype bronze bar that was forged in 1855 as an exact copy of the British Imperial Standard Yard held by Parliament. The prototype bar was called Bronze Yard No.11 and was the official standard of length for the United States until 1892.

The yard is defined as the length of the path travelled by light in vacuum during a time interval of

(1/299792458) × (3600/3937)

seconds. This means that one yard is equal to 3600/3937 light seconds.

History of the Yard

The origin of the yard measure is uncertain. It may have derived from the old English unit of tax assessment called the yardland, which was equal to 1/4 hide or about 30 acres. It may also have derived from the old English unit of surveying called the rod, which was equal to 1/4 chain or about 16 (1/2) feet.

The word “yard” comes from the old English word “gerd” or “gyrd”, which meant a branch, a staff or a measuring rod. The word “yard” was first used to describe this length in William Langland’s poem Piers Plowman in the late 14th century.

The first official standard for the yard was established by King Henry I of England in the early 12th century. He ordered that the yard should be equal to the length of his arm from the tip of his nose to the end of his thumb.

The yard was also used in other countries, such as Scotland, Ireland, France and Spain, with slight variations in length. For example, the Scottish yard was equal to 37 inches, the Irish yard was equal to 40 inches, the French yard was equal to 39.37 inches and the Spanish yard was equal to 32.38 inches.

The yard underwent several changes and refinements over the centuries, until it was finally standardized as 0.9144 meter in 1959 by an international agreement between the United States, the United Kingdom, Canada, Australia, New Zealand and South Africa.

Example Conversions of Yard to Other Units

Here are some example conversions of yard to other units of length:

  • 1 yd = 3 ft
  • 1 yd = 36 in
  • 1 yd = 0.9144 m
  • 1 yd = 91.44 cm
  • 1 yd = 914.4 mm
  • 1 yd = 1/1093.6133 km
The yard is equal to 36 inches or 3 feet.

Micron: A Unit of Length

A micron is a unit of length that is equal to one millionth of a meter. It is also known as a micrometer or a micrometre. The symbol for micron is µm.

How to Convert Micron

To convert micron to other units of length, we need to use some conversion factors. Here are some common conversion factors for US Standard system and SI system:

  • 1 inch = 25,400 µm
  • 1 foot = 304,800 µm
  • 1 mile = 1,609,344,000 µm
  • 1 centimeter = 10,000 µm
  • 1 meter = 1,000,000 µm
  • 1 kilometer = 1,000,000,000 µm

Using these conversion factors, we can multiply or divide the number of microns by the appropriate factor to get the equivalent length in another unit. For example:

  • To convert 50 µm to inches, we divide 50 by 25,400 and get 0.00197 inches.
  • To convert 3 feet to microns, we multiply 3 by 304,800 and get 914,400 µm.

Where Micron is Used

The micron is used in various fields and applications that require measuring very small distances or sizes. Some examples are:

  • In biology and medicine, the micron is used to measure the size of cells, bacteria, viruses, and other microscopic organisms.
  • In engineering and manufacturing, the micron is used to measure the thickness of films, coatings, wires, fibers, and other materials.
  • In astronomy and optics, the micron is used to measure the wavelength of infrared light and the resolution of telescopes and cameras.
  • In geology and mineralogy, the micron is used to measure the grain size of rocks and minerals.
  • In chemistry and physics, the micron is used to measure the diameter of atoms and molecules.

The use of micron varies by country and region. For example:

  • In the United States and Canada, the micron is commonly used in engineering and manufacturing industries.
  • In Europe and Asia, the micron is widely used in science and technology fields.
  • In Australia and New Zealand, the micron is often used in agriculture and forestry sectors.

Definition of the Micron

The micron is defined as one millionth of a meter. A meter is the base unit of length in the SI system. The SI system is an international system of units that is based on seven fundamental quantities: length, mass, time, electric current, temperature, luminous intensity, and amount of substance.

The meter was originally defined as one ten-millionth of the distance from the equator to the North Pole along a meridian. However, this definition was not very precise and practical. Therefore, over time, the definition of the meter has changed several times based on different physical constants and standards. The current definition of the meter was adopted in 1983 by the General Conference on Weights and Measures (CGPM). It states that:

The meter is the length of the path travelled by light in vacuum during a time interval of 1/299792458 second.

Using this definition, we can derive that one micron is equal to:

1 µm = (1/299792458) / (1000000) second * (299792458 m / second)

= (1/1000000) m

= 0.000001 m

History of Micron

The micron was first introduced in the late 18th century by French scientists who were developing a decimal system of units. They proposed a unit called micrometre that was equal to one millionth of a meter. However, this unit was not widely accepted or used at that time.

In the early 19th century, British scientists adopted a similar unit called microinch that was equal to one millionth of an inch. This unit was more popular among English-speaking countries and regions.

In the late 19th century, German scientists proposed a new unit called mikrometer that was also equal to one millionth of a meter. This unit was more consistent with the metric system and became more widely used in Europe and Asia.

In the early 20th century, the International Bureau of Weights and Measures (BIPM) recommended using the term micrometer instead of micron or mikrometer to avoid confusion with other units. However, many people still preferred using micron as a shorter and simpler name.

In 1960, the CGPM adopted the SI system as the official system of units for science and technology. The SI system used the term micrometer as the official name for the unit of length equal to one millionth of a meter. The symbol for micrometer was also standardized as µm.

However, the term micron and its symbol µ were still widely used in many fields and applications. Therefore, in 1975, the CGPM decided to allow the use of micron and µ as alternative names and symbols for micrometer and µm. However, they also stated that these alternatives should be avoided in official documents and publications.

Example Conversions of Micron to Other Units

Here are some examples of converting micron to other units of length:

  • 1 µm = 0.000001 m
  • 1 µm = 0.001 mm
  • 1 µm = 0.00003937 inch
  • 1 µm = 0.000003281 foot
  • 1 µm = 0.000000001 km
  • 1 µm = 0.0000006214 mile
  • 1 µm = 1000 nm
