## How to convert

1 yard (yd) = 36000000 microinch (µin). Yard (yd) is a unit of Length used in Standard system. Microinch (µin) is a unit of Length used in Standard 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.

## Microinch: A Unit of Length

The microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is a non-SI unit of measurement that is mainly used in engineering and manufacturing fields. The symbol for microinch is µin or µ". The microinch is also a derived unit in the British imperial and US customary systems of measurement.

The microinch is most commonly used when expressing small distances or dimensions, such as the surface roughness or flatness of materials and parts. The microinch is also used for measuring the wavelength of light and other electromagnetic waves.

In this article, we will explore the definition, history, usage and conversion of the microinch as a unit of length.

## Definition of the Microinch

The microinch is a unit of length that is equal to one millionth of an inch (0.000001 inch). It is defined as 25.4 nanometers or 2.54 × 10^-8 meters by international agreement in 1959. One inch is equal to 25.4 millimeters or 0.0254 meter.

The definition of the microinch has changed over time, as different standards and methods of measurement were developed by various countries and organizations. The current definition of the microinch as based on the meter was agreed upon by an international treaty in 1959.

## History of the Microinch

The origin of the microinch as a unit of length can be traced back to the early 20th century, when it was introduced by the American Society for Testing and Materials (ASTM) as a standard for measuring surface roughness. Surface roughness is a measure of how smooth or irregular a surface is, which affects its friction, wear and corrosion properties.

The microinch was adopted by other countries and industries that followed the American system of measurement, such as Canada and Japan. It was also incorporated into the ANSI/ASME B46.1 standard for surface texture in 1985.

The microinch was also used by some optical scientists and engineers to measure the wavelength of light and other electromagnetic waves. For example, the visible spectrum of light ranges from about 4,000 to 7,000 microinches.

## Usage of the Microinch

The microinch is a unit of length that is used for measuring small distances or dimensions, such as the surface roughness or flatness of materials and parts. For example:

• Measuring the smoothness or roughness of metal surfaces, such as steel, aluminum and copper.
• Measuring the flatness or curvature of glass surfaces, such as lenses, mirrors and windows.
• Measuring the thickness or diameter of thin films, coatings and wires.
• Measuring the accuracy or tolerance of machined parts, such as gears, bearings and shafts.

The microinch is commonly used in engineering and manufacturing fields, especially in precision machining, metrology and quality control. Some examples are:

• Measuring the surface finish of machined parts, such as turned, milled and ground surfaces.
• Measuring the surface profile of textured surfaces, such as honed, lapped and polished surfaces.
• Measuring the surface geometry of complex surfaces, such as grooved, fluted and serrated surfaces.
• Measuring the surface defects of defective surfaces, such as scratches, pits and dents.

The microinch is also used for measuring the wavelength of light and other electromagnetic waves. For example:

• Measuring the color or frequency of visible light, infrared light and ultraviolet light.
• Measuring the polarization or phase of coherent light, such as laser light and holographic light.
• Measuring the interference or diffraction patterns of interfering light, such as interferometric light and diffractive light.
