## How to convert

1 yard (yd) = 9.66542E-17 lightyear (ly). Yard (yd) is a unit of Length used in Standard system. Lightyear (ly) 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.
The yard is equal to 36 inches or 3 feet.

## Lightyear: A Unit of Length

The lightyear is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46 × 10^12 km), or 5.88 trillion miles (5.88 × 10^12 mi). As defined by the International Astronomical Union (IAU), a lightyear is the distance that light travels in a vacuum in one Julian year (365.25 days). The lightyear is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist contexts and popular science publications.

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

## Example Conversions of Lightyear to Other Units

The lightyear can be converted to other units of length by using different factors and formulas. Here are some examples of conversion for different types of units:

• To convert a lightyear to kilometers, multiply by 9.46 × 10^12:

1 ly × 9.46 × 10^12 = 9.46 × 10^12 km

• To convert a lightyear to miles, multiply by 5.88 × 10^12:

1 ly × 5.88 × 10^12 = 5.88 × 10^12 mi

• To convert a lightyear to AU, multiply by 63,241:

1 ly × 63,241 = 63,241 AU

• To convert a lightyear to parsecs, divide by 3.26:

1 ly / 3.26 = 0.31 pc

• To convert a kilometer to lightyears, divide by 9.46 × 10^12:

1 km / 9.46 × 10^12 = 1.06 × 10^-13 ly

• To convert a mile to lightyears, divide by 5.88 × 10^12:

1 mi / 5.88 × 10^12 = 1.70 × 10^-13 ly

• To convert an AU to lightyears, divide by 63,241:

1 AU / 63,241 = 1.58 × 10^-5 ly

• To convert a parsec to lightyears, multiply by 3.26:

1 pc × 3.26 = 3.26 ly
