How to convert

1 lightyear (ly) = 9.46053E+16 decimeter (dm). Lightyear (ly) is a unit of Length used in Metric system. Decimeter (dm) is a unit of Length used in Metric system.

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

Decimeter: A Unit of Length

The decimeter (dm) is a unit of length in the metric system, which is the most widely used system of measurement in the world. The decimeter is equal to one tenth of a meter, which is the SI base unit of length. The decimeter is also a derived unit in the International System of Units (SI), which is the official system of measurement for science and engineering. The symbol for decimeter is dm. The decimeter is used for measuring medium distances and dimensions, such as the height of a bookshelf or the width of a door. The decimeter is also used for measuring volumes, such as the volume of a cube or a box. The decimeter is named after the deci prefix, which means one tenth in Latin. In this article, we will explore the definition, history, usage and conversion of the decimeter as a unit of length.

How to Convert Decimeter

The decimeter can be converted to other units of length by using conversion factors or formulas. Here are some examples of how to convert decimeters to other units of length in the SI system, the US customary system and other systems:

• To convert decimeters to centimeters, multiply by 10. For example, 10 dm = 10 × 10 = 100 cm.
• To convert decimeters to meters, divide by 10. For example, 10 dm = 10 / 10 = 1 m.
• To convert decimeters to kilometers, divide by 10000. For example, 10 dm = 10 / 10000 = 0.001 km.
• To convert decimeters to inches, multiply by 3.937. For example, 10 dm = 10 × 3.937 = 39.37 in.
• To convert decimeters to feet, multiply by 0.328. For example, 10 dm = 10 × 0.328 = 3.28 ft.
