How to convert

1 lightyear (ly) = 9.46053E+15 meter (m). Lightyear (ly) is a unit of Length used in Metric system. Meter (m) 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

Meter - Unit of Distance / Length

Unit Symbol / Abbreviation: m

Where the unit used in the World:

The meter is used as a unit to measure medium distances or lengths.
It's a standard measure for short distances (up to 1 km long), in real estate and construction, supply materials, vehicle and aircraft dimensions, short geographical distances and directions in most countries excluding the USA where foot and yard are still widely used for this purpose.
The meter is widely used in most countries and is the official unit for medium lengths and distances (for example, road signs in continental Europe show maximum vehicle hight in meters). Primary exceptions are the United States of America, and some countries where feet and yards are used in limited extent: the United Kingdom and Canada, where the yard remains in limited use as a part of imperial system (for example, yards are used on road signs for shorter distances in the United Kingdom and feet are widely used in construction and real estate in Canada).

Definition of the Unit:

The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).

1 m is equivalent to 3.28084 ft or 0.000621371 miles.

Equivalents in other units and scales:

  • 1 m = 1000 millimeters (mm)
  • 1 m = 100 centimeters (cm)
  • 1 m = 10 decimeters (dm)
  • 1 m = 0.001 kilometers (km)
  • 1 m = 3.28084 feet (ft)
  • 1 megameter = 1000000 m
  • 1 gigameter = 1000000000 m
  • Units of length in the metric SI system are based on multiples or fractions of a meter.
  • There are measurements of length/distance in the metric SI system greater than a meter that can be expressed in terms of metres.

1 m is equivalent to 3.28084 ft or 1.09361 yd.

The meter is a unit of length in the metric SI system and is equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).

Meters also can be marked as metres (in British English spelling).
