![]() Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. Note that rounding errors may occur, so always check the results. 1 metre is equal to 1.0577248071986E-25 gigalight-year, or 3.2407792700054E-23 megaparsec. One Megaparsec is equal to 3261563.8 Light Years and that means we can also write it as 1 Megaparsec 3261563.8 Light Years, feel free to use our online. You can find metric conversion tables for SI units, as well as English units, currency, and other data. You can view more details on each measurement unit: gigalight-year or megaparsec The SI base unit for length is the metre. More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely far away from any gravitational or magnetic fields, in one Julian year (365.25 days of 86400 seconds each).Ĭ provides an online conversion calculator for all types of measurement units. It stands for "parallax of one arc second", and is approximately 19,131,554,073,600 (19 trillion) miles.Ī light year, abbreviated ly, is the distance light travels in one year: roughly 9.46 × 1012 kilometres (9.46 petametres, or about 5.88 × 1012 (nearly six trillion) miles). This distance is referred to as one light year. ![]() As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). The parsec (symbol pc) is a unit of length used in astronomy. In one Earth year of 364.25 days (8,766 hours), light travels a distance of 5,878,625,370,000 miles (9.5 trillion km). A light-year, alternatively spelled light year, is a 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). We assume you are converting between megaparsec and light year.You can view more details on each measurement unit: Mpc or light-year The SI base unit for length is the metre. The definition of a parsec is as follows: More information from the unit converter. The SI prefix "mega" represents a factor of It is said that one parsec is equal to about 3.3 light years. Light years to megaparsecs, or enter any two units below: Enter two units to convert From: Just like the parsec (an abbreviation for Parallax of one arcsecond) and kiloparsec (equivalent to 1,000 parsecs, or KPC for short), the megaparsec (or MPC) is a measurement unit that is used in astronomy to measure the great, vast distance between galaxies in intergalactic space. You can do the reverse unit conversion from
