A parsec is ameasure of distance 1 parsec is equal to 1.9174x10 to the 13th power- miles 3.08568 x 10 to the 13th power-kilometers Answer 1 Parsec = 3.08568025 × 1016 meters
1 Parsec = 3.26156 light years
The parsec ("parallax of one arcsecond", symbol pc) is defined as the length of the adjacent side of an imaginary right triangle in space. The two dimensions that form this triangle are the parallax angle (defined as 1 arcsecond) and the opposite side (which is defined as 1 astronomical unit (AU), the distance from the Earth to the Sun).
Given these two measurements, along with the rules of trigonometry, the length of the adjacent side (the parsec) can be found.

∙ 15y agoThe light year is the distance light can travel in 1 Earth year.
The parsec is derived from a method by which distances to nearby stars can be measured. As the Earth orbits around the sun, the position of nearby stars changes very slightly relative to much more distant stars. you can try this idea with whatever is at hand, pick two objects that are both in your line of sight but different distances away, keep your eyes on them, and move your head from side to side. their positions in your "sky" change. this is called parallax.
if the more distant star is far enough away that it is essentially fixed in the sky, then the angle of parallax can be used to calculate the distance to the nearby star. 1 parsec corresponds to the distance a star would be at to exhibit a parallax of 1 arcsecond (which is 1/3600 of a degree)
1 parsec = 3.26 light years.

∙ 14y ago1 parsec (about 19 trillion miles, or 3e+16 kilometers) is approximately 3.26156377697121 light years.
Andromeda, our closest neighboring galaxy, is about 2.5 million light years away, or around 766,503 parsecs!

∙ 11y agoA light-year is the distance that light travels in one year. Light travels at 186,000 miles per second, or about 300,000 kilometers per second.
There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days per year.
One parsec is the distance away from Earth that an object would be if the apparent parallax (the apparent visual shift as compared to the very distant stars) is one second of arc when viewed from the Earth at opposite sides of its orbit around the Sun. That is, the length of the sides of an isosceles triangle whose base is 186,000,000 miles and which has a vertex angle of one second of arc. (There are 60 seconds in a minute, 60 minutes of arc in one degree, and 360 degrees in a circle. So one second of arc is 1/3600th of a degree.) "Parsec" is an abbreviation for "one PARallax SECond of arc", and is approximately equal to 3.26 light years.

What is the three convenient unit to measure range from very small length to very long length?
Nanometre, centimetre and parsec are three possible answers.
Which unit represents the largests unit of length?
The official unit for length is the meter. The kilometer (1000 meters) is often used in practice. Larger distances/lengths are often expressed in meters or kilometers; if the numbers are very large, scientific notation is used. On the other hand, in astronomy the following non-SI units are often used for very large distances:The astronomical unit, which is the average distance from Sun to Earth. Approximately 150 million km.The light-year, the distance light travels in a year. Approximately 9.5 x 1012 km.The parsec - a hypothetical star at that distance would have a parallax of 1 arc-second (all stars except the Sun are at a distance of more than 1 parsec). 1 parsec is approximately 3.26 light-years. Prefixes such as kilo- and mega- are sometimes used with parsec.
What unit measures things in space?
The largest commonly used in astronomy unit of length is the parsec, equivalent of 206260 astronomical units or 3.26 light years.
Which unit of measurement would you use to measure the perimeter of a room?
Perimeter is a length or a distance, just like depth, height, and circumference are. Any unit of length can be used to describe a perimeter. Some good ones are ... - nanometer - inch - kilometer - parsec - furlong - yard - league - mile - light-year.
Light years are used to measure distance between stars because?
. . they are a convenient unit. Another convenient unit is the parsec.
What is the order of increasing length of astronomical unit parsec kilometer and light year?
kilometer, AU (astronomical unit), light year, parsec.
What is the highest unit for measuring length?
light year * * * * * A parsec, which is approx 3.26 light years, is bigger.
What is the nonstandard unit for length?
The standard unit of length is the meter, and any multiple and submultiple such as kilometer and millimeter. Nonstandard units include foot, inch, mile, light-year, parsec, astronomical unit.
What is the unit of length that measures how far an object is in the outer space?
The usual units of measure are; Astronomical Unit (AU) Light year Parsec
What is the three convenient unit to measure range from very small length to very long length?
Nanometre, centimetre and parsec are three possible answers.
What are parsecs in spore?
The parsec ("parallax of one arcsecond", symbol pc) is a unit of length, equal to just over 30 trillion kilometres, or about 3.26 light years. The parsec is used in astronomy.
What unit measures the size of your galaxy?
The SI (metric) unit for length, of course, is the meter. But for distances at that scale, the non-SI units light-year and parsec are often used instead.
Is parsec a linear distance measure?
Yes. The parsec is a unit of distance, or length, equal to about 3.26 light-years, or 3.09 x 1016 meters.

What is a Long unit of measure for great distances?
The parsec is 3.26 light years. Astronomers measure distances to remote galaxies in megaparsecs--millions of parsecs. This is about the longest commonly used length metric.
What is a light parsec?
"Light-year" and "parsec" are two units of length used in Astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year.
