Unit of Distance

In the CGS system, a centimeter is the unit of measurement. Distance is the physical measurement of how far an object has moved in physics. The term "distance" refers to a scalar quantity.

The SI Unit Of Measurement For Distance

According to the International System of Units, a meter is the SI unit of distance. Many other derived units or quantities, such as volume, area, acceleration, and speed, are generated using this as the basic unit and some equations.

Distance Metric Unit

The C.G.S. and M.K.S. unit systems are both used to measure distance in metric units. The metric units of distance are listed in the table below:

Converting Distances

The table below shows how to convert distance between several units of measurement:

Distance Units That Are Frequently Used

Other units are used when we talk about or have to measure longer distances. Among them are the following:

• 7 x 1010 cm is the solar radius.
• The Astronomical Unit (AU) is equal to the mean distance between the Earth and the Sun, which is 1.496 x 1013 cm, or approximately 93 million miles.
• The distance travelled by light in one year, or 9.46 x 1017 cm, is called a light-year (ly). Furthermore, a light-year is equal to 9,500,000,000,000 kilometres.
• The parsec (pc), or 3.1x 1018 cm, is the distance at which an object experiences a parallactic shift of 1 second of arc. In most cases, a pc contains 3.26 ly and 206,265 AU.

Most Commonly Asked Questions

1. What is the largest unit of measurement?
Ans: The parsec is the largest unit of measurement used to determine the distance between celestial objects outside the solar system.

Q2. What is the smallest distance unit?
Ans: Planck length, abbreviated as p, is the lowest unit of distance, equaling 1.616255(18)x10-35.
