Convert Earth's equatorial radius to light year
Please provide values below to convert Earth's equatorial radius [R_e] to light year [ly], or Convert light year to Earth's equatorial radius.
1 R_e = 6.7417e-10 ly. To convert Earth's equatorial radius to light year, multiply the value by 6.7417e-10; to go the other way, divide by it (1 ly = 1483306249.55 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
Frequently Asked Questions
What is 1 Earth's equatorial radius in light year?
1 Earth's equatorial radius (R_e) = 6.7417e-10 light year (ly).
How do you convert Earth's equatorial radius to light year?
