Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
Inch (in). The inch is an imperial and US customary unit equal to exactly 25.4 millimeters, used for screen sizes, pipes and tyres.
There are 3.7247 × 10¹⁷ inches in one light year.
Multiply the number of light years by 3.7247 × 10¹⁷. For example, 10 light years equal 3.7247 × 10¹⁸ inches.
One inch equals 2.68478 × 10⁻¹⁸ light years.
4.46964 × 10¹⁸ inches. Other common values: 5 light years = 1.86235 × 10¹⁸ inches and 100 light years = 3.7247 × 10¹⁹ inches.
