Light year (ly). A light year is the distance light travels in one year, about 9.46 trillion kilometers.
Meter (m). The meter is the SI base unit of length, defined by the distance light travels in a vacuum in 1/299,792,458 of a second.
There are 9.46073 × 10¹⁵ meters in one light year.
Multiply the number of light years by 9.46073 × 10¹⁵. For example, 10 light years equal 9.46073 × 10¹⁶ meters.
One meter equals 1.057 × 10⁻¹⁶ light years.
1.13529 × 10¹⁷ meters. Other common values: 5 light years = 4.73037 × 10¹⁶ meters and 100 light years = 9.46073 × 10¹⁷ meters.
