# Meters to light-years

**1 meter in light-years: 1 m = 1.057 × 10^-16 ly**

ly = m × 1.057000834 × 10^-16

To convert meters to light-years, multiply by 1.057000834 × 10^-16. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is ly = m × 1.057000834 × 10^-16. Both units measure length, so the conversion is a fixed factor that never changes.

## Common questions

### How many light-years are in one meter?

One meter equals 1.057 × 10^-16 light-years. ly = m × 1.057000834 × 10^-16.

### How do you convert meters to light-years?

Use ly = m × 1.057000834 × 10^-16. So 10 m is 1.057 × 10^-15 ly.

### How many meters are in one light-year?

One light-year equals 9.4607305 × 10^15 meters, which is the reverse of the conversion above.
