Speed is the rate at which an object moves, while velocity is speed with a specified direction. It is measured in meters per second (m/s).
1 ly/yr = 1,000 mm/s
1 mm/s = 0.001 ly/yr
Example:
Convert 15 Light Year per Year to Millimeter per Second:
15 ly/yr = 15,000 mm/s
| Light Year per Year | Millimeter per Second |
|---|---|
| 0.01 ly/yr | 10 mm/s |
| 0.1 ly/yr | 100 mm/s |
| 1 ly/yr | 1,000 mm/s |
| 2 ly/yr | 2,000 mm/s |
| 3 ly/yr | 3,000 mm/s |
| 5 ly/yr | 5,000 mm/s |
| 10 ly/yr | 10,000 mm/s |
| 20 ly/yr | 20,000 mm/s |
| 30 ly/yr | 30,000 mm/s |
| 40 ly/yr | 40,000 mm/s |
| 50 ly/yr | 50,000 mm/s |
| 60 ly/yr | 60,000 mm/s |
| 70 ly/yr | 70,000 mm/s |
| 80 ly/yr | 80,000 mm/s |
| 90 ly/yr | 90,000 mm/s |
| 100 ly/yr | 100,000 mm/s |
| 250 ly/yr | 250,000 mm/s |
| 500 ly/yr | 500,000 mm/s |
| 750 ly/yr | 750,000 mm/s |
| 1000 ly/yr | 1,000,000 mm/s |
| 10000 ly/yr | 10,000,000 mm/s |
| 100000 ly/yr | 100,000,000 mm/s |
