What is the velocity of light in vacuum?

It is the constant speed at which electromagnetic waves travel in empty space, defined exactly as 299,792,458 metres per second.

What does cosmic velocity - second represent?

It is the minimum speed needed for an object to escape a celestial body's gravitational field without further propulsion.

Can I use this conversion for all celestial bodies?

No, the conversion uses a fixed ratio and does not account for differences in escape velocities across various bodies.
