How fast is shrapnel?

Could you elaborate on the velocity of shrapnel? Is it measured in terms of meters per second, or perhaps there's a more specific metric tailored to the nature of shrapnel's explosive dispersion? Is there a range of speeds that shrapnel fragments can reach, depending on the type of explosive or the distance from the blast? Additionally, how does the speed of shrapnel compare to other forms of projectiles, such as bullets or artillery shells?
