That depends on a lot more than the weight of the explosive.
The type of explosive
How it's packed
The material being fragmented
The shape of the fragments
To give you an illustration, a Mark II grenade (the "pineapple" one) has an effective injury radius of about 10 meters, but someone could still be injured by one 100 meters away.
If the projectiles are small enough, they can travel around the world from a 1-pound explosion.
Half a Mile
Tiny fragments can travel all the way around the earth from a 1-pound explosion.
they travel how far they want to
Fragments from a 1-pound explosion can potentially travel up to hundreds of feet, depending on factors such as the type of explosive used, the environment, and the presence of barriers. The size and weight of the fragments will also affect how far they can travel.
Depending on the material, it will be 1/2 mile CBRNE - 1/2 mile
Fragments from a 1-pound bomb can travel upwards of 300 feet, but factors such as the type of explosive, environment, and obstacles can impact the distance. The fragments can cause significant damage and injuries within this radius.

Density. The mass of a pound of any two materials on Earth is always the same. However, a pound of steel has far less volume for a pound than a pound of feathers. Thus, steel is far, far denser than feathers are.
