If you use a regular grenade launching blank and a dummy (pineapple) grenade on an adapter, it will have roughly 216.233 ft/lbs. of energy.

The grenade with adapter weighs about 22 oz (the grenade itself weighs 500 grams, or 17.6369 ounces).

There are 28.3495231 grams in one ounce.

There are 203 grains in 13 grams.

The approximate velocity of the grenade with adapter from a Yugo SKS with a designated grenade launching blank is 100 F.P.S.

The formula for energy is M x V2 ? 450400 = foot pounds energy, where M= the object's weight in grains.

22 x 28.3495231 ? 13 x 203 x 10,000 (velocity squared) ? 450400= 216.233338257


Neat, huh?
