If it is ANPB, the equivalent should be basically 1:1, since ANPB has nothing in it but peanuts and salt.
Last time I checked, it was exactly like this: 100 grs Peanuts=600cals, 100 grs ANPB= 600 cals.
as for the translation of Tbps of ANPB to handfuls of peanuts, I don't know, you will have to measure them.
