Actually, my understanding is that 'suitcase' nukes are generally under 0.1 kT, and they are still a lot bigger than suitcases - 50 kg is a pretty good weight estimate. At any rate, there is no straight conversion from weight to explosive force - the smaller the bomb gets, the less efficient it becomes.
Also, as I said before, a really small bomb won't produce an explosion at all. If you could build a microgram nuke (which you can't), it would simply produce a sharp burst of radiation (mostly x-rays). If it goes off in your ear, most of the energy will pass right through you and be absorbed by the surrounding building, ground, air, etc. It might cause radiation sickness, but with even primitive medical nanotech it takes an awful lot of radiation to kill people.
