Consumer fireworks contain a maximum of 1.5 grams of fireworks. I was wondering, in comparison, about how much firepower is this. I know it is a minimal amount.

Most explosives have about 4.6 kJ/gm of thermal energy. So your 1.5 gm has enough heat to raise a quart (or liter) of water 3.3 deg F (1.8 deg C).
In terms of mechanical work, a properly confined explosion, such as a piston in a cylinder, can have a thermodynamic efficiency of 30% so you could launch a 160 lb (73 kg) person 10 feet (3 meters) into the air with that 1.5 grams.
Finally, this is 23 grains of powder, about half the charge in a 22 caliber shell.

If you know what an M-80 is, it is equivalent to an eighth of a stick of dynamite.
