Isn't it the kinetic energy = 0.5*mv ?  m is small, but v is large and
v squared is very large.  However, the velocity of meteors, v, is a
long way from the speed of light, c.  If meteoroids converted all of
their mass into energy, we'd see some very spectacular fireworks from
even micrometeoroids.   However, I wouldn't want to be too close to a
fireball-sized object doing this. (-:
