True, but there are some analogies between digital pixels and film grains. Both are tiny fragments of a space that get exposed to light during taking a picture. One of the things that makes the comparison difficult is the irregular (by definition) nature of the film grain.

According to Wikipedia the number of MP is slightly lower - 14MP (http://en.wikipedia.org/wiki/Digital_versus_film_photography), but again there are estimations.
