You see, I haven't played Warhammer and know practically nothing about it, but I'm a bit bored:

On that planet, there were a total of 4,92*10^91 guardsmen. That is a fuckton.

I have no clue how much the average guardsman weighs and I didn't bother to read through hundreds of pages on the Warhammer-Wiki, but I read that a lasgun weighs about 2,3 kg. On pretty much all pics of these guys that I found, the guardsmen only wore "normal" clothing, a chestplate with some armour on the shoulders and a helmet.

They were no bulking masses of genetically engineered supersoldiers that eat for breakfast what Mr. Wealthy Pianoman eats for a week either, so I'm just gonna assume that your average guardsman is a pretty normal dude who is in a rather /fit shape and wears a bit of armour, which makes me put their weight at 100kg.

4,92*10^91 guardsmen with a weight of 100kg each gives these guys a total weight of 4,92*10^93 kg.

Some findings suggest that the mass of "S5 0014+81" is overestimated, but if the calculations are correct, it is the most massive black hole known to man. On wikipedia, its weight is listed as that of 40 billion suns, or, in other words, 4*10^10 suns.

The sun has a mass of about 2*10^30 kg, so S5 0014+81 weighs about 8*10^40 kg.

Thus, the guardsmen on Schindelgheist IV weigh as much as 6,15*10^52 "S5 0014+81"s would.

Depending on which source you look at, there are about 10^22 stars in the universe.

Take as many identical universes as there are stars in our universe, give all stars a planet and put 615 million people on every planet and imagine that everyone of these guys weighs as much as the most massive black hole known to man.

THAT is the mass of these guardsmen.

yeah, it's from the tv show heroes
