A monster's carrying capacity is calculated based on its weight or size relative to a human.[1]
Weighty monsters
If the monster has non-zero weight, its carrying capacity is
.
The weight of a human is 1450 for this calculation.[2] If a strong monster would have less than 1000 carrying capacity based on this calculation, then its carrying capacity is set to 1000.
This can be simplified to 
if the monster is not strong, and 
if the monster is strong.
Weightless monsters
If the monster has zero weight, its carrying capacity is
.
The numerical value used for monster size is that used for physical size: 0 for tiny, 1 for small, 2 for medium, 3 for large, 4 for huge, and 7 for gigantic. Humans have medium (2) size.[3]
Notes
Note that despite the source code comment mentioning corpseless monsters, the formula based on monster size is only used for monsters with a weight of 0. Thus, a corpseless lich, with medium (2) size and 1200 weight, has a carrying capacity of 413, not 500. A wraith, with medium size and 0 weight, has a carrying capacity of 500.
