(Damage Per Second)
Roughly translates to a weapons "True" damage capacity. High DPS weapons can kill immediately, where low DPS weapons may have to land multiple hits before doing any worthwhile damage. To find the true value of this, one would have to find out how many rounds can be fired within a second, and then multiply the answer by the weapon's damage. A more practical "approximate value" can roughly be calculated using (Damage) * (RoF), but this is not always true since RoF has more influence on DPS than damage, so use it as a reference number only. In both calculations there are other factors which affect DPS, such as penetration, Range, and the use of a silencer.
