Scaling determines how much additional damage a weapon deals.
The additional damage is based on the weapon's stat bonus, base damage and your strength, dexterity, faith and intelligence stats.
The weapon's stat bonus is indicated by a letter grade of S/A/B/C/D/E or as - which means no scaling for that stat.
Calculating bonus damage
Each weapon has a base bonus value for each stat, for example the Butcher Knife has a strength bonus of 104
This bonus gets multiplied by a scalar value dependent on the upgrade level. For any weapon maximally upgraded this scalar value is 1.4.
The result of this multiplication is divided by 100 and then multiplied by a value dependent on your strength stat. This gets multiplied by the weapon damage.
This calculation is done for every stat the weapon has a bonus for and then these values get added together to form the bonus damage.
My character uses a Butcher Knife+10 with a strength bonus of 104 and 190 weapon damage.
It is a +10 weapon so the scalar value is 1.4.
My character has 25 strength, at 25 strength the stat's modifier is 0.4342289734.
$Bonus damage = 104 * 1.4 / 100 * 0.4342289734 * 190$
This gives us a bonus damage of ~120.13 or 120.
*I haven't tested with intelligence or faith*
