* To calculate the weight a piece of armor or a weapon would be if made of one of these meterals, look up the weight of that item in the PHB (Player’s Handbook). Then find the material in the above table and look under the “Weapon or Armor weight” column. If it says “Same as steel” then it will weigh the same as the one in the PHB. Otherwise change the weight as indicated.

There are 1,728 cubic inches in a cubic foot. We can round that off to 2,000.

To make a quick estimate of the weight of an item, it is often easer to work in cubic inches than it is to work in cubic feet. Divide the weight per cubic foot for the material (in the table above) by 2,000. Then multiply the resulting fraction by the number of cubic inches of material in the item. Round this down to an even pound.

For metals, you can get the value of the item by multiplying the weight of the item by the metal’s value per pound (here).
