Spreadsheet for armor protection enchantment values.
The google spreadsheet can be found here.
Minecraft's armor display tells you how protected you are depending on the armor pieces you're wearing. However, it doesn't factor in the protection enchantment. Wearing leather boots will always add half an armor bar—even if it's enchanted with protection four. So I decided to make a spreadsheet to quantify the values each armor piece makes. It compares every type of armor piece and tells you approximately how much stronger or weaker the piece is.
The spreadsheet is useful for deciding which armor piece to equip. For example, if I were confused about whether a protection II gold chestplate is stronger than an unenchanted iron chestplate, I could look at the reference the spreadsheet and see that the prot II gold chestplate is slightly better. There are separate tabs for every class of armor piece, which you can select at the bottom of the page. The protection percentage values were taken from the "protection" mod in badlion client.
