Tutorial:Units of measure

This tutorial is designed to compare units of measurement in Minecraft to real life units and to compare different units used in-game.

To convert time in Minecraft to time in real life, simply divide by 72. To do the reverse, multiply by 72. To measure ticks in Minecraft, multiply the real time (seconds) by 20 (this doesn't factor in lag and assumes a constant 20tps).

1 item is the most basic measurement in quantity.

• 1 block = 9 items. Used for resources that can be crafted into storage blocks and back (most kinds of processed minerals, slimeballs, bone meal, wheat, dried kelp)
• 1 stack = 64 items = 7 blocks, 1 item. Note that some items like banners, signs, eggs, and ender pearls only stack to 16. So if someone says they have a stack of eggs, they have 16. For unstackable items, a stack is just 1.

One stack of a fully-stackable material (e.g. stone, diamond) will fully occupy one slot in one's inventory. A bundle, added in the Bundles of Bravery update, allow different types of items as long as the total is 64 with 16 stackable items taking up 4 of the bundle’s slots & unstackable items taking all 64; empty bundles aren’t stackable but are treated as if they are 16 stackable inside bundles & bundles with contents can’t go in other bundles.

• 1 item = 9 nuggets
• 1 full hopper = 5 stacks = 320 items.
• 1 stack of blocks = 9 stacks = 576 items when completely uncrafted.
• 1 full dispenser or dropper = 9 stacks = 576 items.
• Mining capacity of an unenchanted diamond pickaxe = 24 stacks 25 items = 1561 items.
• 1 full chest = 27 slots or 27 stacks = 1,728 items.
• Mining capacity of an unenchanted netherite pickaxe = 31 stacks 47 items = 2031 items
• 1 inventory = 37 stacks = 2,368 items, when the offhand is included.
• 1 full double chest = 2 chestfuls = 54 stacks = 3,456 items.
• 1 chestful of shulker boxes = 27 chestfuls = 729 stacks = 46,656 items.
• 1 double-chestful of shulker boxes = 54 chestfuls = 1458 stacks = 93,312 items.

A useful tool to convert different units in the game can be found on https://gamertools.net/tools/1.

The basic measure of health is one health point (1HP👁 💔
). One heart (2HP👁 ❤️
) is also commonly used when talking about health.

Similarly, the basic unit in hunger is a food point—1 (👁 🍖
)—displayed as a ham shank.

A full hunger bar (20 (👁 🍗
× 10)) contains 20 food points.

Additionally there are another 20 saturation points, which are invisible but are used when performing actions before hunger, so the maximum value is 40.

Minecraft's worlds are a voxel grid where each block represents a voxel which is one cubic meter (1m³).

Knowing that one block is one cubic meter, we can derive that:

• Note that a water block is 0.9 m³ because it is 0.9 meters high.

Using the /attribute command, you can convert gravity in Minecraft to gravity in real life, simply divide by 0.08. To do the reverse, multiply by 0.08. Earth's gravity is 9.81m/s² The surface gravity on Earth is 1g.

In modded Minecraft there are some more units, that don’t exist in vanilla Minecraft. The most common are millibuckets (mB) and redstone flux (RF). One bucket equals 1000 mB, while RF can‘t be defined by the vanilla game. Millibuckets is the only known measurement of fluids, while there are many more units for energy with different names, like Forge Energy (FE), Energy Units (EU) or some, which describe rotational power, like SU.
