# Tutorials/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 Minecraft.

## Time

To convert time in Minecraft to time in real life, simply divide by 72, and vice versa.

Minecraft Time Real Time Ticks
3.6 seconds = 0.05 seconds = 1
1 minute ≈ 0.83 seconds ≈ 17
1.2 minutes = 1 second = 20
1 hour = 50 seconds = 1,000
1.2 hours = 1 minute = 1,200
1 day = 20 minutes = 24,000
3 days = 1 hour = 72,000
1 week ≈ 2.33 hours = 168,000
1 lunar cycle (8 days) ≈ 2.67 hours = 192,000
1 month (30 days) = 10 hours = 720,000
72 days = 1 day = 1,728,000
1 year (365 days) ≈ 5.07 days = 8,760,000
504 days (1.38 years) = 1 week = 12,096,000
2160 days (5.92 years) = 1 month = 51,840,000
1 decade ≈ 50.69 days ≈ 7.22 weeks = 87,600,000
72 years (26280 days) = 1 year = 630,720,000
1 century ≈ 1.39 years = 876,000,000

## Amount of items

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, melon slices, wheat, dried kelp)
• 1 stack = 64 items = 7 blocks, 1 item. This applies to non-stackable and partially-stackable items as well. e.g. 64 water buckets = 1 stack of water buckets, even though water buckets do not actually stack in-game.
One stack of a fully-stackable material (e.g. stone, diamond) will fully occupy one slot in one's inventory.
• 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 = 43 or 1.3 full chests = 36 stacks = 2,304 items.
• 1 full double chest = 2 chestfuls = 54 stacks = 3,456 items.
• 1 chestful of shulker boxes = 27 chestfuls = 729 stacks = 46,656 items.
• 1 chunk = 37 chests and 25 stacks = 1024 stacks = 65,536 items.
• 1 stack of chests = 64 chestfuls = 1,728 stacks = 110,592 items.
• 1 chest squared = 1 chestful of chests = 1,728 chestfuls = 46,656 stacks = 2,985,984 items.
• 1 chunk of chests = 65,536 chestfuls = 4,194,304 stacks = 113,246,208 items.
• 1 chest cubed = 1 chestful of chestfuls of chests = 1,728 chestfuls of chests = 46,656 chestfuls = 80,621,568 stacks = 5,159,780,352 items.
• 1 world = ~59.81688255 chests5 = ~103,363.57304950 chests4 = ~178,612,254.22953818 chests3 = 8,138,020,833.3 chunks of chests = 308,641,975,308.641975308 chests2 = 14,062,500,000,000 chunks = 533,333,333,333,33313 chestfuls = 14,400,000,000,000,000 stacks = 921,600,000,000,000,000 items.
More conveniently: 59 chests5, 22s3 chests4, 15s30 chests3, 6s12 chests2, 17s21 chests and 9 stacks 0 items.
• 1 world of chests = 921,600,000,000,000,000 chestsful = 24,883,200,000,000,000,000 stacks = 1,592,524,800,000,000,000,000 items.

Note: 1 chunk is a 16×16×256 piece of a Minecraft map.

## Health

Main article: Health

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

Damage/entity HP
Chicken 4
Item 5
Instant Damage 6
Diamond Sword 7
Netherite Sword 8
Cow 10
Player 20 × 10
Enderman 40 × 20
TNT 65 × 32.5 max
Iron Golem 100 × 50
Ender Dragon 200 × 100
Wither 300 × 150 [JE only] 600 × 300 [BE only]
Player with maximum Health Boost and maximum Absorption 2068 × 1034
`/kill` 3.4028234663852886E38 × 1.7014117331926E+38 (max value of double `0x7F7FFFFF`)

## Hunger

Main article: Hunger

Similarly, the basic unit in hunger is a food point—1 ()—displayed as a chicken drumstick.

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.

## Speed

## Distance

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

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

### Metric units

Length Blocks Pixels
1 kilometer 1000 blocks 16000 pixels
1 hectometer 100 blocks 1600 pixels
1 decameter 10 blocks 160 pixels
1 meter 1 block 16 pixels
1 decimeter 0.1 blocks 1.6 pixels
1 centimeter 0.01 blocks 0.16 pixels
1 millimeter 0.001 blocks 0.016 pixels
6.25 cm 0.0625 blocks 1 pixel
62.5 cm 0.625 blocks 10 pixels
6.25 m 6.25 blocks 100 pixels
Blocks Volume
1 block 1 m3
1 block 1000 litres

### Imperial/U.S customary units
