# Tutorials/Units of measure

(Redirected from Distance)

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 or multiply by 72 to convert time in real life to time in Minecraft.

Time in Minecraft Time in Real life
1 minute ≈ 0.83 seconds
1 hour = 50 seconds
1 day = 20 minutes
1 week ≈ 2.33 hours
1 lunar cycle ≈ 2.7 hours
1 month ≈ 10 hours
1 year ≈ 5.07 days
1 decade ≈ 50.69 days or 7.22 weeks
1 century ≈ 1.39 years
1 millennium ≈ 13.9 years

## Amount of items

1 item is the most basic measurement in quantity.

• 1 stack = 64 Items. This applies to non-stackable and partially-stackable items as well. e.g. 64 water buckets = 1 stack of water buckets, although they do not technically stack.
One stack of a fully-stackable material (e.g. stone, diamond) will fully occupy one slot in one's inventory.
• 1 full chest = 27 slots or 27 stacks = 1,728 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 chunk = ~37.926 chestfuls = 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 chestsful = 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 = ~14.9542 chests5 = ~25,840.8933 chests4 = ~44,653,063.5574 chests3 = 2,034,505,208.3 chunks of chests = ~77,160,493,827,1605 chests2 = 3,515,625,000,000 chunks = 133,333,333,333,333.3 chestsful = 3.6 x 1015 stacks = 2.304 x 1017 items.
• 1 world of chests = 2.304 x 1017 chestsful = 6.2208 x 1018 stacks = 3.981312 x 1020 items.

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

## 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 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)
Player with maximum Health Boost and maximum Absorption 2068 ( × 1034)
`/kill` 3.4028234663852886E38 ( × 1.7014117331926E+38) (max value of double `0x7F7FFFFF`)

## Hunger

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

A full hunger bar (20 ()) contains 20 food points.

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

## 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 liters
