- 1 Wurm year = 336 Wurm days = 42 real days
Distance, Slopes, and Height
- The standard measurement designated to measuring distance in Wurm is the “tile”. Tiles are the equally sized squares that the landscape of Wurm Online is entirely composed of. In the 3D world of Wurm a tile can be either flat or inclined, so that one or more of its corners can be higher or lower than the others.
- A relatively flat tile represents what in real-life would be a 4 meter by 4 meter square. Subsequently, 250 tiles then equals what would be, in real-life, 1 kilometer.
- Exact linear distance can easily be gleaned by using a spyglass, as this tool will display the exact distance between the user and any distant object targeted within its viewing crosshairs. See picture for example:
However, when it comes to measuring heights and slopes, the spyglass is not quite accurate enough to always yield reliable results. Triangulation is thus recommended in such situations:
To use triangulation to determine the height (H) of an object, you must first define a reference point. To do so, take a screenshot (as shown in the example) and measure the angle (α) between the ground and the top of the object, as seen from the reference point. As we have no means to measure angles in-game, we need to use a graphics program to determine the angle on the screenshot. Additionally you need to measure the horizontal distance, which you obtain by counting the number of tiles T (remember: one tile corresponds to a distance of 4 meters). You then get the height H by using this formula:
H = T tan α
Here is an example: For a distance of 40 tiles (T=160m) we measure an angle of 14°. Thus, our avatar of Magranon would have a height of:
H = 160m ● tan(14°) = 40m
(Please note that the result has to be rounded, due to the immanent inaccuracy of this method.) Here is a list of heights for some arbitrary objects, just to give some examples:
| Object | Height (m) |
|---|---|
| Player character | 1.7 |
| House wall (1 floor) | 3.0 * |
| Pillar | 5.6 |
| Freedom tower (incl. flag) | 25 |
| Colossus | 34 |
| Deity avatar | 40 |
*) Note: the ground floor of a house has a height of 3.3 m
- Finally, talking about measuring heights, we must look at another basic unit of measurement used in the Wurm world: “dirts”. Whenever we see sloped tiles defining the 3D landscape, the elevation of slopes is given in terms of the amount of “dirts" dropped. When terraforming the land you use a shovel to dig or drop dirt - you add or subtract one “unit of dirt” with each action of the shovel.
- Using the method of triangulation described above, we can find out how these “units of dirt” correspond to metric units. By dropping dirt, we make elevated platforms of various heights thus creating different slopes. We then position an observer in a pit, so that the eye level is slightly above the ground, and take screenshots:
..... 
Measuring the angles and using the formula given above, we can triangulate the elevation of the platform:
..... 
We obtain the following table (for slopes spanning a single tile):
| Slope | Angle | Elevation (m) |
|---|---|---|
| 10 | 14.0 | 1.0 |
| 20 | 26.6 | 2.0 |
| 30 | 36.9 | 3.0 |
| 40 | 45.0 | 4.0 |
| 50 | 51.3 | 5.0 |
| 60 | 56.3 | 6.0 |
| 70 | 60.3 | 7.0 |
| 80 | 63.4 | 8.0 |
| 90 | 66.0 | 9.0 |
| 100 | 68.2 | 10.0 |
| 150 | 75.1 | 15.0 |
| 200 | 78.7 | 20.0 |
Thus, there is a simple relation between “dirts” and metric units:
1 meter = 10 dirts.
Using this method, it is also possible to determine the height of a player character with sufficient accuracy:
Volume
Volume is a measurement of how much space an item takes up. This measure is often not displayed in-game. Bulk bins are the one exception.
More Notes on Volume in Wurm:
- Liquids happen to be 1kg to 1L (weight to volume), and because of this, are often referenced in liters (L). Many sold items have different kg to L relationships. Examples:
- A small bucket can hold 12 L. A full bucket of water containers 12 L of water weighting 12 kg.
- A pottery bowl can hold 9 L and weights 0.50 kg. A filet of fish is 0.20 L and weights 0.30 kg. Thus, a pottery bowl can hold 45 filets (9 / 0.2 = 45) and will weight 14 kg (13.50 kg filet, 0.50 kg bowl).
- Volume puts limits on how much can fit in a container. All containers themselves consume slightly more volume then they hold. Hypothetically players can carry infinite volume and containers can hold infinite weight.
- You can calculate how many of an item will fit in a container by dividing the container's volume by the stored item's volume. See the Container page for a list of containers and volume capacities.
Time, Seasons
- The world of Wurm rotates rapidly around its axis: approximately 8 times faster than the real-life Earth. As a result, the following statements are true:
1 real day = 8 Wurm days AND 1 Wurm day = 3 real hours
1 real hour = 8 Wurm hours AND 1 Wurm hour = 0.125 real hours (7.5 real minutes)
- For more help with time, see the following Game Time Conversion Table:

- The Wurm world also experiences 4 different seasons called “winter”, “spring”, “summer”, and “autumn”. These seasons reoccur regularly after 336 Wurm days. As such:
1 Wurm year = 336 Wurm days = 42 real days.
- This is a convenient number, because 336 = 7 x 4 x 12, allowing us to split a Wurm year into 12 months (called “starfalls”), each with 4 weeks of 7 days. As such:
1 Wurm year = 12 starfalls
1 starfall = 4 Wurm weeks = 3.5 real days
1 Wurm week = 7 Wurm days = 21 real hours.
- The 7 days in a Wurm week are called:
- 1. day: Day of the Ant
- 2. day: Day of Luck
- 3. day: Day of the Wurm
- 4. day: Day of Wrath
- 5. day: Day of Tears
