Temperature scale
Dwarf Fortress uses its own temperature scale in most cases, often called "Degrees Urist" on this wiki. So if you see something like [HOMEOTHERM:10067], don't be amazed.
Magma's temperature is 12,000° Urist.
The highest possible temperature in Dwarf Fortress is 60,000°U - the temperature 60,001°U is used internally for temperatures which have been set to "NONE".
Conversion
[DF scale] = [FAHRENHEIT] + 9968
[DF scale] = [CELSIUS] * 9/5 + 10000
[DF scale] = [KELVIN] * 9/5 + 9508.33
[DF scale] = [RANKINE] + 9508.33
Reference Chart
| Significance | DF Scale | Fahrenheit | Celsius | Kelvin | Rankine |
|---|---|---|---|---|---|
| Human Body Temperature | 10066.62 | 98.6 | 37.0 | 310.15 | 558.27 |
| Freezing Point of Water | 10000 | 32 | 0 | 273.15 | 491.67 |
| Boiling Point of Water | 10180 | 212 | 100 | 373.15 | 671.67 |
| Absolute Zero | 9508.332 | -459.67 | −273.15 | 0 | 0 |
| DF Scale's Zero1 | 0 | -9968 | -5555.555... | -5282.40555... | -9508.33 |
- 1 - Yes, temperatures in Dwarf Fortress can go far, far below absolute zero, which is physically impossible. Considering Dwarf Fortress also allows Template:L, it's best not to ask questions.
- 2 - Technically, fractional/decimal temperatures are not possible in Dwarf Fortress, as they are stored as unsigned 16-bit integers. For instance, body temp for humans in the raws is rounded to 10067.
Some general information about temperatures in DF (copied from somewhere on the forums):
| Event / location | Temperature |
|---|---|
| water freezes | 10000 U |
| underground | 10015 U |
| outside (varies) | 10048 U |
| dwarf/human body temp | 10067 U |
| floor above magma | 10075 U |
| water boils | 10180 U |
| magma | 12000 U |
Melting point
This is the temperature at which an object will melt. Any material with a melting point over 12,000 °U is Template:L.
Boiling point
This is the temperature at which an object will evaporate.
Ignition point
This is the temperature at which an object will catch fire.
Heat damage point
This is the temperature above which an object will begin to take Template:L. Flammable items without a heat damage point (or with an exceptionally high one) will take damage very slowly, causing them to burn for about 9-10 months before disappearing.
Cold damage point
This is the temperature below which an object will begin to take Template:L.
Specific heat
This determines how long it takes an object to heat up or cool down. An object with high specific heat will change temperature more slowly.
