Quick-and-easy mod to convert the in-game temperature units to Fahrenheit. This includes both the unit (°C to °F) and the actual values (so 15°C water is now 59°F as it should be). Specific heat values have also been modified, so actual gameplay should be identical to base game.

This version fixes a bug where resource patches don't get converted to farenheit therefore the game can crash on load.

I think that it is a dumb mod, but you should have it.
