Work To Make
Work To Make is a Stat: The base amount of work it takes to make an item, once all materials are gathered.
This value is defined in the game files in ticks, but is displayed in-game as the rounded conversion into seconds. Note that this rounding is cosmetic only, the true work time is precise to the tick value.
One second in-game, at normal game speed, corresponds to 60 ticks. Thus, conversion is a simple matter of dividing by 60 for conversion from ticks to seconds, and multiplying by 60 for conversion from seconds to ticks. For example, a charge lance has a Work To Make stat defined as 60,000 ticks in the fame files, and will therefore display in-game in the bills selection, which uses in-game seconds as the unit, as 1000 work.
For reference, an in-game day is 1000 seconds long at normal game speed, corresponding to 60,000 ticks. Thus at 100% work speed, exactly 1,000 units of work will be performed during one in-game day of uninterrupted work. Assuming a regular "work shift" of about 12-16 in-game hours, one can expect about 500-650 units of work to be performed, per day, by a pawn on a regular schedule working at 100% speed.
Lastly, note that pawn stats, such as general labor speed or cooking speed, divide this base value to find the actual amount of time to make an object. For example, if a pawn has 200% of the relevant speed, then it will take half the time to make the item than is reported by its Work To Make stat.
