Utility Tools
Date, time, GPA, grade, and general-purpose utility calculators.
Utility is a small, genuinely miscellaneous category — carbon and water footprint, electricity cost, rent splitting, typing speed, unit pricing. These are everyday calculations that don't fit neatly under Finance, DIY, or any other themed category, but come up often enough to be worth a dedicated tool rather than mental math.
Most visitors here are solving a specific one-off problem — splitting a utility bill fairly among roommates, checking whether the bulk size is actually cheaper per unit, or estimating a household's carbon footprint — rather than researching a broader topic.
