Calcgrid

Use this when a user needs a deterministic calculation but none of the dedicated tools clearly matches and the calculator_id is unknown. Search 737 calculators from the complete task in English or Chinese, then call run_calculator with the top matching calculator_id and returned input_hints. Do not use this for trivial arithmetic, live data, writing tasks, or when a dedicated typed tool already matches. This tool only discovers; it does not calculate.

List all calculators, optionally filtered by category id (finance, health, fitness, math, geometry, statistics, conversion, physics, chemistry, everyday, food, construction, business, time, medical, engineering, weather, investing, developer, energy, photography, science, gaming, lunar, yijing). Returns calculator_id, name, description, use_when and required inputs for each. Use it to browse a whole category; use search_calculators for keyword lookup. Does not perform calculations.

List the calculator categories with id, name, description and calculator count. Use it to orient before list_calculators. Does not perform calculations.

Use this before a working-day or business-day task to select the correct evidence package. It distinguishes the worldwide CLDR weekday/weekend baseline, the broad source-labelled OpenWorkdays national-scope reference, the clearly labelled OpenHolidays nationwide public-holiday reference, and the official public-holiday calendars for mainland China, Singapore, Australia, the US, Canada, Japan, India's central government, UAE federal government, New Zealand, South Africa, Ireland plus the UK. The result contains one machine-readable route per CLDR territory, or one route when the optional territory filter is supplied, including whether holiday semantics are unsupported, reference-only, or require a jurisdiction-specific input such as the UK division, Australian state/territory or Indian office scope. US is OPM federal scope only; CA is Canada Labour Code federally regulated-employer scope and does not infer substitute days; JP is statutory national holidays only and does not infer employer closures; IN preserves Gazetted/Restricted classes and does not infer state/UT or local optional selections; AE is UAE federal-government scope with exact 2026 dates only and does not infer local/private schedules or unresolved lunar dates; NZ is national statutory dates only and does not infer regional anniversary days; ZA is national public holidays over a Monday-Friday baseline and does not infer employer holiday exchanges; IE excludes Good Friday and does not infer next-working-day closures for weekend holidays. This is read-only catalogue discovery; it does not calculate a date or count and must not be reported as a calculation success.

Use this only after search_calculators when its input_hints do not resolve a range, enum or optional-field question. Return the full input/output schema, formula, sources, examples and limitations for one calculator. Do not call it when the search result already supplies enough input detail; call run_calculator instead. This tool only describes and does not calculate.

Use this when the user needs one of Calcgrid's 737 deterministic calculators and no dedicated typed tool covers it. Call it immediately after search_calculators once calculator_id and input_hints are known; do not stop at search or schema discovery. Do not use it for trivial arithmetic, live rates or unrelated tasks. Returns typed values with units, formula, sources, freshness and timestamp; validation errors identify the field and a repair hint.

Use this when the user asks to convert a numeric value between units of the same physical quantity: length, mass, temperature, area, volume, speed, time, data, energy, pressure, power, angle, fuel economy, force, frequency, density or torque. Unit symbols and common names are accepted. Do not use this for currency, live exchange rates or cross-quantity conversions that require density. Returns the converted value, detected quantity, exact factor and a conversion table.

List every unit symbol supported by convert_units, grouped by quantity, with names. Use it when a unit symbol is rejected with UNKNOWN_UNIT. Does not convert anything.

Use this when you need an SLA, support, procurement or order deadline measured in business hours under the published mainland China or UK calendar, and must express the result in another team's IANA time zone with reproducible holiday and DST evidence. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need calendar hours, an overnight or split shift, lunch breaks, an employer/local/market calendar, a legal filing deadline, actual delivery/arrival prediction, private calendar availability, or a date outside the selected evidence package's coverage. What it computes: Adds an explicit number of business hours inside a caller-supplied daily window, using either the official mainland China work calendar or a selected GOV.UK division, then returns the deadline in UTC, the calendar zone and a target IANA zone with a complete segment/skip audit trail. Example user requests: A Shanghai support ticket opened at 2026-09-24 15:00 has a 16-business-hour SLA, counted from that day during 09:00-17:00 China official working time.
