Cigar capacity from interior volume

Humidor API
Cigar-humidor maths as an API, computed locally and deterministically — the numbers behind storing cigars right, so you buy the correct humidor and keep it at the perfect humidity. The capacity endpoint works out how many cigars an interior holds: interior volume × a packing efficiency ÷ one cigar's volume, where a cigar is a cylinder of its ring gauge (in 64ths of an inch) and length — a 9 × 7 × 3 inch interior holds about 40 Toros (ring 50, 6 inch) at a realistic 0.62 packing, leaving room for air and a humidification device. The media endpoint sizes the humidification: about one 60 g two-way pack per 25 cigars, replaced roughly every two months, so a 40-cigar humidor wants two packs. The seasoning endpoint covers a brand-new humidor — its Spanish cedar must absorb moisture for about two weeks at 84 % RH (one seasoning pack per 25-cigar capacity, or the distilled-water wipe-down) before any cigars go in, or the dry wood will rob them. Everything is computed locally and deterministically, so it is instant and private. Ideal for cigar-shop and tobacconist apps, humidor-maker product pages, cigar-aficionado and collection-tracker sites, and buying guides. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. For room humidity or dew point use a psychrometric API.

Psychrometric Air API
Moist-air (psychrometric) thermodynamics as an API, computed locally and deterministically. The dewpoint endpoint computes the dew-point temperature and the saturation and actual water-vapour pressures from a dry-bulb temperature and relative humidity, using the Magnus-Tetens relation over water, es = 6.112·exp(17.62·T/(243.12+T)) hPa — the dew point is the temperature to which air must cool for water vapour to start condensing. The humidity-ratio endpoint computes the humidity ratio (mixing ratio) W = 0.621945·Pw/(P−Pw), the specific and absolute humidity, the vapour pressure and the moist-air enthalpy h = 1.006·T + W·(2501 + 1.86·T) kJ per kg of dry air, at any total pressure (default sea-level 101325 Pa). The wet-bulb endpoint computes the wet-bulb temperature with the Stull (2011) empirical fit and the wet-bulb depression, the gap between dry- and wet-bulb that widens as the air gets drier. Temperatures are in °C, relative humidity in %, pressures in Pa. Everything is computed locally and deterministically, so it is instant and private. Ideal for HVAC, building-physics, meteorology, drying, greenhouse and data-centre-cooling app developers, comfort and condensation-risk tools, and engineering education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is moist-air psychrometrics; for ASHRAE ventilation airflow use a ventilation API, for the WBGT heat-stress index a WBGT API and for the standard atmosphere an atmosphere API.

Grain Bin API
Grain-bin storage maths as an API, computed locally and deterministically — the bushel and weight numbers a farmer or elevator sizes storage by. The bushels endpoint measures a round bin: floor area × grain depth gives the cubic feet, and a cubic foot holds about 0.8036 bushels, so an 18-foot bin filled 20 feet level holds roughly 4,090 bushels — and grain heaped to a peak adds a cone of (1/3) × floor area × peak height, so a 4-foot peak adds about 270 more. The weight endpoint converts bushels to weight by the crop’s standard test weight — corn and sorghum at 56 pounds a bushel, wheat and soybeans 60, oats 32, barley 48 — so those 4,090 bushels of corn weigh 229,040 pounds, about 114.5 US tons or 104 tonnes; pass a measured test weight for light or heavy grain. Everything is computed locally and deterministically, so it is instant and private. Ideal for agriculture, grain-elevator, farm-management and ag-tech app developers, storage-capacity and inventory tools, and harvest software. Pure local computation — no key, no third-party service, instant. US units (feet, bushels, pounds). Live, nothing stored. 2 compute endpoints.

RAID Calculator API
RAID storage-array maths as an API, computed locally and deterministically. The capacity endpoint computes the usable and raw capacity, the storage efficiency and the fault tolerance of a RAID level — RAID 0 stripes for n×disk with no redundancy, RAID 1 mirrors to one disk and tolerates n−1 failures, RAID 5 gives (n−1)×disk with one-disk tolerance, RAID 6 gives (n−2)×disk with two-disk tolerance, and RAID 10 gives (n/2)×disk — and reports the minimum disks each level needs. The compare endpoint lays the levels side by side for the same disks and disk size so you can weigh capacity against redundancy. The rebuild endpoint estimates how long it takes to rebuild a single disk at a given rebuild speed, the window during which a second failure would lose data in RAID 5/6. Everything is computed locally and deterministically, so it is instant and private. Ideal for storage, NAS, server and IT-admin app developers, capacity-planning and procurement tools, and homelab calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is RAID array sizing; for data-transfer time use a transfer API.

Roulette Odds API
Roulette odds maths as an API, computed locally and deterministically and exactly — the payout, the true probability and the house edge behind every bet, the numbers a fair game tells you and a casino would rather you ignore. The payout endpoint gives a bet's payout, winning numbers, win probability and house edge for a European (single-zero) or American (double-zero) wheel: a straight-up number pays 35 to 1 but wins only 1 in 37, an edge of 2.70 % European or 5.26 % American, the same on almost every bet because the payout simply ignores the zeros. The expected-value endpoint turns a stake into its expected value — stake × (win probability × (payout + 1) − 1), always negative and equal to minus the stake times the house edge — so €10 on a single number on a European wheel is worth −€0.27 every spin. The martingale endpoint exposes the doubling system: total risked = base × (2^steps − 1), the bet that explodes after a losing streak, and the bust probability — proof on the maths that no progression beats the zero. Everything is computed locally and deterministically, so it is instant and exact. Ideal for casino-game and odds apps, gambling-education and responsible-play tools, game-design back-ends, and probability teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational — not betting advice; the house always wins long-run.
