Volume & % full at a depth

Tank Volume API
Tank volume and fill-level maths as an API, computed locally and deterministically. The volume endpoint gives the total capacity — in litres, US gallons and cubic metres — of a vertical cylinder, horizontal cylinder, rectangular tank, sphere or capsule, from its dimensions in metres, centimetres, millimetres, feet or inches. The fill endpoint computes the volume of liquid and the percent full at a given fill depth, using the exact geometry for each shape — including the circular-segment formula for a horizontal cylinder (where the level is famously non-linear) and the spherical-cap formula for a sphere. The level endpoint is the inverse "dipstick" calculation: it finds the depth that corresponds to a target volume or a target percentage, solving the segment geometry by bisection. Everything is computed locally and deterministically, so it is instant and private. Ideal for fuel, water, oil and chemical tank monitoring, agriculture and irrigation, process and industrial tooling, and tank-gauging and dipstick apps. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tank-gauging geometry; for swimming-pool volume and chemical dosing use a pool API, and for plain unit conversion use a unit-conversion API.

API de Calculadora de Acuario
Matemáticas de acuario como API, calculadas local y determinísticamente. El endpoint de volumen calcula el volumen de agua de un tanque — en galones estadounidenses y británicos y litros — para un tanque rectangular, cúbico, cilíndrico, hexagonal o de frente curvo a partir de sus dimensiones (pulgadas por defecto, o centímetros, milímetros y metros), y aplica un factor de llenado (predeterminado 0.9) para sustrato, decoración y borde libre para dar un volumen neto realista. El endpoint de carga de peces da una carga aproximada a partir del volumen del tanque y la longitud total de los peces usando la guía clásica de pulgadas por galón, informando las pulgadas máximas recomendadas y qué tan cargado está el tanque. El endpoint de cambio de agua calcula el volumen de cambio de agua para un porcentaje, con una dosis opcional de declorador. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. La carga de peces es solo una guía aproximada para principiantes — la carga real depende de la especie, filtración y carga biológica. Ideal para aplicaciones de acuario y mantenimiento de peces, herramientas para tiendas de mascotas y aficionados, y planificadores de configuración de tanques. Cálculo puramente local — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto son matemáticas de acuario; para volumen de piscina y dosificación química use una API de piscina y para medición de tanques de almacenamiento use una API de tanque.

Geometry API
Berechnen Sie die Geometrie gängiger Formen. Ermitteln Sie die Fläche von 2D-Formen (Kreis, Quadrat, Rechteck, Dreieck – nach Basis/Höhe oder drei Seiten via Heron, Trapez, Parallelogramm, Raute, Ellipse, regelmäßiges Polygon), den Umfang oder den Kreisumfang, und für 3D-Formen das Volumen und die Oberfläche (Kugel, Würfel, Quader, Zylinder, Kegel, quadratische Pyramide). Übergeben Sie eine Form und ihre Maße und erhalten Sie das exakte Ergebnis sowie die verwendete Formel. Reine lokale Mathematik – kein Schlüssel, kein Drittanbieterdienst, sofort und deterministisch. Live. 6 Endpunkte. Entwickelt für CAD- und Engineering-Tools, Bildung und E-Learning, Bauwesen und Materialschätzung sowie jede App, die zuverlässige Formelberechnungen benötigt. Abgrenzung zu einem generischen Ausdrucksrechner oder Einheitenumrechner.

Tank Volume API
Tank-gauging geometry as an API, computed locally and deterministically. The horizontal-cylinder endpoint computes the liquid volume in a partially-filled horizontal cylindrical tank from the fill height, the radius (or diameter) and the length, V = L·[r²·acos((r−h)/r) − (r−h)·√(2rh−h²)] — the non-linear relationship that makes a horizontal tank read so unintuitively, e.g. a tank filled to a quarter of its diameter holds only about 20 % of its capacity, while half height is exactly half full. The vertical-cylinder endpoint gives the straightforward V = π·r²·h for an upright tank. The sphere endpoint computes the volume in a spherical tank filled to a height h as the spherical cap V = π·h²·(3r−h)/3, exactly half the sphere at h = r. Every response returns the liquid volume in cubic metres and litres, the full capacity, and the fill percentage. All lengths are in metres. Everything is computed locally and deterministically, so it is instant and private. Ideal for industrial, fuel-station, agriculture, water-utility, chemical-storage and process app developers, tank-gauging, dipstick-to-volume and inventory tools, and IoT level sensors. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tank volume by geometry; for flow rate through a pipe use a flow-rate API.

Chimney & Flue API
Chimney and flue sizing maths as an API, computed locally and deterministically — the draft and dimension numbers a stove installer, sweep or builder runs so a fire pulls cleanly and safely. The flue-size endpoint gives the minimum flue cross-section for a fireplace opening: at least a tenth of the opening area for a square or rectangular liner, a twelfth for a round one (which draws better) — a 36 × 30 inch opening needs about 108 square inches of rectangular flue, or a 10.7-inch round. The draft endpoint gives the theoretical draft from the stack effect, ΔP ≈ 3465 × height × (1/T_outside − 1/T_flue) with temperatures in kelvin, so a 6-metre chimney with 200 °C flue gas on a freezing day pulls about 32 pascals (0.13 inches of water column) — taller and hotter draws harder. The height endpoint applies the 3-2-10 rule: a chimney must finish at least 3 feet above where it pierces the roof and at least 2 feet above anything within 10 feet, whichever is higher. Everything is computed locally and deterministically, so it is instant and private. Ideal for hearth and stove-installer apps, chimney-sweep and inspection tools, building-design calculators, and DIY-safety sites. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational estimates — verify against your appliance listing and adopted code.
