Swimming Pool Calculator API
Swimming-pool maths as an API, computed locally and deterministically. The volume endpoint computes the water volume of a rectangular, round or oval pool — in litres, US gallons and cubic metres — from the dimensions and either an average depth or separate shallow and deep depths (it averages them), in feet or metres. The dose endpoint computes how much of a chemical to add to raise a level by a target ppm: give the pool volume and the desired increase, and either the product strength percent or a preset (cal-hypo, dichlor, trichlor, liquid chlorine, bleach), and it returns the amount in grams, kilograms, ounces and pounds. The salt endpoint computes the salt needed to reach a target salinity in a saltwater pool from the current and target ppm, in kilograms and pounds (and 40 lb bags). Everything is computed locally and deterministically, so it is instant and private. Dosing depends on the actual product strength and your test readings — always follow the product label, add in stages and re-test before adding more. Ideal for pool-service and maintenance apps, pool-builder and retailer tools, and smart-pool and home-automation systems. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is pool maths; for general volume or unit conversion use a unit-conversion API.
