# CalcsLive

> CalcsLive is a unit-aware calculation platform for engineers and e-commerce product pages. It allows anyone to create, share, and embed interactive calculators with live unit conversion across 570+ units in 67 categories — no coding required.

## What CalcsLive Does

CalcsLive lets users write calculation articles where variables have units. When a reader changes an input value or switches a unit (e.g. from kg to lbm), all dependent calculations update in real time. This makes it useful for:

- **E-commerce product pages** — Help customers choose the right size or quantity before purchase, reducing returns and support tickets
- **Engineering documentation** — Share live calculations that readers can interact with
- **Education** — Embed unit-aware math examples in blog posts and course materials
- **Automation** — Use calculations as stateless functions via API (n8n, Node-RED, HTTP)
