About

we built smithmetic because every calculator site online is slow, cluttered, and stuck in 2008.

we wanted something different — instant answers, clean design, zero clutter. type what you need, get your answer, move on.

how it works

type a calculation directly into the search bar — 180c, 20% of 50, tip on 45 — and get your answer instantly. no page reloads, no waiting.

every calculator runs at the edge on cloudflare workers. sub-50ms responses globally. the math happens before the page finishes loading.

by the numbers

100+ calculators across 5 categories — converters, finance, math, health, and countdowns. growing every week.

the tech

no bloated javascript frameworks. no cookie banners. no layout shift. just server-rendered html, a tiny script for live calculations, and inline css. the entire page loads in a single request.

the name

smith + arithmetic = smithmetic. we did the math.
