About UnitCraft

Last updated: June 29, 2026

What it is

UnitCraft is a free toolkit of CSS calculators for front-end developers and design-system teams. Convert PX to REM, generate fluid typography with clamp(), check WCAG contrast ratios, map Tailwind spacing, and solve viewport math — all without leaving your browser.

Who built it

UnitCraft is built and maintained by Akash Yadav, a front-end engineer focused on practical CSS tooling. Formulas match browser DevTools behavior and are validated against published CSS specifications.

Privacy by design

Every calculator runs entirely client-side. Your inputs are never uploaded to a conversion server. No account is required. See our privacy policy for details.
