About EasyUnits

EasyUnits is a free online unit converter designed to be the fastest, simplest way to convert between measurement units. No sign-up, no ads, no data collection — just type a value and get your result instantly.

We cover 13 measurement categories — Length, Weight, Temperature, Speed, Volume, Area, Pressure, Energy, Power, Time, Digital Storage, Data Transfer, and Fuel Consumption — with over 100 individual units. Every conversion factor is sourced from internationally recognized standards including the International System of Units (SI) and the National Institute of Standards and Technology (NIST).

Why we built this

Most unit converter sites are cluttered with ads, pop-ups, and unnecessary complexity. We wanted a tool that loads fast, looks clean, and gives accurate results without distractions. EasyUnits is that tool.

The entire site is statically generated, meaning every page loads near-instantly on any device. There are no server-side calculations or delays — your browser does the conversion math locally the moment you type.

Accuracy

All conversion factors are based on exact definitions where available (e.g. 1 inch = 25.4 mm exactly) and on the best available scientific values for derived units. Results are displayed to up to 6 significant figures. Temperature conversions use exact formulas with Kelvin as the intermediary.

Open and free

EasyUnits is and will remain completely free to use. We don't track you, we don't sell your data, and we don't show ads. Bookmark your most-used conversions for one-tap access from any device.
