Omni Unit Converter — 33 Pro Categories, One-Time Purchase, Forever Ad-Free Tired of clunky websites, intrusive ads, and forced subscriptions just to convert a few units? Omni Unit Converter is a professional, all-in-one measurement tool built for speed and precision. It covers everything from everyday life to engineering, science, and academic work — with a single one-time purchase. No subscriptions, no ads, and absolutely no tracking of your data. Open it and go: results appear instantly, accurately, and cleanly, every single time.

Why Omni Unit Converter? Most converters are either too basic or buried under ads and paywalls. We took the opposite path. For less than the price of a coffee ($1.99), you get all 33 complete categories, hundreds of units, and 28 interface languages — all unlocked at once. No in-app purchases, no monthly fees, no "premium" upsell. Updates stay free. A great tool should let you focus on your work, not on paying for features or dodging ads.

33 Categories — Everything You Can Think Of Everyday: Length, Area, Volume, Mass (Weight), Temperature, Speed, Time, Pressure, Angle. Perfect for cooking, shopping, travel, fitness, and home projects. Data & Network: Data Storage and Data Transfer Rate. We carefully separate decimal (KB/MB/GB, base-1000) from binary (KiB/MiB/GiB, base-1024) — finally clearing up the classic "advertised vs. actual drive capacity" confusion. Engineering & Physics: Power, Energy, Force, Torque, Flow Rate, Mass Flow Rate, Acceleration, Density, Frequency, Fuel Economy. Electrical: Voltage, Current, Resistance, Conductance, Capacitance, Inductance, and Charge (battery capacity in mAh/Ah). Optical: Illuminance, Luminous Flux, Luminous Intensity, and Luminance (nits) — ideal for lighting design and screen specs. Every category includes units from SI to imperial, all verified for numerical accuracy you can trust in real engineering and scientific work.

Built for Precision All conversions are based on authoritative standard coefficients and validated to near-zero relative error. Scientific notation, high-precision decimals, and localized number formats (decimal points and thousands separators) are all handled smartly. Tap any result to instantly reuse it as your next input for seamless chained conversions.

28 Languages, Fully Offline, Privacy First The app works completely offline — on planes, subways, or anywhere with no signal. Nothing is uploaded, tracked, or collected. Your inputs stay yours. The interface supports 28 languages and follows your system language automatically.
