What is analogon.io?

analogon.io is a free, no-registration unit converter designed to be fast, distraction-free, and genuinely useful. It covers the ten measurement categories that people convert most often — length, weight, temperature, area, volume, speed, time, digital storage, pressure, and energy — and includes dedicated conversion pages for every pair of units within each category. Whether you need to know how many kilometers are in a mile, what 350 °F is in Celsius, or how many gigabytes are in a terabyte, you will find a direct, clearly explained answer here.

Why we built it

Unit conversion is one of those tasks that comes up constantly — in cooking, travel, construction, science, medicine, and everyday shopping — yet many existing tools bury the answer in cluttered pages, demand JavaScript frameworks that load slowly, or require you to navigate several menus before you get a result. We wanted something that works immediately: type a number, get an answer, and optionally read a clear explanation of what the units mean and where the conversion factor comes from. analogon.io is built as a fully static site, so every page loads instantly and works even on slow connections.

Accuracy and sources

All conversion factors are based on the official definitions of the International System of Units (SI), the international yard and pound agreement of 1959, and the United States customary unit definitions. Linear conversions (length, weight, area, volume, speed, time, digital storage, pressure, and energy) use exact or near-exact multiplication ratios. Temperature conversions use the precise formulas specified by the SI: °F = (°C × 9/5) + 32 and K = °C + 273.15. Where a conversion factor is defined exactly by international agreement — such as 1 inch = 2.54 cm or 1 pound = 0.45359237 kg — we use the exact value. Where a factor is rounded (such as average month length), we document the approximation clearly.

Digital storage units present a specific ambiguity: computing systems traditionally use binary multiples (1 KB = 1,024 bytes), while storage manufacturers use decimal multiples (1 KB = 1,000 bytes). analogon.io uses the binary definition (powers of 1,024) for kilobytes, megabytes, gigabytes, and terabytes, consistent with how operating systems report file sizes — and we note this distinction in the educational content on each relevant page.
