Unit Converters

Convert between units instantly, with the real formulas shown on every page. These converters run entirely in your browser — type a value on either side and the other side updates, with a conversion table for the common values. The first live converters cover length and other everyday units, each with its own conversion table and the formula shown. Later batches add length, weight, temperature, volume, area, speed, time, data storage, currency helpers and cooking measures, each with its own table and FAQs for that unit pair. Every converter shows its formula instead of hiding it, so you can check the math yourself. Nothing is uploaded, there is no sign-up, and the converters keep working offline once the page has loaded. Whether you are converting land for a deed, weights for a recipe, or temperatures for a science problem, the converter shows its work and keeps a history of nothing — your values disappear when you close the page.
