About Radioactivity
Radioactivity counts how many atoms decay each second. One becquerel is a single decay per second, which is tiny, so real sources are quoted in kilo- or megabecquerels. The older curie was based on a gram of radium and is far larger: 1 Ci is 37 billion becquerels. A household smoke detector holds roughly 30 kBq.

Frequently asked questions
- How many unit categories are supported?
- Over 75, from everyday units (length, mass, temperature, volume, area, speed, data storage) to technical and scientific ones (energy, pressure, torque, viscosity, molar concentration, luminance, and more).
- Does it convert engineering and scientific units?
- Yes. Alongside common units it covers engineering and scientific categories — force, pressure, torque, thermal, flow, radiology, and CSS/typography units — with precise conversion factors.
- Are the conversions accurate?
- Yes. Conversions use standard factors and precise formulas, including non-linear ones like temperature, so results are exact.
- Do I need to install an app?
- No download needed — it's a free web app that runs in any modern browser on phone, tablet, or desktop, with nothing to install and nothing sent anywhere.
