Converters
Radiant Energy Converter
Convert nJ, µJ, mJ, J, kJ, Wh, BTU, and ergs with a browser-local radiant energy converter.
Client-side only: the conversion runs in your browser. Values are not uploaded, stored, fetched, or logged.
Base unit: joule. Useful for optical pulse energy, radiation dose notes, lab measurements, sensor references, and technical handoffs.
Radiant Energy Converter workflow tips
Use this converter when optical pulse energy, radiation dose notes, lab measurements, sensor references, or technical documentation mixes nJ, µJ, mJ, J, kJ, Wh, BTU, and ergs.
Normalize optical measurements
Pair this converter with Radiant Flux Converter, Radiant Exposure Converter, Spectral Radiant Flux Converter, and Spectral Irradiance Converter for adjacent browser-local measurement documentation.
Prepare clean copy
After converting values, use Prefix / Suffix Lines or Find and Replace Text to format measurement lists.
Keep it browser-local
The calculation happens in your browser only. No accounts, uploads, storage, fetching, or server-side processing are used.
What this tool does
Convert radiant energy values for optical pulse energy, radiation dose notes, lab measurements, sensor references, or technical handoffs without uploading anything.
Common use cases
Convert radiant energy units such as nJ, µJ, mJ, J, kJ, Wh, BTU, and ergs locally in your browser. Use it when optical pulse energy, radiation dose notes, lab measurements, sensor references, or technical documentation need quick unit normalization before cleanup, QA, or handoff.
