Irradiance Converter
Convert W/m², kW/m², mW/m², W/cm², mW/cm², µW/cm², and BTU/h·ft² with a browser-local irradiance converter.
Client-side only: the conversion runs in your browser. Values are not uploaded, stored, fetched, or logged.
Base unit: watt per square meter. Useful for radiometry notes, solar examples, optics references, sensor specs, and technical documentation.
Irradiance Converter workflow tips
Use this converter when optics, radiometry, sensor, or technical documentation mixes W/m², kW/m², mW/m², W/cm², mW/cm², µW/cm², and BTU/h·ft².
Normalize radiometry notes
Pair this converter with Radiant Flux Converter, Irradiance Converter, Radiance Converter, and Solid Angle 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 irradiance values for radiometry notes, solar examples, optics references, sensor specs, or technical documentation without uploading anything.
Common use cases
Convert irradiance units such as W/m², kW/m², mW/m², W/cm², mW/cm², µW/cm², and BTU/h·ft² locally in your browser. Use it when radiometry notes, solar examples, optics references, sensor specs, or technical documentation need quick unit normalization before cleanup, QA, or handoff.
