Converters
Heat Flux Converter
Convert W/m², kW/m², W/cm², BTU/h·ft², and calorie-based heat flux units with a browser-local 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 heat-transfer examples, solar notes, HVAC references, materials documentation, and engineering handoffs.
Heat Flux Converter workflow tips
Use this converter when heat-transfer, solar, HVAC, or materials notes mix W/m², kW/m², W/cm², BTU/h·ft², and calorie-based units.
Normalize heat-transfer rates
Convert the source measurement here, then use Thermal Conductivity Converter, Power Converter, Area Converter for adjacent technical conversions.
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, or server-side processing are used.
What this tool does
Convert heat flux values for heat-transfer examples, solar notes, HVAC references, materials documentation, and engineering handoffs without uploading anything.
Common use cases

Privacy note
Client-side only: unit conversion runs in your browser and entered values are not uploaded, stored, fetched, or logged. Results are informational conversion helpers.
FAQ
Does this heat flux converter upload my values?
No. Conversion runs locally in your browser and does not upload, store, fetch, or log entered values.
Can I swap the units?
Yes. Use the Swap units button to reverse the source and target units without retyping the value.
Are the results exact?
The tool uses standard conversion factors and rounds displayed output for readability. Verify critical engineering, compliance, medical, legal, tax, or safety decisions separately.
