Heat Flux Converter

What is the heat flux converter?

The heat flux converter is a collection of calculators for changing one heat flux unit into another. Convert heat flux density units for heat transfer, solar radiation, thermal systems, furnaces, and engineering analysis.

Heat flux conversions are used for heat transfer, solar loading, furnaces, thermal protection, process equipment, and engineering analysis.

Available heat flux units

This category includes the following units:

• Watt per Square Meter (W/m2)
• Kilowatt per Square Meter (kW/m2)
• Watt per Square Centimeter (W/cm2)
• BTU per Hour Square Foot (BTU/h ft2)
• Calorie per Second Square Centimeter (cal/s cm2)

Common heat flux use cases

Use this category when the same measurement appears in different unit systems, data sheets, calculators, reports, or regional conventions.

• Heat Flux conversions help compare measurements across specifications, calculators, labels, and technical references.
• Use this category when source data and target documents use different heat flux units.
• The dedicated conversion pages show formulas, examples, tables, related pages, and FAQ for individual unit pairs.

Common heat flux conversion mistakes

Most wrong answers come from mixing unit systems, rounding too early, or choosing a unit that looks similar but means something different.

• Do not hide the original heat flux unit when copying a result into a report, label, or calculator.
• Do not round intermediate values when the result will be reused in another formula.
• Check whether the source and target units describe the same physical quantity before comparing heat flux values.
