Heat Flux converter

kilowatt per square meter to watt per square meter

Convert kilowatt per square meter (kW/m²) to watt per square meter (W/m²). Use an editable heat flux converter, conversion formula, and reference table.

1,000

1 kW/m² = 1,000 W/m²

Calculated in your browser

Conversion formula

W/m² = kW/m² × 1,000

One kilowatt per square meter equals 1,000 watt per square meter. Multiply your value in kilowatt per square meter by this factor to get watt per square meter. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 kilowatt per square meter:
5 × 1,000 = 5,000 W/m²

About these measurements

Heat flux is thermal power per unit surface area.

The base reference used here is the watt per square meter. One kilowatt per square meter is 1,000 base units; one watt per square meter is 1 base units.

Important distinctions

Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.

Common questions

How do I convert kW/m² to W/m²?

Multiply the quantity in kW/m² by 1,000. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the watt per square meter to kilowatt per square meter converter.
