watt per square inch to watt per square centimeter
Convert watt per square inch (W/in²) to watt per square centimeter (W/cm²). Use an editable heat flux converter, conversion formula, and reference table.
1 W/in² = 0.15500031 W/cm²
Conversion formula
One watt per square inch equals 0.15500031 watt per square centimeter. Multiply your value in watt per square inch by this factor to get watt per square centimeter. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 watt per square inch:5 × 0.15500031 = 0.77500155 W/cm²

About these measurements
Heat flux is thermal power per unit surface area.
The base reference used here is the watt per square meter. One watt per square inch is 1,550.0031 base units; one watt per square centimeter is 10,000 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 W/in² to W/cm²?
Multiply the quantity in W/in² by 0.15500031. 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 centimeter to watt per square inch converter.
