How to convert watts per square meter to watts per square centimeter
Heat flux density is power per area, W/m². A positive or negative sign can indicate direction under the chosen sign convention; this tool preserves that sign.
Use x for the value in W/m², b for the intermediate value in W/m², and y for the result in W/cm².
W/cm² = W/m² ÷ 10000
Worked examples
10 W/m² ≈ 0.001 W/cm²
Step 1: (10 × 1) ≈ 10 W/m².
Step 2: 10 ÷ 10000 ≈ 0.001 W/cm².20 W/m² ≈ 0.002 W/cm²
Step 1: (20 × 1) ≈ 20 W/m².
Step 2: 20 ÷ 10000 ≈ 0.002 W/cm².
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Watts per square meter
Watts per square meter (W/m²) measures heat flux density under the conventions above. The base value in W/m² is (x × 1), where x is the numerical value in W/m². Factors shown here are rounded for display; calculations use the stored factor.
About Watts per square centimeter
Watts per square centimeter (W/cm²) measures heat flux density under the conventions above. The base value in W/m² is (x × 10000), where x is the numerical value in W/cm². Factors shown here are rounded for display; calculations use the stored factor.
