How to Convert mW/cm² to W/m²

To convert milliwatts per square centimeter (mW/cm²) to watts per square meter (W/m²), follow these steps:

Step 1: Understand the unit conversion factors

• 1 mW = 0.001 W
• 1 cm² = 0.0001 m²

Step 2: Derive the conversion formula

Since we’re converting mW/cm² to W/m², we need to:

1. Convert mW to W by multiplying by 0.001
2. Convert cm² to m² by dividing by 0.0001

This gives us: mW/cm² × (0.001 W/mW) × (1/0.0001 m²/cm²) = mW/cm² × 10

Therefore, to convert from mW/cm² to W/m², multiply the value by 10.

Examples:

• 10 mW/cm² = 10 × 10 = 100 W/m²
• 1 mW/cm² = 1 × 10 = 10 W/m²
• 5 mW/cm² = 5 × 10 = 50 W/m²
• 0.2 mW/cm² = 0.2 × 10 = 2 W/m²
