Type a value in kW/m² to get it in W/m² instantly.

1,000,000W/m²

That's 735× as bright as sunlight above the atmosphere — nothing on our list beats it. A two-square-meter panel at 20% would make about 400,000 W.

What it means

How much sun is that?

Panels are rated at 1,000 W/m², called one sun. kWh/m² per day here is averaged over 24 hours, not over daylight only.

The math

How to convert kW/m² to W/m²

To convert kilowatts per square meter to watts per square meter, multiply by 1,000.

Example: 1,000 kW/m² × 1,000 = 1,000,000 W/m².

In the other direction, 1 W/m² = 0.001 kW/m².
