Kilowatt-hour per square meter quick reference
| Kilowatt-hour per square meter | Megajoule per square meter | Kilojoule per square meter | BTU per square foot |
|---|---|---|---|
| 1 kWh/m² | = 3.6 MJ/m² | = 3600 kJ/m² | ≈ 316.9983306 BTU/ft² |
| 10 kWh/m² | = 36 MJ/m² | = 36000 kJ/m² | ≈ 3169.983306 BTU/ft² |
| 100 kWh/m² | = 360 MJ/m² | = 360000 kJ/m² | ≈ 31699.83306 BTU/ft² |
| 1000 kWh/m² | = 3600 MJ/m² | = 3600000 kJ/m² | ≈ 316998.3306 BTU/ft² |
Where the kilowatt-hour per square meter fits
The next smaller heat density unit is the megajoule per square meter (MJ/m²). 1 kWh/m² = 3.6 MJ/m², and 1 MJ/m² ≈ 0.2777777778 kWh/m².
