Kilogram square meter quick reference
| Kilogram square meter | Pound square foot | Kilogram square centimeter | Gram square centimeter |
|---|---|---|---|
| 1 kg·m² | ≈ 23.7303604 lb·ft² | = 10000 kg·cm² | = 10000000 g·cm² |
| 10 kg·m² | ≈ 237.303604 lb·ft² | = 100000 kg·cm² | = 100000000 g·cm² |
| 100 kg·m² | ≈ 2373.03604 lb·ft² | = 1000000 kg·cm² | = 1000000000 g·cm² |
| 1000 kg·m² | ≈ 23730.3604 lb·ft² | = 10000000 kg·cm² | = 10000000000 g·cm² |
