Gram square centimeter quick reference
| Gram square centimeter | Kilogram square meter | Pound square foot | Kilogram square centimeter |
|---|---|---|---|
| 1 g·cm² | = 1e-7 kg·m² | ≈ 0.00000237303604 lb·ft² | = 0.001 kg·cm² |
| 10 g·cm² | = 0.000001 kg·m² | ≈ 0.0000237303604 lb·ft² | = 0.01 kg·cm² |
| 100 g·cm² | = 0.00001 kg·m² | ≈ 0.000237303604 lb·ft² | = 0.1 kg·cm² |
| 1000 g·cm² | = 0.0001 kg·m² | ≈ 0.00237303604 lb·ft² | = 1 kg·cm² |
