How to use this density converter
Enter density in any unit and see it in all others. The quick buttons show common 3D printing filaments: ABS at 1.04 g/cm³, PLA at 1.24 g/cm³, PETG at 1.27 g/cm³, and aluminum at 2.7 g/cm³ for reference. Use this when comparing materials, calculating shipping weights, or understanding material datasheets.
Common material density reference
| Material | g/cm³ | kg/m³ | lb/ft³ |
|---|---|---|---|
| Water (reference) | 1.00 | 1000 | 62.4 |
| ABS filament | 1.04 | 1040 | 64.9 |
| ASA filament | 1.07 | 1070 | 66.8 |
| TPU filament | 1.21 | 1210 | 75.5 |
| PLA filament | 1.24 | 1240 | 77.4 |
| PETG filament | 1.27 | 1270 | 79.3 |
| Standard resin | 1.15-1.20 | 1150-1200 | 71.8-74.9 |
| Aluminum | 2.70 | 2700 | 168.6 |
| Steel | 7.85 | 7850 | 490.1 |
When you need this tool
Your filament calculator needs density in g/cm³ but the datasheet lists kg/m³. Or you're comparing resin types where one manufacturer uses lb/ft³ and another uses g/cm³. Or you're estimating shipping weights for bulk material orders. Just convert the units here.
