浓度（摩尔）是每升溶液的摩尔数量的度量，通常以每升摩尔（mol/l）测量。
1 g/cm³ = 1,000 ppm
1 ppm = 0.001 g/cm³
例子:
将15 克每立方厘米转换为零件百万：
15 g/cm³ = 15,000 ppm
| 克每立方厘米 | 零件百万 |
|---|---|
| 0.01 g/cm³ | 10 ppm |
| 0.1 g/cm³ | 100 ppm |
| 1 g/cm³ | 1,000 ppm |
| 2 g/cm³ | 2,000 ppm |
| 3 g/cm³ | 3,000 ppm |
| 5 g/cm³ | 5,000 ppm |
| 10 g/cm³ | 10,000 ppm |
| 20 g/cm³ | 20,000 ppm |
| 30 g/cm³ | 30,000 ppm |
| 40 g/cm³ | 40,000 ppm |
| 50 g/cm³ | 50,000 ppm |
| 60 g/cm³ | 60,000 ppm |
| 70 g/cm³ | 70,000 ppm |
| 80 g/cm³ | 80,000 ppm |
| 90 g/cm³ | 90,000 ppm |
| 100 g/cm³ | 100,000 ppm |
| 250 g/cm³ | 250,000 ppm |
| 500 g/cm³ | 500,000 ppm |
| 750 g/cm³ | 750,000 ppm |
| 1000 g/cm³ | 1,000,000 ppm |
| 10000 g/cm³ | 10,000,000 ppm |
| 100000 g/cm³ | 100,000,000 ppm |
