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 = 1,000,000 ppb
1 ppb = 1.0000e-6 g/cm³
例子:
将15 克每立方厘米转换为零件十亿：
15 g/cm³ = 15,000,000 ppb
| 克每立方厘米 | 零件十亿 |
|---|---|
| 0.01 g/cm³ | 10,000 ppb |
| 0.1 g/cm³ | 100,000 ppb |
| 1 g/cm³ | 1,000,000 ppb |
| 2 g/cm³ | 2,000,000 ppb |
| 3 g/cm³ | 3,000,000 ppb |
| 5 g/cm³ | 5,000,000 ppb |
| 10 g/cm³ | 10,000,000 ppb |
| 20 g/cm³ | 20,000,000 ppb |
| 30 g/cm³ | 30,000,000 ppb |
| 40 g/cm³ | 40,000,000 ppb |
| 50 g/cm³ | 50,000,000 ppb |
| 60 g/cm³ | 60,000,000 ppb |
| 70 g/cm³ | 70,000,000 ppb |
| 80 g/cm³ | 80,000,000 ppb |
| 90 g/cm³ | 90,000,000 ppb |
| 100 g/cm³ | 100,000,000 ppb |
| 250 g/cm³ | 250,000,000 ppb |
| 500 g/cm³ | 500,000,000 ppb |
| 750 g/cm³ | 750,000,000 ppb |
| 1000 g/cm³ | 1,000,000,000 ppb |
| 10000 g/cm³ | 10,000,000,000 ppb |
| 100000 g/cm³ | 100,000,000,000 ppb |
