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 mol/cm³ = 1,000 ppb
1 ppb = 0.001 mol/cm³
例子:
将15 每立方厘米的痣转换为零件十亿：
15 mol/cm³ = 15,000 ppb
| 每立方厘米的痣 | 零件十亿 |
|---|---|
| 0.01 mol/cm³ | 10 ppb |
| 0.1 mol/cm³ | 100 ppb |
| 1 mol/cm³ | 1,000 ppb |
| 2 mol/cm³ | 2,000 ppb |
| 3 mol/cm³ | 3,000 ppb |
| 5 mol/cm³ | 5,000 ppb |
| 10 mol/cm³ | 10,000 ppb |
| 20 mol/cm³ | 20,000 ppb |
| 30 mol/cm³ | 30,000 ppb |
| 40 mol/cm³ | 40,000 ppb |
| 50 mol/cm³ | 50,000 ppb |
| 60 mol/cm³ | 60,000 ppb |
| 70 mol/cm³ | 70,000 ppb |
| 80 mol/cm³ | 80,000 ppb |
| 90 mol/cm³ | 90,000 ppb |
| 100 mol/cm³ | 100,000 ppb |
| 250 mol/cm³ | 250,000 ppb |
| 500 mol/cm³ | 500,000 ppb |
| 750 mol/cm³ | 750,000 ppb |
| 1000 mol/cm³ | 1,000,000 ppb |
| 10000 mol/cm³ | 10,000,000 ppb |
| 100000 mol/cm³ | 100,000,000 ppb |
