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/m³ = 1,000 ppm
1 ppm = 0.001 mol/m³
例子:
将15 每立方米的痣转换为零件百万：
15 mol/m³ = 15,000 ppm
| 每立方米的痣 | 零件百万 |
|---|---|
| 0.01 mol/m³ | 10 ppm |
| 0.1 mol/m³ | 100 ppm |
| 1 mol/m³ | 1,000 ppm |
| 2 mol/m³ | 2,000 ppm |
| 3 mol/m³ | 3,000 ppm |
| 5 mol/m³ | 5,000 ppm |
| 10 mol/m³ | 10,000 ppm |
| 20 mol/m³ | 20,000 ppm |
| 30 mol/m³ | 30,000 ppm |
| 40 mol/m³ | 40,000 ppm |
| 50 mol/m³ | 50,000 ppm |
| 60 mol/m³ | 60,000 ppm |
| 70 mol/m³ | 70,000 ppm |
| 80 mol/m³ | 80,000 ppm |
| 90 mol/m³ | 90,000 ppm |
| 100 mol/m³ | 100,000 ppm |
| 250 mol/m³ | 250,000 ppm |
| 500 mol/m³ | 500,000 ppm |
| 750 mol/m³ | 750,000 ppm |
| 1000 mol/m³ | 1,000,000 ppm |
| 10000 mol/m³ | 10,000,000 ppm |
| 100000 mol/m³ | 100,000,000 ppm |
