浓度（质量）是指组成部分的质量除以混合物的总体积。它通常以每立方米（kg/m³）公斤（千克）进行测量。
1 kg/m³ = 1,000,000,000 µg/L
1 µg/L = 1.0000e-9 kg/m³
例子:
将15 每立方米转换为微克每升：
15 kg/m³ = 15,000,000,000 µg/L
| 每立方米 | 微克每升 |
|---|---|
| 0.01 kg/m³ | 10,000,000 µg/L |
| 0.1 kg/m³ | 100,000,000 µg/L |
| 1 kg/m³ | 1,000,000,000 µg/L |
| 2 kg/m³ | 2,000,000,000 µg/L |
| 3 kg/m³ | 3,000,000,000 µg/L |
| 5 kg/m³ | 5,000,000,000 µg/L |
| 10 kg/m³ | 10,000,000,000 µg/L |
| 20 kg/m³ | 20,000,000,000 µg/L |
| 30 kg/m³ | 30,000,000,000 µg/L |
| 40 kg/m³ | 40,000,000,000 µg/L |
| 50 kg/m³ | 50,000,000,000 µg/L |

| 750 kg/m³ | 750,000,000,000 µg/L |
| 1000 kg/m³ | 1,000,000,000,000 µg/L |
| 10000 kg/m³ | 9,999,999,999,999.998 µg/L |
| 100000 kg/m³ | 99,999,999,999,999.98 µg/L |
