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 g/m³ = 1,000,000 µg/L
1 µg/L = 1.0000e-6 g/m³
例子:
将15 克每立方米转换为微克每升：
15 g/m³ = 15,000,000 µg/L
| 克每立方米 | 微克每升 |
|---|---|
| 0.01 g/m³ | 10,000 µg/L |
| 0.1 g/m³ | 100,000 µg/L |
| 1 g/m³ | 1,000,000 µg/L |
| 2 g/m³ | 2,000,000 µg/L |
| 3 g/m³ | 3,000,000 µg/L |
| 5 g/m³ | 5,000,000 µg/L |
| 10 g/m³ | 10,000,000 µg/L |
| 20 g/m³ | 20,000,000 µg/L |
| 30 g/m³ | 30,000,000 µg/L |
| 40 g/m³ | 40,000,000 µg/L |
| 50 g/m³ | 50,000,000 µg/L |
| 60 g/m³ | 60,000,000 µg/L |
| 70 g/m³ | 70,000,000 µg/L |
| 80 g/m³ | 80,000,000 µg/L |
| 90 g/m³ | 90,000,000 µg/L |
| 100 g/m³ | 100,000,000 µg/L |
| 250 g/m³ | 250,000,000 µg/L |
| 500 g/m³ | 500,000,000 µg/L |
| 750 g/m³ | 750,000,000 µg/L |
| 1000 g/m³ | 1,000,000,000 µg/L |
| 10000 g/m³ | 10,000,000,000 µg/L |
| 100000 g/m³ | 100,000,000,000 µg/L |
