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/dm³ = 1,000 mg/m³
1 mg/m³ = 0.001 g/dm³
例子:
将15 克每分立方体转换为每立方米：
15 g/dm³ = 15,000 mg/m³
| 克每分立方体 | 每立方米 |
|---|---|
| 0.01 g/dm³ | 10 mg/m³ |
| 0.1 g/dm³ | 100 mg/m³ |
| 1 g/dm³ | 1,000 mg/m³ |
| 2 g/dm³ | 2,000 mg/m³ |
| 3 g/dm³ | 3,000 mg/m³ |
| 5 g/dm³ | 5,000 mg/m³ |
| 10 g/dm³ | 10,000 mg/m³ |
| 20 g/dm³ | 20,000 mg/m³ |
| 30 g/dm³ | 30,000 mg/m³ |
| 40 g/dm³ | 40,000 mg/m³ |
| 50 g/dm³ | 50,000 mg/m³ |
| 60 g/dm³ | 60,000 mg/m³ |
| 70 g/dm³ | 70,000 mg/m³ |
| 80 g/dm³ | 80,000 mg/m³ |
| 90 g/dm³ | 90,000 mg/m³ |
| 100 g/dm³ | 100,000 mg/m³ |
| 250 g/dm³ | 250,000 mg/m³ |
| 500 g/dm³ | 500,000 mg/m³ |
| 750 g/dm³ | 750,000 mg/m³ |
| 1000 g/dm³ | 1,000,000 mg/m³ |
| 10000 g/dm³ | 10,000,000 mg/m³ |
| 100000 g/dm³ | 100,000,000 mg/m³ |
