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/mL = 0.1 %mass
1 %mass = 10 g/mL
例子:
将15 Grams per Milliliter转换为质量百分比：
15 g/mL = 1.5 %mass
| Grams per Milliliter | 质量百分比 |
|---|---|
| 0.01 g/mL | 0.001 %mass |
| 0.1 g/mL | 0.01 %mass |
| 1 g/mL | 0.1 %mass |
| 2 g/mL | 0.2 %mass |
| 3 g/mL | 0.3 %mass |
| 5 g/mL | 0.5 %mass |
| 10 g/mL | 1 %mass |
| 20 g/mL | 2 %mass |
| 30 g/mL | 3 %mass |
| 40 g/mL | 4 %mass |
| 50 g/mL | 5 %mass |
| 60 g/mL | 6 %mass |
| 70 g/mL | 7 %mass |
| 80 g/mL | 8 %mass |
| 90 g/mL | 9 %mass |
| 100 g/mL | 10 %mass |
| 250 g/mL | 25 %mass |
| 500 g/mL | 50 %mass |
| 750 g/mL | 75 %mass |
| 1000 g/mL | 100 %mass |
| 10000 g/mL | 1,000 %mass |
| 100000 g/mL | 10,000 %mass |
