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/L = 0.1 %wt
1 %wt = 10 g/L
例子:
将15 克每升转换为重量百分比：
15 g/L = 1.5 %wt
| 克每升 | 重量百分比 |
|---|---|
| 0.01 g/L | 0.001 %wt |
| 0.1 g/L | 0.01 %wt |
| 1 g/L | 0.1 %wt |
| 2 g/L | 0.2 %wt |
| 3 g/L | 0.3 %wt |
| 5 g/L | 0.5 %wt |
| 10 g/L | 1 %wt |
| 20 g/L | 2 %wt |
| 30 g/L | 3 %wt |
| 40 g/L | 4 %wt |
| 50 g/L | 5 %wt |
| 60 g/L | 6 %wt |
| 70 g/L | 7 %wt |
| 80 g/L | 8 %wt |
| 90 g/L | 9 %wt |
| 100 g/L | 10 %wt |
| 250 g/L | 25 %wt |
| 500 g/L | 50 %wt |
| 750 g/L | 75 %wt |
| 1000 g/L | 100 %wt |
| 10000 g/L | 1,000 %wt |
| 100000 g/L | 10,000 %wt |
