浓度(摩尔)是每升溶液的摩尔数量的度量,通常以每升摩尔(mol/l)测量。
1 ppm = 1.0000e-4 %mass
1 %mass = 10,000 ppm
例子:
将15 零件百万转换为质量百分比:
15 ppm = 0.001 %mass
| 零件百万 | 质量百分比 |
|---|---|
| 0.01 ppm | 1.0000e-6 %mass |
| 0.1 ppm | 1.0000e-5 %mass |
| 1 ppm | 1.0000e-4 %mass |
| 2 ppm | 0 %mass |
| 3 ppm | 0 %mass |
| 5 ppm | 0.001 %mass |
| 10 ppm | 0.001 %mass |
| 20 ppm | 0.002 %mass |
| 30 ppm | 0.003 %mass |
| 40 ppm | 0.004 %mass |
| 50 ppm | 0.005 %mass |
| 60 ppm | 0.006 %mass |
| 70 ppm | 0.007 %mass |
| 80 ppm | 0.008 %mass |
| 90 ppm | 0.009 %mass |
| 100 ppm | 0.01 %mass |
| 250 ppm | 0.025 %mass |
| 500 ppm | 0.05 %mass |
| 750 ppm | 0.075 %mass |
| 1000 ppm | 0.1 %mass |
| 10000 ppm | 1 %mass |
| 100000 ppm | 10 %mass |
