如何将以百万分率 (ppm)为单位的数字转换为百分比 (%)。
1% = 1/100
1ppm = 1/10000
2% = 2/200
2ppm = 2/20000
所以百万分之一等于 0.0001%:
1ppm = 0.0001%
因此,要将 ppm 转换为百分比,请将 ppm 除以 10000:
x(%) = x(ppm) / 10000
将 100ppm 转换为百分比:
x(%) = 100ppm / 10000 = 0.01%
将 200ppm 转换为百分比:
x(%) = 200ppm / 10000 = 0.02%
将 400ppm 转换为百分比:
x(%) = 400ppm / 10000 = 0.04%
将 600ppm 转换为百分比:
x(%) = 600ppm / 10000 = 0.06%
将 800ppm 转换为百分比:
x(%) = 800ppm / 10000 = 0.08%
将 900ppm 转换为百分比:
x(%) = 900ppm / 10000 = 0.09%
将 19000ppm 转换为百分比:
x(%) = 19000ppm / 10000 = 1.9%
