1% = 10000 ppm

1% = 10000000 ppb

1 ppm = 0,0001%

10.000 ppm = 1%

As water density is 1 kg/m3 (This is the value normally considered although it varies slightly with temperature, you can calculate it with accuracy with our water density calculator), one ppm is equivalent to 1 milligram of something per liter of water (mg/l). In general it is equivalent to 1 mg/kg.

1000 ppb = 1ppm = 0.0001%

1 ppb = 0.001ppm = 0.0000001%
