How the milligram per liter to part per million (in water) conversion works
For dilute water solutions 1 mg/L and 1 ppm are the same number.
Multiply by 1 to go from milligram per liter to part per million (in water):
ppm = mg/L × 1
Going the other way, multiply by 1, which is the same as dividing by 1.
