Work out concentration converter instantly with clear inputs, formula shown and shareable results.
Each concentration unit is defined as a multiple of the milligram per litre, so the conversion runs in two steps: multiply by the source unit's factor to reach milligram per litre, then divide by the target unit's factor. One factor per unit covers every pair in the list. For dilute aqueous solutions 1 mg/L equals 1 ppm because a litre of water weighs a kilogram. That equivalence fails for other solvents.
Two-step conversion
result = value × factor(from) ÷ factor(to)
Base value
base (milligram per litre) = value × factor(from)
With 7 units, direct pairs would mean 42 factors to maintain. Going via milligram per litre needs one factor per unit and gives the same answer.
Yes. The first is the unit your figure is already in; the second is what you want it in. Swapping them inverts the result.
