Percentages can be confusing, especially in reference to per mills and per million. Parts per million calculations are used to measure small concentrations in a solution, solid and gas or the number of defects in manufacturing. PPM, part per million, is just a way of referring to very small concentrations of substances, usually in water or soil. Which makes it a popular calculation for agricultural, water treatment industries, and chemists.
PPM to % Converter
The basic formula for PPM begins by dividing the weight or number of defects by volume and then multiplying the result by 1,000,000.
