How to Convert UG to PPM
- 1). Recognize that 1 mg/l equals 1 ppm and 1,000 ug equal 1 mg. You must identify the conversion factors that will allow you to convert between these two unit systems.
- 2). Divide the concentration of the original solution by 1,000 to obtain the concentration units of mg/l. For example, convert 14.7 ug/l solution to mg/l. 14.7 / 1000 = 0.0147 mg/l.
- 3). Change the units of concentration from mg/l to ppm based on the conversion of 1 mg/l equals 1 ppm. Continuing the example, 0.0147 mg/l = 0.0147 ppm.
