ug/kg, ug/L to ppm
Does 1,000 ug/kg = 1 ppm? How many parts ppm is 1,800 ug/L?
Does 1,800 ug/L = 1.8ppm? Thank You!

Re: ug/kg, ug/L to ppm
ppm stands for parts per million. There is 1000g in a kg, 1,000,000mg in a kg, and 1,000,000,000ug in a kg.
1000ug/kg is therefore 1ppm 1800ug/L is 1.8ppm. If you are talking about volumes, 1000mL = 1L, 1,000,000uL = 1L, so 1uL/L = 1ppm.  this is particularly important with gases.

Thanks! So does 53,000 ug/kg = 53ppm? Is water 1,800 ug/L = 1.8 ppm? Very Appreciative

For problems such as this, you can always relate it to what "100%" MEANS. A pure substance is 1,000,000ppm.

Parts per million (or billion) can also be ratios of volumes or moles.
