Lead in the blood is measured in which units?

Blood lead levels are very small, so the standard way to report them is in micrograms per deciliter. This unit keeps the numbers in a practical, easy-to-interpret range (for example, values around a few to a few tens of μg/dL are common in exposed individuals) and aligns with public health guidelines and clinical references. If you see a lab using nanograms per milliliter, you can convert it using the fact that 1 μg/dL equals 10 ng/mL. Units like milligrams per deciliter or grams per liter would give values that are far too large for typical blood lead concentrations, making μg/dL the preferred choice.
