Converting nmol/l to ppm Mercury

I have a blood reading of 27.3 nmol/l for Mercury.
How do I convert this to ppm?
Everything on the web refers to ppm in terms of toxicity, this is why I want to convert.

Look up atomic weight of mercury, which is also the number of grams per mole. If you multiply it by nanomoles, you get nanograms.

I don't know how much a liter of blood weighs, it must be close to, but slightly greater than 1 kg.

ng/kg would give parts per trillon as they are 10^12 apart, but your number may be large enough to move decimal and adjust. I think you are talking parts per billion, but I didn't do the math.
