1 ng/dL = 0.0154 nmol/L. Nothing you type here leaves your browser.
The conversion
- 1 ng/dL = 0.01536 nmol/LFrom ng/dL to nmol/L: divide by 65.1. Back again: multiply by 65.1.
- 1 ng/dL = 15.36 pmol/LFrom ng/dL to pmol/L: multiply by 15.36. Back again: divide by 15.36.
- 1 ng/dL = 10 pg/mLFrom ng/dL to pg/mL: multiply by 10. Back again: divide by 10.
pg/mL and ng/L give the same number.
Mass and molar units are linked by the molecular weight: 650.97 g/mol (reverse T3 (3,3',5'-triiodo-L-thyronine), C15H12I3NO4). Source: PubChem (NIH National Library of Medicine).
Common values
From zero to about twice the usual upper limit, plus the usual limits themselves.
