1 ng/dL = 0.0347 nmol/L. Nothing you type here leaves your browser.
The conversion
- 1 ng/dL = 0.03467 nmol/LFrom ng/dL to nmol/L: divide by 28.84. Back again: multiply by 28.84.
- 1 ng/dL = 0.01 ng/mLFrom ng/dL to ng/mL: divide by 100. Back again: multiply by 100.
- 1 ng/dL = 10 pg/mLFrom ng/dL to pg/mL: multiply by 10. Back again: divide by 10.
