pg/ml to ng/ml Converter

Convert pg/mL to ng/mL by dividing by 1,000, or ng/mL to pg/mL, with ng/L, ng/dL and µg/mL equivalents for troponin and other lab results.

Calculator Functions

Function	What it does	What it requires
pg/mL to ng/mL	Converts picograms per milliliter to nanograms per milliliter	Requires a concentration in pg/mL
ng/mL to pg/mL	Converts nanograms per milliliter to picograms per milliliter	Requires a concentration in ng/mL

Each result also shows the same concentration in µg/mL, ng/dL, µg/dL and ng/L. Decimal places can be left on Auto or set to 2, 3, 4 or 6.

pg/mL to ng/mL Formulas

The prefix nano means 10⁻⁹ and pico means 10⁻¹² [1], so one nanogram is 1,000 picograms. Both units are per milliliter, so only the mass part changes. The factor is the same for every substance: a troponin, hormone or vitamin result of 14 pg/mL is 0.014 ng/mL.

pg/mL to ng/mL

The main formula applies directly. 2,500 pg/mL is 2.5 ng/mL, and 30,000 pg/mL is 30 ng/mL.

ng/mL to pg/mL

0.04 ng/mL is 40 pg/mL, and 2.5 ng/mL is 2,500 pg/mL.

pg/mL to ng/L and ng/dL

pg/mL and ng/L are the same number. A liter is 1,000 milliliters [2] and a nanogram is 1,000 picograms, so the two factors cancel: 14 pg/mL is 14 ng/L. A deciliter is 100 mL, so ng/dL is the pg/mL value divided by 10. The result also gives µg/dL (divide by 10,000) and µg/mL (divide by 1,000,000).

Limits of This Estimate

• This is unit arithmetic only. It says nothing about whether a lab value is normal, and reference ranges differ between tests and laboratories.
• It converts between mass units. Results reported in pmol/L, nmol/L or IU need the substance’s molar mass or unit definition and cannot be converted here.
• Display rounding follows the decimal places setting. Very small or very large values are shown in scientific notation so that a nonzero value never displays as zero.
