Enter the molar mass in grams per mole (g/mol) and select the solution concentration to determine the equivalent mass concentration in nanograms per microliter (ng/µL).

g/mol to ng/µL Converter

Enter the molar mass and choose the solution concentration to calculate ng/µL.

g/mol
Note: g/mol is a molar mass and ng/µL is a mass-per-volume concentration. To convert between them, you must also know the solution molarity. The relationship is ng/µL = g/mol × mol/L × 1000.

g/mol to ng/µL Formula

The following formula is used to convert a molar mass in grams per mole into a mass concentration in nanograms per microliter for a given solution molarity.

C_{ng/\mu L} = M \times c \times 1000

Variables:

  • Cng/µL is the mass concentration in nanograms per microliter
  • M is the molar mass in grams per mole (g/mol)
  • c is the solution concentration in moles per liter (mol/L)

To calculate the concentration in ng/µL, multiply the molar mass by the solution molarity to get g/L, then multiply by 1000 to convert g/L into ng/µL.

What is g/mol to ng/µL?

Grams per mole (g/mol) describes the molar mass of a compound, while nanograms per microliter (ng/µL) describes how much mass is present in a specific volume of solution. Because these units measure different things, you cannot convert directly from g/mol to ng/µL without also knowing the solution molarity. Once the molarity is known, the conversion becomes straightforward and is commonly used in chemistry, biology, and lab preparation work.

How to Convert g/mol to ng/µL?

The following steps outline how to convert g/mol to ng/µL.


  1. First, determine the molar mass of the compound in g/mol.
  2. Next, determine the solution concentration in mol/L.
  3. Multiply the molar mass by the molarity to calculate the concentration in g/L.
  4. Multiply the result by 1000 to convert g/L into ng/µL.
  5. Check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Molar Mass (M) = 100 g/mol

Solution Concentration (c) = 0.1 mol/L

g/L = 100 × 0.1 = 10 g/L

ng/µL = 10 × 1000 = 10,000 ng/µL

g/mol to ng/µL Conversion Table

The table below lists example mass concentrations in ng/µL for several molar masses and molarities using the formula ng/µL = M × c × 1000.

Molar Mass (g/mol) Molarity (mol/L) Mass Concentration (ng/µL)
50 1 50,000
100 1 100,000
250 1 250,000
50 0.1 5,000
100 0.1 10,000
250 0.01 2,500
100 0.001 100

In practical lab work, this conversion is useful when you know a compound’s molar mass and want to express a solution as ng/µL for pipetting, assay setup, or comparing protocols that use mass-based concentrations.
