Input Parameters

Calculation Results

Calculation Formula

nM/L = PPB × MW × 1.66 × 10-12

Where:
nM/L = Nanomoles per Liter
PPB = Parts per Billion
MW = Molecular Weight (g/mol)
1.66 × 10-12 = Conversion factor (1 amu = 1.66 × 10-27 kg and 1 mol = 1023 amu)

PPB to Nanomoles per Liter Calculator Usage Guide

Learn how to use the PPB to Nanomoles per Liter Calculator calculator and its working principles

How to Use This Calculator

  1. Enter the concentration value in parts per billion (PPB) in the first input field.
  2. Enter the molecular weight of the substance in grams per mole (g/mol) in the second input field.
  3. Click the "Calculate" button to convert PPB to nanomoles per liter (nM/L).
  4. The result will be displayed in the result field.

Working Principle

This calculator converts concentration from parts per billion (PPB) to nanomoles per liter (nM/L). PPB is a unit of measurement used to express very dilute concentrations, typically in parts per billion by mass or volume.

The conversion formula used is:

nM/L = PPB × MW × 1.66 × 10-12

Where:

  • nM/L = Nanomoles per Liter
  • PPB = Parts per Billion
  • MW = Molecular Weight (g/mol)
  • 1.66 × 10-12 = Conversion factor (1 amu = 1.66 × 10-27 kg and 1 mol = 1023 amu)

Applications

This calculator is useful in various fields including:

  • Environmental science for measuring trace contaminants in water and air
  • Chemistry for preparing dilute solutions
  • Pharmaceuticals for drug concentration calculations
  • Food and beverage testing for trace elements

Example

For example, if you have a contaminant concentration of 50 PPB and the molecular weight of the contaminant is 180 g/mol, the calculation would be:

50 × 180 × 1.66 × 10-12 = 1.494 × 10-9 nM/L = 1.49 nM/L
