# ppm / ppb / percent CONVERTER

## Introduction

To convert between units just type the know value. It will converted automatically to the other units. This tool can be used for the following convertions:
路 Percent (%) to ppm
路 ppm to percent (%)
路 ppm to ppb
路 ppb to ppm
路 Percent to ppb
路 ppb to percent

# PPM / PERCENT. Concentration converter

Enter the known value:
 ppm ppb %

1ppm = 1000 ppb
1%     = 10000 ppm
1%     = 10000000 ppb

## Definitions

### ppm (parts per million)

One part per million is one part of solute per one million parts of solvent. It is a dimensionless unit. The equivalency between ppm and % (percent) is as follows:

1 ppm = 0,0001%
10.000 ppm = 1%

As water density is 1 kg/m3 (This is the value normally considered although it varies slightly with temperature, you can calculate it with accuracy with our water density calculator), one ppm is equivalent to 1 milligram of something per liter of water (mg/l). In general it is equivalent to 1 mg/kg.

### ppb (parts per billion)

One part per bilion is one part of solute per one billion parts of solvet.
1000 ppb = 1ppm = 0.0001%
1 ppb = 0.001ppm = 0.0000001%
