2. Select Units: Choose your current unit (e.g., PPM) and target unit (e.g., PPB).
3. Get Result: Click "Convert Concentration" for the immediate equivalent.

Frequently Asked Questions

What is the difference between parts per million and parts per billion?

The difference is magnitude. One PPM is 1,000 times larger than one PPB. Think of it as seconds: 1 PPM is roughly 32 seconds in a year, while 1 PPB is roughly 3 seconds in a century.

What is 1 ppb equal to?

1 PPB equals 0.001 PPM. In water quality analysis, this is generally equivalent to 1 microgram per liter (µg/L).

How to convert parts into percentage?

To convert Parts Per Million (PPM) to a percentage, divide the PPM value by 10,000. For example, 500 PPM ÷ 10,000 = 0.05%.

What does 10 parts per billion mean?

It indicates a ratio of 10 units of substance per one billion units of total solution. In solid mixtures, this is equivalent to 10 micrograms per kilogram.

What percent is 100 parts per million?

100 PPM equals exactly 0.01%. This is a common conversion used when switching between trace analysis and general composition percentages.
