How to Convert ppm to ppb
To convert ppm to ppb, multiply the value by 1000.
The Formula
ppb = ppm × 1000
Key Fact
1 parts per million = 1000 ppb
Tip: To convert ppb back to ppm, divide by 1000.

Full precision:1000 ppb
Step-by-Step Solution
To convert 1 ppm to ppb, we multiply by 1000 because one parts per million equals exactly 1000 ppb.
1 parts per million = 1000 ppb
Since each parts per million contains 1000 ppb, we multiply our value by this factor:
1 × 1000 = 1000 ppb
So 1 ppm = 1000 ppb.
Quick check: 1000 ÷ 1000 = 1 ppm
Example Conversions
Example 1: 1 ppm = 1000 ppb
1 × 1000 = 1000
1 × 1000 = 1000
Example 2: 5 ppm = 5000 ppb
5 × 1000 = 5000
5 × 1000 = 5000
Example 3: 10 ppm = 10000 ppb
10 × 1000 = 10000
10 × 1000 = 10000
