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

1 ppt = 0.001 ppb
Full precision:0.001 ppb
Step-by-Step Solution
To convert 1 ppt to ppb, we divide by 1000 because one parts per billion equals exactly 1000 ppt.
1 parts per billion = 1000 ppt
Since there are 1000 ppt in every parts per billion, we divide our value by this factor:
1 ÷ 1000 = 0.001 ppb
So 1 ppt = 0.001 ppb.
Quick check: 0.001 × 1000 = 1 ppt
Example Conversions
Example 1: 1 ppt = 0.001 ppb
1 ÷ 1000 = 0.001
1 ÷ 1000 = 0.001
Example 2: 5 ppt = 0.005 ppb
5 ÷ 1000 = 0.005
5 ÷ 1000 = 0.005
Example 3: 10 ppt = 0.01 ppb
10 ÷ 1000 = 0.01
10 ÷ 1000 = 0.01
