4 ppb = 0.004 ppm
Full precision:0.004 ppm
Step-by-Step Solution
To convert 4 ppb to ppm, we divide by 1000 because one parts per million equals exactly 1000 ppb.
1 parts per million = 1000 ppb
Since there are 1000 ppb in every parts per million, we divide our value by this factor:
4 ÷ 1000 = 0.004 ppm
So 4 ppb = 0.004 ppm.
Quick check: 0.004 × 1000 = 4 ppb
