4 ppb = 4e-6 ‰
Full precision:0.000004 ‰
Step-by-Step Solution
To convert 4 ppb to per mille, we divide by 1000000 because one per mille equals exactly 1000000 ppb.
1 per mille = 1000000 ppb
Since there are 1000000 ppb in every per mille, we divide our value by this factor:
4 ÷ 1000000 = 4e-6 per mille
So 4 ppb = 4e-6 per mille.
Quick check: 4e-6 × 1000000 = 4 ppb
