250 ppt = 0.25 ppb
Full precision:0.25 ppb
Step-by-Step Solution
To convert 250 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:
250 ÷ 1000 = 0.25 ppb
So 250 ppt = 0.25 ppb.
Quick check: 0.25 × 1000 = 250 ppt
