Full precision:0.25 ppb
Step-by-Step Solution
To convert 0.00025 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:
0.00025 × 1000 = 0.25 ppb
So 0.00025 ppm = 0.25 ppb.
Quick check: 0.25 ÷ 1000 = 0.00025 ppm
