1 ppb = 1e-7 %
Full precision:1e-7 %
Step-by-Step Solution
To convert 1 ppb to percent, we divide by 10000000 because one percent equals exactly 10000000 ppb.
1 percent = 10000000 ppb
Since there are 10000000 ppb in every percent, we divide our value by this factor:
1 ÷ 10000000 = 1e-7 percent
So 1 ppb = 1e-7 percent.
Quick check: 1e-7 × 10000000 = 1 ppb
Example Conversions
Example 1: 1 ppb = 1e-7 %
1 ÷ 10000000 = 1e-7
1 ÷ 10000000 = 1e-7
Example 2: 5 ppb = 5e-7 %
5 ÷ 10000000 = 5e-7
5 ÷ 10000000 = 5e-7
Example 3: 10 ppb = 1e-6 %
10 ÷ 10000000 = 1e-6
10 ÷ 10000000 = 1e-6
