1 ppm = 0.0001 %
Full precision:0.0001 %
Step-by-Step Solution
To convert 1 ppm to percent, we divide by 10000 because one percent equals exactly 10000 ppm.
1 percent = 10000 ppm
Since there are 10000 ppm in every percent, we divide our value by this factor:
1 ÷ 10000 = 0.0001 percent
So 1 ppm = 0.0001 percent.
Quick check: 0.0001 × 10000 = 1 ppm
Example Conversions
Example 1: 1 ppm = 0.0001 %
1 ÷ 10000 = 0.0001
1 ÷ 10000 = 0.0001
Example 2: 5 ppm = 0.0005 %
5 ÷ 10000 = 0.0005
5 ÷ 10000 = 0.0005
Example 3: 10 ppm = 0.001 %
10 ÷ 10000 = 0.001
10 ÷ 10000 = 0.001
