In summary, "8 parts in 1010" is a ratio or proportion that represents 8 parts out of a total of 1010 parts. Its significance depends on the context and can be used to indicate both small and large amounts. This measurement is often used in scientific contexts due to its convenience in expressing very small or large numbers. It is also related to high levels of precision and accuracy in scientific measurements. "8 parts in 1010" can be converted to a decimal or percentage, such as 0.0000000008 or 0.00000008%, and is equivalent to 8 parts per billion.

Trying to answer a question that state an experiment results shows uncertainty of 8 parts in 10¹⁰.
Can anyone shed some light on the meaning. I don't understand.
Thank you
