A nonilion is a number with 30 digits.
significant thank you very much
Your measurement should include one estimated digit.
The quantity of matter in an object is its mass. If you then know what the object is made from you can find out (approximately) how many atoms or molecules it has (measured in mol).
The rules for significant figures help convey the precision of measured and calculated values by indicating how many digits are considered reliable. When reporting measurements, only the digits that are known with certainty, plus one estimated digit, are included as significant figures. In calculations, the result should be expressed with the same number of significant figures as the measurement with the least precision, reflecting the inherent uncertainty. This practice ensures that the reported values accurately represent the degree of confidence in the measurements.
The weight of an object is the force exerted on it due to gravity, typically measured in units like pounds or kilograms. It is different from mass, which is the amount of matter in an object and is typically measured in units like grams or kilograms.

matter is not measured by grams or kilograms. that is mass. but matter is measured by using mass. mass is the amount of matter in an object.
6 digits
It means that only an idea of an object is exactly whatever value a measurement gives. There are so many more never ending decimal numbers like pi than there are decimals of finite length like 0.5 that there is a zero chance that the object which was measured to be 0.5 units is actually that value. However far you zoom in, there is always room to improve the observation by zooming in more.
