the scale is both accurate and precise.
Accurate = close to the 'true' value, and 9.998 is close to 10. Imagine a scale that has the zero point wrong as says 9.998,
it would not be accurate, but still precise (several digits known)
Precise = several digits known.
I would say to know it until grams is quite a good precision (the 9.998 has 4 digits)
