Yes.
What determines how precise a measurement is
The smaller the measurement, the more accurate.
The smaller the unit the more accurate the measurement will be.
Yes.
An actual measurement is going to be more accurate than an estimate.
The reason you would stir suspension prior to recording the transmittance would be to ensure a distribution that was more equal, thus more accurate. An accurate cell count is important in a number of areas, including medical diagnosis.
For more accurate readings of measurement.

Millimeters are smaller so if a measurement is given in mm it is likely to be more accurate than a measurement given in cm. However, it's important to note that neither mm nor cm is inherently more accurate.
7.50 is a more accurate measurement than 7.5.
Yes.
No. The early systems of measurement were not as accurate as those I use today. The systems of measurement I use today are substantially more accurate than the early systems of bygone days were.
The more accurate number - is 1.005 - as it is accurate to more decimal places than the other examples.

Reading absorbance values is advantageous because it provides a linear relationship with concentration, making it easier to quantify the amount of substance present in a sample. Percent transmittance, on the other hand, is a non-linear measurement that can be affected by factors like stray light, making it less accurate for quantitative analysis.
