How does conversion of units from metric to English system affect the level of accuracy of a certain measure?

Answer 1

When done correctly, conversion of units will have no effect on the level of accuracy of a particular measurement. However, there are times when the converted measure is rounded to a whole or half unit in the new system of measure, and in those cases the accuracy of the measurement is reduces.

Answer 2

The accuracy of measurement does not depend on the system. A length can be measured in inches or thousandths of inches or millionths of inches. Similarly, it can be measured in metres or millimetres (thousandths) or micrometres (millionths) etc. Having names for these smaller measurement units does not affect the accuracy in any way whatsoever.

Answer 3

There is nothing inherent to a system of units that causes measurements expressed in it to be

any more or less accurate than measurements expressed in any other system.

If there were, then all less-accurate systems would have been discarded long ago, and the

people, business, and technology of the world would all be using the same, more-accurate

system.

Any measurement can be expressed in any system of units, and can be converted from one system

to another long after the measurement is made. If its accuracy is affected by the conversion, then

the cause lies with the the process and factors used to convert.

Answer 4

Converting units between metric and English systems does not affect the level of accuracy of the measured quantity itself; the accuracy remains the same. However, rounding errors or inaccuracies can occur during the conversion process, which may affect the final reported value if not done carefully.
