A percentage is a pure number: it has no measurement units.
yes, it is. The smaller the measurement, the higher the percentage error.
what is the number supposed to be if you git 7 cm? Percent error is the percentage that you're incorrect by, so you need another measurement. to do it, you find the difference and then divide by the original so (7-x)/true value then multiply by 100 to get percentage.
The answer may depend on why the measurement is changing.
