percent error
The relative error measurements indicates the quality of a measurement relative to the quantity of the object being measured. To derive the relative error, divide the absolute error by the value of the object being measured.
The ratio of an error to an accepted value is called the relative error. It is a measure of how large the error is compared to the accepted value. By expressing the error relative to the accepted value, it allows for a standardized comparison between different measurements or experiments.
The relative error depends on the true value of the measurement. That information has not been provided.
To get the relative error is the maximum error over the measurement. So the maximum error is the absolute error divided by 2. So the maximum error is 0.45. The relative error is 0.45 over 45 cm.
Percent error.
The error bound is half of the last digit = ±0.0005 The relative error is ±0.000145 or ±0.0145%

The formula for relative error is:Erel= |x-x*| / |x|, where x is the proper value, and x* an approximate value.
