What is the percent uncertainty for the measurement given as 4.19m?

Answer 1

When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100.

4.19m take the last decimal unit, is 9 but with value of 1/100

.01 is the uncertainty

Now, .01/4.19 x 100 % = 0.24%
