How does the precision of measurements affect the precision of scientific calculations?
juin [17]
<span>The precision of scientific calculations is limited by the measurement that's the least precise out of all the measurements used in the calculation. When considering significant figures, the last answer should have the least significant figures out of all the measurements that entered into account and were able to be done with the most significant figures that could be directly measured. So, as more precise we are in measurements, more precise can be the final answer to a scientific calculation.</span>
