Final answer:
When scientists don't have a standard system of measurement, it can create confusion and inconsistencies in their work. Having a standard system, like the metric system, ensures consistency and easy comparison of scientific data.
Step-by-step explanation:
When scientists don't have a standard system of measurement for the scientific community, it can create confusion and make it difficult to communicate and compare results. Without a standard system, scientists may use different units or measurements, which can lead to inconsistencies and errors in their work. For example, if one scientist measures length in inches while another scientist measures in centimeters, it would be challenging to compare their data accurately. Having a standard system of measurement, such as the metric system, ensures that scientists are using consistent units and allows for easy comparison and understanding of scientific data.
