As a healthcare professional, what are the possible consequences for failing to master metric system conversion skills

It can create confusion with English system or SI system leading to fatal consequences

Step-by-step explanation:

A healthcare professional might have studied the SI system in his college studies and he might be using metric system in hospital. This sort of errors may lead to fatal results for example if a weight machine records weight in kg and the healthcare professional is more familiar with pounds then it can produce big mistakes because he might take weight into pounds and lead to death of patient. For example, a weight may be entered into electronic health record as 35 kilograms (the equivalent of 77 pounds) rather than the actual weight of 35 pounds so it can cause serious issues.

You could cause your patience to overdose on the drugs you proscribe to them and even worth, death.
