Not only will this be confusing to the medical professional giving the dose, but the consequences can be dire: 100 mg given three times per day can be effective as an anticonvulsant, but a single dose of 100 g is more than 10 times the lethal amount.

The International System of Units is a system of measurement based on the metric system and has been adopted by scientists as their official system of measurement.
