Step-by-step explanation:
When we use the metric system we have more security of everything that we are doing. For example: In health when you go to the doctor and he prescribes you some medicine you have to take the exact amount of each medicine so you can get better. If you go to another country with the prescribtion they will know the exact amount of medicine that yo are taking because the metric system its known all over the world.
The metric system is used around the world to avoid mistakes, imagine that you are going into surgery and your doctor has to make a procedure on your skin and has to cut 3 inches from a tumor that you have, but the doctor gets sick and this day another doctor from other country has to make the surgery, he will probably make a mistake because inches its unit different that the one used in many countries.
