• FAMILIARITY which is almost every nation excluding the united states has accepted the metric system as its official system of weight and measures.
• UNIFORMITY which is scientists use the metric system so all experiments are conducted using the same weights and measures.
• HISTORY which is the general session on weights and measures formally chosen six metric units to be used as international standards in 1954 and in 1960 and the meter was formally distinct established on the wavelength of light from krypton atoms.
• TYPES which is the metric system use meters for space, grams for mass, liters for volume and candelas for light.
