The metric system of units is seen to have evolved into the International System of “SI” Units to provide primarily for defining other specifically-useful units; of which a more usefully Earth-related and Personally-related “Geospheric System of Units” is proposed to serve the growing worldwide needs to coordinate human activities with the nature of their Earthly-environment. That Geospheric System essentially extends the way in which unit-intervals of time and horizontal positions are customarily coordinated throughout the world; and could well first be utilized to serve the characteristic meteorological need to coordinate the vertical positions of things in and of the Earth's atmosphere.
