Metrology is the basis for everything we measure
How many degrees, how much and how long is it? All over the world, things are constantly being measured. The science of measurement is called measurement technology, or metrology, and RISE is Sweden’s designated National Metrology Centre with responsibility for maintaining traceable measurement technology. Metrology is the basis for the International System of Units, or SI units. There are seven SI base units measuring length, mass, time, electric current, temperature, amount of substance and luminous intensity.
