Values from Measurements The complete measurement is called a physical quantity. It consist of two parts: a number and a unit For example 100 meters = 100 m

MAGNITUDES DERIVED FUNDAMENTAL MAGNITUDES: MAGNITUDES: They are measured directly DERIVED MAGNITUDES: They are measured by a mathematics formula length time density surface temperature mass volume

IS UNIT Physical Property Name of Unit Symbol Lenght meter m Mass kilogram kg Time second s Temperature kelvin k Pág. 16

IS UNIT Length  meter, m: the distance that light travels in a vacuum in 1/299,792,458 of a second Mass  kilogram, kg: the mass of a platinum-iridium alloy cylinder in a vault in France Time  second, s: the duration of 9,192,631,770 periods of the radiation emitted in a specified transition between energy levels of cesium-133 Temperature  kelvin, K: 1/273.16 of the temperature difference between absolute zero and the triple point temperature of water
