Lecture 1 Units Measurement Pdf International System Of Units Measurements in physics require defined standards and units in order to be quantitative. the international system of units (si) is the standard measurement system used which defines fundamental units like meters, kilograms, and seconds. Measurement demo: use a ruler to measure a pencil. we can measure the pencil down to the millimeter scale, so our measurement should have 3 or 4 significant figures.
1 Units And Measurement Pdf International System Of Units Kilogram All physical quantities must have units attached to them. the standard system of units is called the si (systeme internationale), or equivalently, the metric system. this system uses. with these abbreviations for the fundamental quantities, one can also be said to be using the mks system. 3. International system of units, international system of units: is the modern form of metric system, and is the widely used system of measurement. it comprises a coherent system of units measurement built on seven base units. Proper measurement requires defining the physical quantity, choosing appropriate units, and accounting for the precision of the measurement. download as a ppt, pdf or view online for free.

The s.i. base units are calculated from these seven definitions, after converting the derived units (joule, coulomb, hertz, lumen and watt) into the seven base units (second, meter, kilogram, ampere, kelvin, mole and candela). In 1960, an international committee established a set of standards for the fundamental quantities of science. it is called the si (system international), and its units of length, mass, and time are the meter, kilogram, and second, respectively. Lecture 1 free download as pdf file (.pdf), text file (.txt) or view presentation slides online. the document discusses measurement systems including classifications of standards, the international system of units (si), and measurement elements. To measure a physical quantity we compare it with a standard known as the unit of the quantity. each base quantity has a base unit (table 1.1). a quantity is written as its value followed by its unit, e.g. the height of a girl might be 1.40 m. the system we use is called the système international d’unités or the si system.
