The Magna Carta (1215) also attempted to
standardize measurements throughout the kingdom,
although it concentrated on measures of beer and
wine.
true
2
dimensions divided into two areas
fundamental & derived
3
fundamental
length, mass, time, temp, electrical current, luminous intensity, (angle)
4
derived
velocity, acceleration, force, pressure, energy/work, power, frequency, electrical resistance, electrical potential, capitance,inductance, magnetic flux
5
dimensional systems
Absolute System
Dimensions are not affected by gravity.
Fundamental dimensions; Length (L), Time (T) & Mass(M).
Widely used in the scientific branches.
Example: SI System (a.k.a. Metric System)
Gravitational System
Gravitational force affects dimensions.
Fundamental dimensions; Lengh (L), Time(T) & Force(F).
Widely used in the engineering branches.
Example: US Customary System

International System of Units
Abbreviated SI from the French Le Système
International d'Unités
Modern form of the metric system
Developed in 1960 from the old metre‐kilogram‐
second system
The world's most widely used system of
measurement
9
base SI units
foundational units upon which all other units are based.
10
supplementary SI units
may be considered as base or derived units
11
derived SI units
formed by combining base, supplementary or other derived units
