At the end of the lesson you will understand SI units, identify base SI units, and convert derived units to base units.
What do you already know about SI units and their conversions?
Introduction to SI Units
SI Units, or the International System of Units, is the standard system of measurement used worldwide in science and engineering.
Base SI Units
There are seven base SI units: metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).
Derived SI Units
Derived units are combinations of base units. Examples include newton (N) for force and joule (J) for energy.
Why Convert Units?
Converting units allows engineers to communicate effectively and perform accurate calculations across various disciplines.
Conversion Factors
Conversion factors are used to convert one unit to another. They are ratios that express how many of one unit are equal to another.
Converting Derived Units
To convert derived units, express them in terms of base units and apply the appropriate conversion factors.
Interactive Exercise
Convert 100 km/h to m/s. Use conversion factors to express km/h in base units (m/s).
Common Mistakes
Common mistakes include incorrect conversion factors and unit cancellation errors.
