Understanding SI Units and Notation

The video tutorial introduces engineering notation, highlighting its use of multiples of three, unlike scientific notation. It explains how to write numbers in engineering notation by moving decimals and using powers of ten. The tutorial covers SI prefixes as a shorthand for engineering notation, providing examples of converting numbers to SI notation. Finally, it introduces electronic symbols and units for electrical quantities, emphasizing the importance of understanding these concepts.

What is the main difference between engineering notation and scientific notation?

• Engineering notation uses fractions.
