What is Engineering Notation?

Definition : Engineering notation is a method of writing really big and really small numbers. In engineering notation, the exponent must always be a multiple of three so that it is equivalent to a value represented by a metric prefix.

Examples:

tera T 1,000,000,000,000 1012
giga G 1,000,000,000 109
mega M 1,000,000 106
kilo k 1,000 103
1 100
milli m 0.001 10¯3
micro ยต 0.000001 10¯6
nano n 0.000000001 10¯9
pico p 0.000000000001 10¯12
