There are 5 metric prefixes commonly used with electrical measurements; these are: mega,
kilo, milli, micro, and pico.
(1)
Mega, abbreviated M, means million. Since 1,000,000 can be expressed as 106, we can
substitute mega or M for 106.
For example: 88,000,000 Ω = 88 X 106 Ω = 88 M Ω.
(2)
Kilo, abbreviated k, means thousand. Since 1,000 can be expressed as 103, we can
substitute kilo or k for 103.
For example: 35,000 V = 35 X 103 V = 35 kV.
(3)
Milli, abbreviated m, means one thousandth part of. Since .001 can be expressed as 10-3, we
can substitute milli or m for 10-3.
For example: .002 A = 2 X 10-3 A = 2 mA.
(4)
Micro, abbreviated , means one millionth part of. Since .000001 can be expressed as 10-6,
we can substitute micro or for 10-6.
For example: .0000026 V = 2.6 X 10-6 V = 2.6 V.
(5)
Pico, abbreviated p, means one millionth of a millionth part of. Since .000000000001 can be
expressed as 10-12, we can substitute pico or p for 10-12.
For example: .000000000155 A = 155 X 10-12 A = 155 pA.
