Calculations Using Engineering Prefixes

Calculation can be executed in the NORMAL mode (excluding N-base), STAT mode and PROG mode using the following 12 types of prefixes.

Prefix	Operation	Unit
E (Exa)	@j0	1018
P (Peta)	@j1	1015
T (Tera)	@j2	1012
G (Giga)	@j3	109
M (Mega)	@j4	106
k (kilo)	@j5	103
m (milli)	@j6	10–3
∝ (micro)	@j7	10–6
n (nano)	@j8	10–9
p (pico)	@j9	10–12
f (femto)	@jA	10–15
a (atto)	@jB	10–18

Example	Key operations	Result
100m ⋅ 10k =	100 @j6k
	10 @j5e	1000.
