deci (d) 1/10th
Kilo (K) 1000
centi (c) 1/100th

Common base units
Ampheres (amps) current
Liter (L) Volume

Meter (M) Length
Second (s) time
Gram (g) measurement

Temperature conversions
Fahrenheit to Celsius
(F - 32) x .5556= C
Celsius to Fahrenheit
(C X 1.8) + 32 = F
Celsius to Kelvin
C + 273= K
Kelvin to Celsius
K - 273= C
Significant figures
non zeros
Every nonzero number is significant
left handed
zeros appearing to
the left of the first
nonzero number are
not significant.
right handed
Zeros at the end of a
number that are right of
the decimal are
significant
zero sandwich
Zeros between nonzero
numbers are significant.
weird zeros
Zeros that appear at the end
of the number BUT before the
decimal would be...when no
decimal is present
