Table 22:
G = giga = 10^9
M = mega = 10^6
k = kilo = 10^3
d = deci = 10^1
c = centi = 10^2
m = milli = 10^3
u = micro = 10^6
n = nano = 10^9
p = pico =10^12
Derived Units
= Come from combining base units
Examples – volume and density
Volume
= space occupied by an object. Units – cubic meter or cubic centimeter
Liter = one cubic decimeter
Density
= mass/unit volume – ratio compares mass to an object’s volume
Example – g/cubic centimeter
Temperature
– measures (approximately) how hot or cold an object is
Kelvin
– Freezes at 273k. Boils at 373k. + 273 to Celcius = kelvin
