Kilo- A “kilo” of cocaine is a kilogram

kilometer


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Deci-

Deci … just like in “decimal”… 10


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)


A cubic decimeter is a liter


Centi-

Same root as “century” or 100 years

How many centimeters to an inch?

2.54 cm


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Milli-

Has nothing to do with a “million”.

“Phelps by a millimeter”


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Micro- “Micro” is what refers to a millionth, not “milli”.

“Micro” means more than just “small”.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Micro-The sizes of bacteria are measured in micrometers.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Micro- A microwave oven uses radio waves with wavelengths measured in micrometers.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Nano-

“Nano” means more than just “really small”.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Nano-

The wavelengths of visible light in are in the hundreds of nanometers.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Nano-

Viruses are in the 10 nm to 200 nm range.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Pico-

The sizes of atoms are measured in picometers.


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Femto-The sizes of the nuclei of

atoms are measured in femtometers.

1x10-15


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Femto- Consider an atom which may be 400 pm across, but the nucleus is

less than 20 fm in diameter.1x10-15

The nucleus is 20,000 times smaller than an atom!


centi- = 1x10-2 (1/100)

milli- = 1x10-3 (1/1000)



Femto- If we put a dime on the floor to represent the diameter of the

nucleus, then the edge of the atom would be about 200 meters away.

1x10-15
