&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;==Key Stage 4==&lt;br /&gt;
===Meaning===&lt;br /&gt;
'''Femtometres''' ('''fm''') are a [[unit]] of [[distance]], [[displacement]] and [[wavelength]] 1,000,000,000,000,000 times smaller than the [[SI Unit]]; the [[Metre]].&lt;br /&gt;
===About Femtometres===&lt;br /&gt;
:  '''Femtometres''' are shortened to '''fm''' with a lower case f and a lower case m.&lt;br /&gt;
: [[Pico]] means one quadrillionth so there are 1,000,000,000,000,000 [[femtometre]]s in a [[Metre]].&lt;br /&gt;
