calculating frame size of MPEG file

Read the BitRate, SampleRate and Padding (as value of one or zero) of the frame header and use the formula:

FrameSize = 144 * BitRate / SampleRate + Padding

[B]Example: BitRate = 128000, SampleRate=441000, Padding=0 ==> FrameSize=417 bytes


what does 144 corresponds to ?
