hfe beta

What is the relation between hfe and beta of bipolar transistor?
 

relation between beta and hfe

There is a small difference. hfe is the small signal value and beta is a DC value. In the region of currents where beta is a constant the two are almost equal. At very low and very high values of currents they are not.
