There is no straight "formula" to convert Mbps to MHz, as there are several factors that affect the spectrum of the transmitted digital signals:

1. The number of bits per 'bit'. Sometimes a piece of transmitted information represents more than one actual digital bit.

2. The form of modulation (PAM, PCM, phase-modulation, QAM, BPSK, etc.)

3. For PCM modulation, the transmission method (NRZ, AMI, Bi-phase/manchester, RZ, RNRZ, etc.)

Each of these has a different spectrum. Some of them go down to DC while others have no DC component. Some of them use twice the analog bandwidth (in MHz) as the bit-rate in Mbps.

I have several textbooks, but they are at home, and I can't remember exact titles or authors. If I remember to look them up tonight, I'll edit this message. Then you can look up the information for yourself.
