How can I get processor speed of an Android device in MHz? I'm able to get the speed in terms of BogoMips by reading \proc\cpuinfo file. How can I convert BogoMips to MHz or is there any other way to get the speed in MHz?

If you're wondering how to check your clock speed, click the Start menu (or click the Windows* key) and type “System Information.” Your CPU's model name and clock speed will be listed under “Processor”.
In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in MHz (megahertz, or millions of pulses per second) or GHz (gigahertz, or billions of pulses per second).
A clock speed of 3.5 GHz to 4.0 GHz is generally considered a good clock speed for gaming but it's more important to have good single-thread performance. This means that your CPU does a good job of understanding and completing single tasks. This is not to be confused with having a single-core processor.
You have the maximum processor speed (in Hz) into the file:
/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
For instance, the content of that file in my Samsung Galaxy Ace is :
832000
117
The wikipedia page on BogoMips (http://en.wikipedia.org/wiki/BogoMips) gives a table providing a rough way of estimating between processor clock and bogoMips given the type of processor.
